Temperature sensors are critical in many industries, from manufacturing and automotive systems to healthcare and energy production. One of the most accurate and stable options for temperature measurement is the RTD sensor. At Focusens, we specialize in high-quality RTD sensors designed for a wide variety of applications. In this article, we will explain what RTD sensors are, how they work, and where they are used. We will also discuss the advantages of using RTD sensors in your applications. What is an RTD Sensor? An RTD sensor (Resistance Temperature Detector) is a type of temperature sensor that measures temperature by correlating the resistance of a material, typically platinum, with temperature. As the temperature increases, the resistance of the platinum wire increases in a predictable and linear way. This simple yet effective relationship makes RTD sensors highly accurate, stable, and reliable. The most common type of RTD sensor is the PT100, which has a resistance of 100 ohms at 0°C. There are also PT500 and PT1000 sensors, with resistance values of 500 ohms and 1000 ohms, respectively, at 0°C. How Do RTD Sensors Work? The working principle of an RTD sensor is based on the fact that the electrical resistance of certain materials increases with temperature. When current flows through the RTD element, which is typically a fine platinum wire, the resistance of the wire changes with the surrounding temperature. The change in resistance is measured and converted into a temperature reading. The relationship between resistance and temperature is highly predictable and nearly linear for platinum RTDs. This allows for accurate and precise temperature measurements. Typically, the resistance-to-temperature relationship is based on standardized equations, such as the Callendar-Van Dusen equation, or is derived from a lookup table for platinum-based sensors. Types of RTD Sensors RTD sensors come in different types, each designed for specific applications. The main types of RTD sensors are: PT100: The most commonly used type of RTD sensor. It has a resistance of 100 ohms at 0°C. PT100 sensors are widely used in industries requiring accurate temperature monitoring, such as industrial automation, HVAC systems, and laboratories. PT500: This RTD sensor has a resistance of 500 ohms at 0°C. PT500 sensors are used in applications where higher resistance is needed, such as in high-precision temperature measurement systems. PT1000: With a resistance of 1000 ohms at 0°C, PT1000 sensors are suitable for applications requiring higher resistance, such as long-distance signal transmission or systems with a lower signal-to-noise ratio. Thin-Film RTDs: Thin-film RTD sensors are constructed by depositing a thin layer of platinum onto a ceramic substrate. These sensors are cost-effective and commonly used in general-purpose applications, such as consumer electronics and automotive systems. Wire-Wound RTDs: These are constructed by winding a fine platinum wire around a ce...

Thermistor vs Thermocouple: Accuracy, Range and Response Compared A thermistor is a ceramic resistor whose resistance changes with temperature; a thermocouple is a junction of two metals that produces a small voltage. Near room temperature a good NTC thermistor is the more accurate of the two: a 10k part with ±1 % R25 and ±1 % B is within ±0.23 °C at 25 °C by our calculation, while a class 1 type K thermocouple is allowed ±1.5 °C (IEC 60584-1). The NTC's error grows away from 25 °C and passes the type K class 1 limit at about 110 °C. Coated NTCs stop at 125-150 °C and glass-encapsulated ones at about 250 °C; above that, a type K thermocouple covers the range up to about 1200 °C. Which one responds faster depends on the probe construction more than on the sensing principle. Updated 15 October 2026: rewritten with tolerance figures per temperature, published response-time data and a selection table. Reviewed by the Focusens Engineering Team. The comparison in one table Property NTC thermistor Thermocouple (type K) PT100 RTD, for reference How it works Resistance falls as temperature rises Voltage set by the temperature difference between the measuring junction and the cold junction Resistance rises almost linearly Typical range -40 to 125 °C for coated parts (Vishay NTCLE100E3); up to 250 °C glass-encapsulated (TDK G1541) -200 to about 1200 °C; the usable top end depends on sheath size and material (TC Direct) -200 to 850 °C (IEC 60751) Tolerance at 25 °C ±0.23 °C (±1 % R25, ±1 % B) ±1.5 °C, class 1 ±0.20 °C, class A Tolerance at 100 °C ±1.30 °C (same part) ±1.5 °C, class 1 ±0.35 °C, class A Signal at 25 °C 10 kΩ, changing about 4.4 % per °C Around 40 µV per °C About 0.39 Ω per °C What the input needs A bias resistor or current, plus a table or Steinhart-Hart fit Cold-junction compensation and a microvolt input A small constant current, 3- or 4-wire for accuracy Lead wire Ordinary copper; at 10 kΩ the leads hardly matter Thermocouple or matching extension wire all the way to the input Copper, but lead resistance counts on 2-wire The NTC figures are our calculation for a 10 kΩ, B = 3950 part; the method is in the next section. Accuracy: the thermistor wins near room temperature An NTC thermistor's error comes from two tolerances: the resistance at 25 °C (R25) and the B value that sets the curve. At 25 °C only the R25 tolerance counts. Away from 25 °C the B tolerance adds in, so the error grows in both directions. TDK and Vishay both describe the spread this way. A thermocouple's tolerance is fixed by class in IEC 60584-1:2013: for type K class 1 it is ±1.5 °C from -40 to 375 °C, then ±0.4 % of the temperature. The standard is clear that these tolerances apply to the wire as delivered and do not include drift in use. Neither do they include the instrument's cold-junction compensation error, which adds on top in a real system.

In the world of temperature sensors, negative temperature coefficient (NTC) thermistors are among the most reliable and accurate components used to measure temperature. At Focusens, we specialize in high-quality NTC thermistors designed for a wide range of applications. This article will explain what NTC thermistors are, how they work, and where they are used. We will also highlight the advantages of choosing NTC thermistors for various temperature sensing needs. NTC thermistors are one of four core temperature sensor technologies used in modern industrial and consumer applications. For a complete comparison of NTC vs PTC thermistors, PT100/PT1000 RTDs, and thermocouples across accuracy, temperature range, and signal processing requirements, see our temperature sensor types complete comparison guide. For the NTC against a PT100 alone, with the tolerance of each at every temperature, see our RTD vs thermistor comparison. What is a Negative Temperature Coefficient Thermistor? A negative temperature coefficient (NTC) thermistor is a type of thermistor whose resistance decreases as the temperature increases. This means that as the temperature rises, the NTC thermistor’s resistance becomes lower, which is in contrast to positive temperature coefficient (PTC) thermistors, where the resistance increases as temperature increases. NTC thermistors are made from metal oxide materials that exhibit this negative temperature coefficient, and they are highly sensitive to small changes in temperature. This makes them ideal for precise temperature measurements in various applications, from industrial settings to consumer electronics. How Do Negative Temperature Coefficient Thermistors Work? The basic principle behind NTC thermistors is simple: the resistance of the thermistor decreases as the temperature increases. This relationship is used to measure the temperature of the environment where the thermistor is placed. The change in resistance due to temperature is measured by passing a small electrical current through the thermistor. When the temperature increases, the resistance of the NTC thermistor decreases, allowing more current to flow. This change in resistance can be measured and used to calculate the temperature of the thermistor’s surroundings. Because NTC thermistors are highly sensitive, they can provide accurate and quick temperature readings, even for small temperature fluctuations. Types of Negative Temperature Coefficient Thermistors NTC thermistors come in various types depending on their application. Here are the most common types of NTC thermistors: High-Precision NTC Thermistors These thermistors are designed for applications where high accuracy is required. They provide very precise resistance-temperature characteristics and are used in sensitive measurement systems. Standard NTC Thermistors These thermistors offer a balance between performance and cost. They are commonly used in general temperature sensing applications, including industrial p...

In the world of temperature sensing, RTD sensors (Resistance Temperature Detectors) are among the most reliable and accurate components available. At Focusens, we specialize in providing RTD sensors that offer high precision, stability, and long-term reliability for a wide variety of industries. Whether used in industrial automation, automotive systems, or medical devices, RTD sensors are essential for accurate temperature measurement. Let’s take a closer look at how RTD sensors work, their types, applications, and benefits. What is an RTD Sensor? An RTD sensor is a type of temperature sensor that measures temperature based on the change in resistance of a material, typically platinum, as temperature changes. The core working principle of an RTD sensor is simple: as temperature increases, the resistance of the material increases in a predictable manner. This relationship between resistance and temperature makes RTD sensors highly accurate and suitable for precise temperature measurements. RTD sensors are widely used in applications requiring high accuracy, stability, and repeatability. The most common type of RTD sensor is the PT100, which has a resistance of 100 ohms at 0°C. How Do RTD Sensors Work? RTD sensors are typically made from a pure metal like platinum because of its stable and linear relationship between resistance and temperature. The sensor consists of a thin wire or film of platinum, and its resistance changes as the temperature around it fluctuates. This change in resistance is then measured, and the corresponding temperature is calculated based on pre-defined calibration data. To measure temperature, an electrical current is passed through the RTD sensor element. As the current flows, the resistance of the platinum wire changes in response to the temperature. This change in resistance can be measured and converted into a precise temperature reading. Types of RTD Sensors There are several types of RTD sensors, with different designs and characteristics. The most common types include: PT100: PT100 sensors are the most widely used RTD sensors, with a resistance of 100 ohms at 0°C. They offer high accuracy and stability, making them ideal for a wide range of applications. PT1000 sensors are similar but have a resistance of 1000 ohms at 0°C. These sensors are used in applications where higher resistance values are needed. Thin-Film RTDs: These RTD sensors are constructed by depositing a thin layer of platinum onto a ceramic or glass substrate. Thin-film RTD sensors are cost-effective and provide good performance for general-purpose applications. Wire-Wound RTDs: These RTD sensors are made by winding a fine platinum wire around a ceramic core. They offer excellent accuracy and stability, making them suitable for high-precision measurements in industrial settings. Surface Mount RTDs: These RTD sensors are designed to be mounted directly onto surfaces to measure the temperature of equipment, machinery, or other components. They are widely...

PTC sensors, or Positive Temperature Coefficient sensors, are vital components used to monitor and control temperature in a wide variety of applications. At Focusens, we specialize in providing high-quality PTC sensors designed for accuracy and reliability. This article explores the working principle, types, and applications of PTC sensors, helping you understand their important role in modern technology. What is a PTC Sensor? A PTC sensor is a type of temperature sensor whose resistance increases as the temperature rises. The term “positive temperature coefficient” refers to this characteristic. As the temperature increases, the resistance of the material inside the PTC sensor increases proportionally. This property is what makes PTC sensors ideal for use in temperature sensing, overcurrent protection, and self-regulating heating applications. How Do PTC Sensors Work? The working principle of a PTC sensor is straightforward. PTC materials, typically made from ceramics or polymers, exhibit a resistance that increases sharply with temperature. In a typical setup, when the temperature exceeds a certain threshold, the sensor’s resistance increases dramatically, reducing the current flowing through the circuit. This makes PTC sensors useful for temperature protection and overload protection in electrical circuits. For example, in an overcurrent protection circuit, when the current rises too high, the PTC sensor heats up, causing its resistance to increase and limiting the current flow. This helps prevent damage to other components, such as motors or circuits, by reducing the excessive current. Types of PTC Sensors PTC sensors come in several types, each suited for different applications. Below are the most common types: Resettable PTC Sensors These sensors are self-regulating, meaning they automatically reset after the temperature returns to a safe range. Once the temperature exceeds the threshold, the resistance increases, reducing the current. When the temperature drops, the resistance decreases, allowing normal current flow to resume. These sensors are widely used in overload protection and thermal switches. Fixed PTC Sensors Fixed PTC sensors have a permanent increase in resistance after reaching a certain temperature. They are used in applications where once the temperature limit is reached, the sensor needs to stay in a high-resistance state, like in over-temperature protection systems. High-Temperature PTC Sensors These sensors are designed to operate at very high temperatures and are commonly used in industrial applications. Their high-temperature resistance characteristics are ideal for monitoring extreme temperature conditions, such as those found in furnaces or industrial machinery. Low-Temperature PTC Sensors Low-temperature PTC sensors are used in sensitive applications that require precise temperature control at lower temperatures. They are often used in devices that need to maintain a consistent, low temperature without exceeding criti...
