The temperature transmitter technology has been very mature, and it is very common in various factories. The temperature transmitter is often used in conjunction with some instruments, and there are often some small faults during the supporting use. The more common faults and solutions are as follows. First, the output of the transmitter does not change when the temperature of the measured medium increases or decreases. Most of these cases are caused by the sealing of the temperature transmitter. It may be because the temperature transmitter is not sealed well or is careless during welding. The sensor is welded with a small hole, which generally requires replacing the transmitter housing to solve. Second, the output signal is unstable. This reason is the reason of the temperature source, which is an unstable temperature. If the instrument display is unstable, it is the reason that the anti-interference ability of the instrument is not strong. Third, the output error of the transmitter is large, and there are many reasons for this situation. It may be that the resistance wire of the selected temperature transmitter is not correct, resulting in a wrong range, or it may be that the transmitter is not calibrated well when it leaves the factory.

The Role of 10k NTC Thermistors in Modern Temperature Sensing In 2025, 10k NTC thermistors are still a top choice for designers. They offer great sensitivity, cost-effectiveness, and compatibility with electronic systems.The “10k” refers to the nominal resistance at 25 °C—i.e. R25 = 10,000 Ω. This base point allows standardization across many applications.  NTC thermistors are negative temperature coefficient resistors: as temperature increases, resistance decreases.This behavior is sharper than metals or silicon resistors. It makes them very sensitive in many thermal monitoring tasks.  2. R-T Behavior & Modeling with Public Data A widely used reference is the Labfacility 10k NTC table (B25/85 = 3977 K), which maps temperature to resistance across –40 °C to +125 °C. Temperature (°C) Resistance (kΩ) –40 336.479 0 32.65 (approx) 25 10.00 50 3.747 90 0.916 This nonlinear response is typically modeled via the B-parameter or the Steinhart–Hart equation. For instance, Electronics Tutorials uses B = 3455 for a 10k NTC spanning 25 °C to 100 °C. ([electronics-tutorials.ws] 3. Critical Parameter Considerations 3.1 Tolerance & Beta Stability Common tolerances include ±1 %, ±2 %, ±5 %. For example, Amwei’s 10k device lists R25 ±1 % with Beta B25/85 = 3435 K ±1 %. [amwei.com] Stability of the Beta parameter over time and environmental cycling is crucial for long-term accuracy. 3.2 Thermal Time Constant & Self-Heating The thermal time constant for many 10k NTC units is around 10–15 seconds. For instance, Handson’s 10k-3950 spec sheet lists 15 s.Meanwhile, self-heating (due to the measuring current) can artificially raise the sensor’s temperature and distort readings. Designers must restrict excitation current to limit th...

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...

When it comes to measuring temperature, two common options are thermocouple vs thermistor. Both are reliable sensors, but they work in different ways and are suited to different applications. At Focusens, we specialize in high-quality temperature sensors, including thermistors, that deliver precise and consistent results. In this article, we will compare thermocouple vs thermistor to help you decide which one is the best fit for your needs. What is a Thermocouple? A thermocouple is a type of temperature sensor made from two different metals joined together at one end. This junction generates a small voltage that changes as the temperature changes. The voltage is then measured and converted into a temperature reading. Thermocouples are widely used in industrial and scientific settings because they can measure extremely high temperatures—up to 2,000°C (3,632°F) or more. They are also durable and perform well in harsh environments. What is a Thermistor? A thermistor is a temperature-sensitive resistor. Its resistance changes with temperature, either increasing (in the case of PTC thermistors) or decreasing (for NTC thermistors) as the temperature rises. Thermistors are known for their accuracy and sensitivity in lower temperature ranges, typically from -50°C to 300°C (-58°F to 572°F). Thermistors are commonly used in consumer electronics, medical devices, and industrial temperature control systems because of their precision and quick response times. Key Differences Between Thermocouples and Thermistors To help you understand the differences, let’s compare thermocouple vs thermistor across several important factors: 1. Temperature Range Thermocouples: Can handle extreme temperatures, from -200°C to over 2,000°C (-328°F to 3,632°F), depending on the type. Thermistors: Operate in a more limited range, typically from -50°C to 300°C (-58°F to 572°F). Thermocouples are better for high-temperature applications, while thermistors are ideal for low to moderate temperature ranges. 2. Accuracy Thermistors: Offer higher accuracy, especially in their specified temperature range. They can detect even small temperature changes with precision. Thermocouples: Less accurate compared to thermistors and may require regular calibration to maintain performance. If accuracy is your priority, thermistors are a better choice. 3. Response Time Thermistors: Have a fast response time due to their small size and high sensitivity. Thermocouples: Are generally slower but still provide a reliable response. For applications that require quick temperature readings, thermistors are more suitable. 4. Durability Thermocouples: Extremely durable and resistant to high heat, vibration, and harsh environments. They are commonly used in industrial settings and scientific experiments. Thermistors: While robust, they are not as durable as thermocouples in extreme conditions. For tough environments, thermocouples are a better option. 5. Cost Thermistors: Usually more affordable and cost-effect...
