RTD sensors, or Resistance Temperature Detectors, are widely used for measuring temperature due to their accuracy and reliability. These sensors operate on the principle that the resistance of certain metals, typically platinum, changes with temperature. The PT1000 sensor is a popular type of RTD sensor, and it operates based on the same fundamental principle. Here’s how RTD sensors, like the PT1000 sensor, measure temperature based on changes in resistance: 1. Understanding the PT1000 Sensor The "PT" in PT1000 refers to platinum, the material commonly used for the RTD element. The number "1000" signifies that the sensor has a resistance of 1000 ohms at 0°C, the reference temperature. The PT1000 sensor typically consists of a thin wire or a film of platinum wrapped around a ceramic core. Platinum is chosen due to its near-linear and repeatable change in resistance with temperature, making it ideal for accurate temperature measurement. RTD sensor manufacturers often favor platinum for its reliability in various industries. 2. Principle of Operation: Resistance and Temperature RTD sensors, like the PT1000 sensor, function based on the relationship between temperature and resistance. Platinum, like most metals, has a positive temperature coefficient (PTC), meaning its resistance increases as the temperature rises. For a PT1000 sensor, the resistance increases by approximately 3.85 ohms per degree Celsius. If the temperature increases by 1°C, the sensor's resistance increases by 3.85 ohms. This predictable, near-linear relationship makes the PT1000 a reliable choice for precise temperature measurements, which is why RTD suppliers value this sensor type for their product portfolios. 3. Measuring Resistance to Determine Temperature To measure temperature using a PT1000 sensor, an electrical circuit measures the resistance of the sensor. Typically, a Wheatstone bridge or a 4-wire measurement method is used for greater accuracy. Here’s how the process works: · Current is passed through the RTD sensor: A known current is applied to the RTD sensor, and the voltage drop across the sensor is measured. · Resistance is calculated: Using Ohm’s Law (V = IR), the resistance of the PT1000 sensor is calculated based on the measured voltage and the known current. · Temperature is calculated: The resistance value is compared to a pre-established temperature-resistance curve for platinum, providing an accurate temperature reading. 4. Standard Temperature-Resistance Relationship for PT1000 There are two typically TCR（temperature coefficient of resistance）of PT1000/PT100 ,that is 3850 ppm/K and 3750 ppm/K, Focusens mainly use the one with 3850. Our PT1000 sensor follows a specific standard for resistance values at different temperatures. TCR = 106. (R100– R0)/ 100 · R0  [ppm/K] For example: · At 0°C, the PT1000 has a resistance of 1000 ohms. · At 100°C, the resistance is approximately 1385 ohms. · At 200°C, the resistance is approximately 1770 ohms. This standard allows...

Temperature sensors play a critical role in modern industries. Among the most popular options are PT100 and PT1000 sensors, both of which are Resistance Temperature Detectors (RTDs). These sensors provide accurate and reliable temperature measurements. However, the PT1000 offers distinct advantages over the PT100 in certain applications. Let’s explore what sets the PT1000 apart and why it may be the better choice for your temperature measurement needs. What Are PT100 and PT1000 Sensors? Both PT100 and PT1000 sensors measure temperature based on the resistance of platinum. As the temperature changes, so does the platinum's resistance. The difference lies in their resistance values: PT100: 100 ohms at 0°C. PT1000: 1000 ohms at 0°C. This higher resistance in the PT1000 sensor has significant implications for its performance. Advantages of PT1000 Over PT100 1. Better Accuracy in Long-Distance Applications When using temperature sensors, the length of the wire connecting the sensor to the measuring device can impact accuracy. Longer wires create additional resistance, which may distort readings. With the PT1000’s higher resistance, the impact of the wire resistance becomes less significant. This makes it ideal for applications requiring long cable runs, such as industrial automation or remote monitoring. 2. Reduced Sensitivity to Electrical Noise In environments with high levels of electrical interference, such as factories or power plants, noise can affect sensor accuracy. The PT1000’s higher resistance reduces its sensitivity to such interference, providing more stable and reliable readings. 3. Lower Current Requirements The PT1000 sensor requires less current to measure resistance compared to the PT100. Lower current minimizes self-heating, a phenomenon where the sensor slightly warms up and alters its own reading. This makes the PT1000 more suitable for applications requiring high precision, such as laboratory experiments or medical devices. 4. Cost Efficiency in 2-Wire Configurations Temperature sensors often use 2-wire, 3-wire, or 4-wire setups to compensate for wire resistance. In a 2-wire system, the PT1000 provides better accuracy without the need for extra compensation, reducing costs and complexity. 5. Wide Application Range The PT1000 sensor can be used in a broader range of applications due to its versatility and performance. It is commonly found in: HVAC systems: To monitor heating and cooling efficiency. Medical equipment: Where precision is crucial. Automotive industry: For engine temperature monitoring. Industrial automation: In process control systems. Where PT100 Might Still Be Better While the PT1000 offers many advantages, the PT100 remains a reliable choice for specific scenarios: High-Temperature Environments: PT100 sensors are often more robust at extremely high temperatures. Legacy Systems: Some older equipment is designed specifically for PT100 sensors. Always consider the specific needs of your application before making a de...

PT100 vs PT1000: Which RTD to Choose and When It Matters PT100 vs PT1000 is a choice about wiring and electronics, not about accuracy. Both are platinum RTDs on the same IEC 60751 curve with the same tolerance classes in °C; a PT1000 reads exactly ten times a PT100, 1000 Ω at 0 °C against 100 Ω. Choose a PT1000 for 2-wire connections and long thin cables, where the same lead resistance causes one tenth of the error, and for low-power electronics. Choose a PT100 when the transmitter or PLC card only accepts PT100, when you need a wire-wound element, or when a 3-wire or 4-wire loop already cancels the lead resistance. Updated October 19, 2026.

IEC 60751:2022, the standard for industrial platinum RTDs, defines one resistance curve and scales it by the nominal resistance: the table values "shall be multiplied by the factor R0 / 100 Ω". Its tolerance classes apply "for any value of R0" and are expressed in °C. A Class A PT1000 and a Class A PT100 therefore have the same allowed error, ±(0.15 + 0.002 |t|) °C. In ohms the tolerance is ten times larger on a PT1000, which matters when you check parts at incoming inspection: Class Tolerance at 0 °C PT100 PT1000 Tolerance at 100 °C PT100 PT1000 AA ±0.10 °C ±0.039 Ω ±0.39 Ω ±0.27 °C ±0.10 Ω ±1.02 Ω A ±0.15 °C ±0.059 Ω ±0.59 Ω ±0.35 °C ±0.13 Ω ±1.33 Ω B ±0.30 °C ±0.117 Ω ±1.17 Ω ±0.80 °C ±0.30 Ω ±3.03 Ω Our calculation: IEC 60751 tolerance formulas times the slope at each temperature. WIKA, a German instrument maker, says the same about the rest of the behavior: "Linearity of the characteristic curve, operating temperature range, and response time are the same for both" (WIKA blog). Neither curve is linear. The slope of a PT100 falls from 0.391 Ω/°C at 0 °C to 0.379 Ω/°C at 100 °C, and a PT1000 falls in exactly the same proportion, so both need the IEC equation or a table rather than a straight line. The full tables are in our PT100 resistance table and PT1000 resistance table. Where a PT1000 wins: 2-wire connections and long cables A PT1000 wins wherever lead resistance is not canceled, which in practice means 2-wire connections. In a 2-wire circuit the instrument reads the element plus both leads, and every ohm of cable reads as extra temperature: 2.56 °C per ohm on a PT100 and 0.256 °C per ohm on a PT1000 a...

What Is an RTD? Resistance Temperature Detector Guide An RTD (a resistance temperature detector) is a temperature sensor whose electrical resistance rises in a fixed, predictable way as it gets hotter. The element is almost always platinum, and the resistance-to-temperature relationship is standardized by IEC 60751, not left to each manufacturer. A PT100 element reads 100.00 Ω at 0 °C. A PT1000 reads 1000.0 Ω at the same point. Because the curve is standardized rather than proprietary, a compliant PT100 from one maker is interchangeable with one from another. Those are the definitions. The error budget around them is what decides whether a measurement is any good, and a tolerance-class number alone does not capture it. Published November 8, 2024. Updated October 27, 2026. Reviewed by the Focusens Engineering Team. How an RTD measures temperature The principle is simple: as temperature rises, the atoms in the platinum element vibrate more and block the flow of current more, so resistance rises too. A current is passed through the element, the voltage drop is measured, and that resistance is converted into a temperature reading with a known equation. IEC 60751:2022, edition 3.0, published 27 January 2022, specifies that equation, referred to the International Temperature Scale of 1990. The metrological basis for that scale is documented in the BIPM's Guide to the Realization of the ITS-90, chapter 5, Platinum Resistance Thermometry. Above 0 °C: R(t) = R₀ · [1 + A·t + B·t²] Below 0 °C, a third term is added: R(t) = R₀ · [1 + A·t + B·t² + C·(t − 100)·t³] with A = 3.9083 × 10⁻³ °C⁻¹, B = −5.775 × 10⁻⁷ °C⁻², and C = −4.183 × 10⁻¹² °C⁻⁴. R₀ is the resistance at 0 °C: 100 Ω for a PT100, 1000 Ω for a PT1000. Every value in the table below comes from those equations and can be reproduced in a spreadsheet. Temperature PT100 PT1000 Slope at that point −200 °C 18.52 Ω 185.2 Ω 0.432 Ω/°C 0 °C 100.00 Ω 1000.0 Ω 0.391 Ω/°C 100 °C 138.51 Ω 1385.1 Ω 0.379 Ω/°C 200 °C 175.86 Ω 1758.6 Ω 0.368 Ω/°C 400 °C 247.09 Ω 2470.9 Ω 0.345 Ω/°C 600 °C 313.71 Ω 3137.1 Ω 0.322 Ω/°C 850 °C 390.48 Ω 3904.8 Ω 0.293 Ω/°C Values calculated from the IEC 60751 coefficients above. This is where a common assumption breaks down. RTD response is close to linear, not perfectly linear. The slope column above falls by about a quarter between the ice point and 850 °C. A single-multiplier conversion (the familiar "0.385 Ω/°C" figure is just the 0 to 100 °C average) drifts noticeably above roughly 150 °C. For most process-control ranges that drift is small enough to ignore; for wide-span or high-temperature work it is not. Full lookup values across the whole range are in the PT100 resistance table. Calculated directly from the IEC 60751 coefficients in the table above — not a measured trace. The dashed line is the 0.385 Ω/°C average slope (0–100 °C) extended as if it held everywhere; it does not.
