## Summary description

Pt1000 temperature sensor, resistance 1 kΩ, Class B accuracy (0.12%), compact dimensions 2×3×1 mm. Designed for precise temperature measurement in instrumentation, HVAC, laboratory equipment and embedded systems. Offers stable resistance-to-temperature response, easy integration into circuits, and suitability for applications requiring small form factor and reliable readings.

## Long description

Pt1000 temperature sensor with nominal resistance 1 kΩ and Class B accuracy (0.12%) in a compact package measuring 2×3×1 mm. The sensor provides a predictable resistance-to-temperature relationship suitable for precision measurement in instrumentation, HVAC systems, laboratory equipment and embedded electronics. Small physical size enables placement in confined spaces and close thermal coupling to measured media while maintaining stable output over typical operating ranges.
Advantages
This Pt1000 Class B sensor delivers a high level of measurement stability and repeatability due to its platinum sensing element and standardized temperature coefficient. The Class B tolerance (0.12%) balances precision and cost for many industrial and scientific applications. Its compact dimensions allow integration into small assemblies and PCBs, and the sensor's linear resistance response simplifies signal conditioning and calibration in both analog and digital measurement systems.
Suitable for
Temperature measurement in instrumentation and test equipment
HVAC control and environmental monitoring
Laboratory apparatus and sample chambers
Embedded systems and compact electronic devices
Close-contact sensing in confined or miniature assemblies
Key specifications
Sensor type: Platinum resistance thermometer (Pt1000)
Nominal resistance at 0 °C: 1000 Ω
Accuracy class: Class B (0.12% tolerance)
Physical dimensions: 2 × 3 × 1 mm
Temperature-to-resistance characteristic: standardized platinum RTD curve (IEC/ITS-90 compatible behavior)
Package: compact solid-state element suitable for PCB or close-contact mounting
How to use
Mount the sensor so that it has good thermal contact with the measured medium or surface; when used on a PCB, ensure thermal coupling and avoid heat sources that could bias readings. Connect the sensor in a suitable measurement circuit such as a 2-, 3- or 4-wire RTD configuration depending on required accuracy and lead resistance compensation. Use an appropriate excitation current that stays within the sensor's power dissipation limits to prevent self-heating. Implement signal conditioning — for example, a precision constant current source and a high-resolution ADC or dedicated RTD converter — and apply the standard Pt1000 resistance-to-temperature conversion (ITS-90) or the calibration curve provided by your measurement system.
Usage recommendations
For best results, use a 3- or 4-wire connection in applications where lead resistance or long cable runs could affect accuracy. Minimize self-heating by keeping excitation current low and allow the sensor to reach thermal equilibrium before taking critical measurements. When mounting in airflow or liquids, provide secure mechanical placement and consider protective coatings or housings if the environment is corrosive or abrasive.
