RTD type egt sensor Introduction
2024-08-02 15:27:20
Description
The platinum resistance temperature sensor measures temperature by using the property that the resistance of metal platinum changes with temperature. RTD is the most accurate and stable temperature sensor, and its linearity is better than that of thermocouples and thermistors. However, RTD is also the slowest and most expensive temperature sensor. Therefore, RTD is most suitable for applications where accuracy is strictly required, but speed and price are not critical. Our company's RTD sensor uses Pt200 as a resistor, which can improve the stability and accuracy of the temperature sensor and extend the service life of the sensor.
Production process
1. Material preparation: Select Pt200 as the resistance material of the sensor.
2. Prepare the sensor element: Process Pt200 into a thin film or filament form, and then fix it on a ceramic or glass substrate through printing, evaporation and other processes to form the resistance element of the sensor.
3. Package assembly: Encapsulate the prepared resistance element in a protective shell, usually made of stainless steel or other corrosion-resistant materials, to protect the sensor element from the external environment.
4. Calibration test: Calibrate and test the produced RTD temperature sensor to ensure that its measurement accuracy and stability meet the requirements.
5. Finished product inspection: Perform final finished product inspection on the calibrated sensor, including appearance inspection, performance test, etc., to ensure that the product quality meets the standards.
