Pt100 temperature sensor performance judgment

1, consistency judgement, the same type, same manufacturer of temperature sensor products best purchase of more than two at a time, the more the clear problem, together electricity output value contrast detection, under the condition of relatively stable, observe the consistency of the test. If further testing, but within 24 h intervals for a period of time, a day usually have high, medium and low three temperature and temperature conditions, can be more comprehensive observation of consistency and stability of the product.

2, mouth breath iced or use other humidification technique of sensor humidification, observe its acuity, repeatability, wet the dehumidifying performance, and break up rate, the highest range of products, etc.

3, in the high temperature and low temperature state of product testing, and restore to the normal state before testing and experiment comparison, assessment of product temperature adaptability, and watch the product of the same temper. The performance of the product finally formal complete detection methods according to the quality inspection department.

4, to product for open box testing and closed box of two cases. Contrast is consistent, the thermal effect was observed.
