PT100 thin film resistor

Precautions for application of CRZ thin film elements:

 

1. When directly using components or making temperature sensors to measure temperature, avoid exceeding the temperature measurement range. Although it will not be damaged in a short time, it will also affect the product life and accuracy.

 

2. When assembling the temperature sensor with CRZ element, pay attention to the change of stress during the curing process when using high-temperature curing epoxy adhesive for potting, otherwise the element may be damaged (generally open circuit); During the filling process with magnesium oxide or aluminum oxide, the element shall not directly contact the sharp inner surface of the protective tube, otherwise, the ceramic edge of the element may be damaged during the vibration process, resulting in open circuit damage of the element.

 

3. When manufacturing the temperature sensor, the high insulation performance of the potting material must be ensured, otherwise the electrical insulation performance of the product will be reduced, and the test data of the components will be affected, which will generally lead to the low test resistance value.
