PT100 platinum thin film thermal resistor temperature sensor and advantages of manufacturing process

PT100 platinum thin film thermal resistor temperature sensor by a high purity platinum meander-line light KeFa adhere to the ceramic substrate. After laser trimming resistance accurately adjust to the final resistance, resistance of structure and glass passivation layer of protection, the sensor and chemical corrosion resistant to mechanical damage. Welding wire part is covered by additional fixed layer.

PT100 platinum thermal resistance temperature sensor membrane properties

1, fast response time;
