Diffusion resistance temperature sensor

Diffusion resistance temperature sensorResistor formed on the silicon semiconductor electrode, a voltage is applied when the electrode, the resulting change in the diffusion resistance with temperature. This feature can be made using a temperature sensor. So that it can get low cost, the excellent performance of the sensor. Resin-based Engine Coolant Temperature Sensor response speed, the air of 5s, the temperature coefficient of 0.72% / ℃, than nickel wire resistance type sensor 0.5% / ℃ 22% higher.
