Temperature Measurement With Thermistor Sensor
The thermistor sensor, which is used to measure temperature, is simple in structure and low in price.
Thermistors without external protective layers can only be used in dry areas; sealed thermistors are resistant to moisture and can be used in harsh environments.
Because the resistance value of thermistor sensor is relatively large, the resistance and contact resistance of its connecting wires can be ignored.
Therefore, thermistor sensor can be applied in long-distance temperature measurement up to several thousand meters, and the measurement circuit mostly adopts bridge.
The principle can also be used for other temperature measurement, temperature control circuit.
