Thermistor (271-0110) Hints and Tips Faxback Doc. # 31962 The AT Thermistor is a high-precision thermal sensitive element whose resistance and B constant tolerance are extremely small. When the AT Thermistor is used as a temperature sensor, no adjustment is required between the control circuit and the sensor, thus ensuring a temperature precision of +0.3 degrees Celsius. High-precision temperature control and temperature display are now available with the AT thermistor. (IR-03/21/96)
