HIGH PRECISION THERMISTOR
AT THERMISTOR
The AT thermistor is a high-precision thermal
sensing device featuring extremely small
B-value tolerance and resistance.
When used as a temperature gauge, the AT
thermistor requires no adjustment between
the control circuit and the sensor.
This insures temperature precision of Ϯ0.3ЊC.
Temperature indicators and control instruments
are now available for use with the thermistor.

*1 R25 : Rated zero-power resistance value at 25ЊC.
*2 B value : determined by rated zero-power resistance at 25ЊC and 85ЊC.
*3 Time when thermistor temperature reaches 63.2% of the temperature difference. The value is measured in the air.
