Description

Spectrum Sensors & Controls assembly A1004AS20T1 is a general purpose thermistor probe for temperature sensing and is listed with Underwriters Laboratories (Certification file E193945). This sensor can be used to monitor air temperature or can be screw mounted for surface temperature measurement. The assembly consists of a highly stable NTC thermistor that is epoxied into an aluminum housing. The thermistor is a 10kW thermistor with an accuracy of ±0.2ºC from 0C to 70ºC. The sensor leads are AWG#20, teflon insulated UL rated wire. Sleeving is used to provide strain relief and to guarantee the UL rated 400 volt isolation between the sensor and the housing, The assembly is UL rated for operation to 105ºC.
