Insulated Lead Interchangeable Chip Thermistor



Sensor Scientific KWM Series interchangeable wafer thermistors combine a high-accuracy thermistor with a tough insulated lead. The Kynar lead insulation offers many of the advantages of Teflon insulation with a lower cost. Interchangeability eliminates the burden of individual calibration. Units are available in resistance values from 2k ohms to 100k ohms @ 25°C. The available resistance vs. temperature curves (SSi curves C, D, E & Y) are industry-standard. If a standard unit does not meet your needs, customized tolerances, resistance values, temperature ranges, and termination options are available. Design assistance is also available.
