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.
