CWF Precision NTC Thermistor Probes
for Temperature Measurement
The CWF series NTC Thermistors
are supplied in 5 basic styles of
enclosures designed to facilitate
installation in a wide variety of
applications. PVC leads are applied
to a precision, high-reliability NTC
thermistor, insulated with heat
conductive water resistant materials
and potted into any of a wide variety
of probe bodies. CWF thermistors
are also available with custom
housings or custom lead lengths for
remote sensing and temperature
control in difficult conditions.
