RTDs (Resistance Temperature Detectors)

Watlow manufactures a variety of resistance temperature detectors (RTD) sensors that are specially designed to ensure precise and repeatable temperature measurement.
Watlow sensors are built to meet the most demanding industrial applications while providing a lower total cost of ownership for our customers.


Watlow thermistors are designed to ensure fast, accurate and repeatable temperature measurement. Thermistors are highly sensitive to small changes in temperature and maintain accurate temperatures over a limited range. These sensors are made with either epoxy-coated or glass-coated constructions and can be used in the most demanding environmental conditions.


ENVIROSEAL HD temperature sensor keeps out moisture, oil and contaminants in all heavy-duty applications including those outside applications exposed to harsh weather, oils and other extreme moisture environments.
