The CT thermostat supports temperature control of heating circuits in safe or hazardous environments.
Technical adviceA CT thermostat is temperature adjustable ON-OFF thermostat that consists of a liquid-filled sensing bulb connected via a capillary to an electrical switch.
Expansion of the liquid as the temperature rises causes the switch to open and it closes as it cools.
Capstats can control surface temperatures, such as pipes or vessels, or the sensor lamp can be positioned to measure air temperature.
They can be used to control process temperatures in safe or Zone 1 or 2 hazardous environments by switching the heat circuits to the desired temperature, and are available for Group llA, llB or llC gases.
