RS PRO Trace Heating Thermostat, -5 → +40 °C

Hazardous Area Thermostats

Designed for the control of surface temperatures of trace heating pipes and vessels within a hazardous area. Pipe sensing models have a protected capillary tube with surface mounting sensor bulb. Air sensing types have an air sensing model for frost protection purposes. All thermostats are adjustable over a temperature range and are 'ON – OFF' units with an electrical switch operated by expansion of the liquid in the sensing bulb or capillary. The units are suitable for use in corrosive and dust laden atmospheres.
