Explosion Proof Temperature Switches

SOR explosion proof temperature switches work on a proven, time-tested vapor pressure thermal system. Changes in fluid vapor pressure may be accurately predicted according to the influence of temperature on the switch’s sensing bulb. When the temperature in the process changes a proportional adjustment in the vapor pressure occurs in the sensing bulb. The change acts on the diaphragm/piston assembly to actuate/de-actuate an electrical, snap-action switching element at discrete process temperatures.
