SOR Direct or Remote Mount Explosion Proof UL/CSA/ATEX - Manual

Form 416 (01.13) ©SOR Inc. 1/8
These instructions provide information for installation and
field calibration of B Temperature Switches.
Process temperature changes cause proportional
vapor pressure changes in the temperature sensing
bulb that acts on a diaphragm/piston assembly to
actuate and deactuate a snap-action electrical switching
element at discrete process temperatures. The instrument’s
behavior is determined by vapor pressure (105 range model
fill media is inert gas). For best results with the SOR
®
thermal activated temperature switch, the entire probe
must experience the media being monitored. If a
thermowell is being used, a thermal paste is recommended
to ensure the transfer of heat through the well to the probe.
