Temperature Sensors & Switches

Temperature sensors and switches both act on heat in a process: a sensor converts a reading into a signal a controller can use, while a switch opens or closes a contact once a set point is crossed. Process engineers instrument a line when a bearing or winding needs watching before it fails, when a heater circuit has to cut out at a fixed limit with no controller involved, or when a space needs detection that trips on a rapid rise in heat.

 

As an authorized electrical distributor for multiple manufacturers, we stock temperature sensors, temperature switches and heat detectors from Honeywell, Edwards Signaling, Kele and more across competing lines, so you can choose a measuring sensor or a plain set-point switch as the job requires, compare mounting and materials across brands, and route a fire-rated need to the right one.
