Measuring principle

UE explosion-proof temperature switch have mechanical temperature switch and the electronic temperature switch,UE explosion-proof mechanical temperature switch use the principle of thermal expansion of a fluid to cause displacement of a bellows, diaphragm, bourdon tube, or piston to open or close a set of contacts. Fluid system based temperature switches can be connected to a remote fluid containing bulb by a capillary tube, allowing the switch element to be remote from the sensing bulb.
UE explosion-proof electronic temperature switch comes with a Pt100 platinum sensor, sensor tip; which in relation to the temperature changes its electrical resistance. The electronics of the temperature switch alters the resistance in a clear electronic signal (4..20mA analogue signal).
The currently measured temperature would be displayed on the switch display and can also be released as an 4..20mA analogue signal to external devices and systems.
A temperature switch comes with SPDT-outputs ,4-20mA,The outputs switch off when the temperature exceeds the pre-set values, as the case may be.

Application guidelines

Here are just a few applications:
.Pumps and compressors 每 start/stop, optimizing, shutdown, staging
.Lubricating oil monitoring 每 sump temperature,bearing pressure, predictive maintenance
.Hydraulic oil pressure 每 high pressure monitoring, emergency shutdown, ram cycling
.Filter monitoring 每 automatic backwash, clog and change indication, proving flow
.Safety systems 每 safety integrity levels 1 & 2, alarm and shutdown, local switching, fast response time
.Plant upgrades 每 power and wastewater plant upgrades
