SOR 141-N Differential Pressure Switch

Feature & Principle

It is SOR 141 series mechanical differential pressure switch. It adopts diaphragm sensing structure, detects pressure difference between high pressure and low pressure ports. When differential pressure reaches the preset value, it triggers snap-action micro switch to realize on-off signal output. The set value can be adjusted on site without power supply. Stable repeatability, small dead band, some versions with nuclear 1E qualification, suitable for low differential pressure monitoring of minimum flow bypass and pipeline.
