Mechanically adjustable pressure switch-P20

Product introduction

The built-in piston is connected to the precision spring, and when the pressure changes, the spring expansion will change accordingly. When the pressure reaches the set value, the
preset mechanical structure will be triggered and the switch signal will be sent.
Compact structure, solenoid valve standard plug, wiring is extremely convenient, wide measurement range (0-400bar).
High overload capacity (up to 1230bar), high repeatability, normally open or normally closed contact, gold-plated contact, large contact capacity. Can be used for water, oil, gas pressure measurement.
