The built-in piston is connected with the spring. When the pressure changes, the expansion and contraction of the spring will change accordingly. When the pressure reaches the set value, the preset mechanical structure will be triggered and a switch signal will be sent.
These compact pressure switches are designed by OEM application. They are ideal for marine valve remote control system of construction machinery and other equipment requiring high voltage resistance. 0.3 - 100BAR (optional set point: piston type set point can be more than 200BAR) The abnormal volume pressure range ratio can be set in the factory or adjusted on site.
