Introduction

Principle & Structure

The built-in plunger is connected with the precision spring. When the pressure changes, the spring expansion and contraction will change accordingly. When the pressure reaches the set value, the preset mechanical structure will be triggered and a switch signal will be sent. The controller uses a leak-free piston sensor.

application

The gas-liquid dual-purpose type can be used for compressed air containing oil mist, other oil-containing mist gases and hydraulic oil that have no corrosive effect on pressure sensor materials, water-oil emulsions and neutral liquid media with good lubricating properties.
