Compact structure  pressure switch 

 

Description

PS20 is mechanical pressure switch , the working principle and structure is built-in piston connected with precision springs, when pressure changes, the corresponding changes in the spring scale, when the pressure reached set value, can trigger preset mechanical structure and signal switch . Diaphragm and piston type pressure switches featuring the standard design are available off-the-shelf as break contacts, make contacts or changeover contacts, An adjustment screw makes it easy to adjust the switching point on-site. Gold-plated contacts are also available as an option for small switching currents.

 

 

Feature

Compact structure , can be used for the most diverse requirements.

DIN connector design , easy to Wiring and open inside to adjust the range .

Widely measurement range , and high overload pressure .

High repeatedly,

have Gold-plated and large capacity NC/ NO contact .

NC/NO or changeover contact for positive and negative gauge pressure 

 

Application

can be used universally in machine and plant construction

water

oil

air
