Brand: Orion Instruments

MZ Series pressure switches have been designed for applications that require cost effective outdoor mounting in aggressive environments. 

The tough polycarbonate cover, fitted on a stainless steel base, retained by SS screws offers excellent resistance to corrosion, and also allows a view of the integral scale and working of the pressure switch. 

The reliable microswitch offers narrow dead band, switching values, which have excellent repeatability. 

By using appropriate capsules and wetted parts, MZ series pressure switches can be used for thousands of applications.
