DS Series differential pressure switch from FISCHER supplied by Alvi Technologies is designed for water, oil and non-aggressive gases.  

The differential pressure switch is based on a rugged, reliable membrane sensing system. It is suitable for detecting vacuum, over pressure and differential pressure.  

The force moves the membrane in one direction against the measuring range spring. A plunger fitted to the membrane operates a micro-switch to operate the switch point. There is a dial to adjust the set-point.  

The differential pressure switch is overload protected giving high repeatability with long life  

The stock standard adjustable pressure range is 0.16 – 1.6 bar and the maximum operating pressure is 16 bar. It is designed to operate at -10 to +70°C with maximum medium temperature of 80°C.  

The membrane is made of ANSI 301 stainless steel with G1/8 female pressure connection. The switch point is adjustable in 0—100% of the range.  

The differential pressure switch also comes with ATEX Hazardous Area Compliance and IP 65 protection class. The micro-switch is rated 3 A, 250 V.  

The differential pressure switch finds wide application in heavy process engineering industries.
