Description

  This compact version of Switzer 600 Series Pressure Switches using components of high reliability is specifically designed for OEMs such as Fire fighting, Boilers, Power Plants, SPMs.

  The sensing Stainless Steel Diaphragm is welded to a Stainless Steel housing mounted external to the weatherproof instrument housing.

  The mechanical movements are restricted to absolute minimum using a diaphragm which ensures long term stability.

  The instrument is in Pressure Die Cast Aluminium housing which is best suited for harsh and outdoor installations.

  The sensing element and wetted part of 316 Stainless Steel is compatible for use in process applications with air, gas, water, steam, oil and other chemicals.
