Pressure gauge guards SPM 903, are suitable to protect sensors against the destroying effects of aggressive liquids. Their design, all in plastic, PTFE coated diaphragm, insure a high chemical resistance.
Pressure from process is transferred to sensor through an incompressible liquid such as oil. Fitting of guard to sensor is done under vacuum.
We accept to fit on our guards, specific pressure sensors from Customers (please ask us before a quotation).
