Differential pressure gauges with diaphragm element and alarm contacts

Service intended

Suitable for gaseous and liquid, non-crystallizing media that will not obstruct the pressure system. Scale range must be selected in consideration of the highest static pressure applied. These alarm contacts are intended to make or break an electrical control circuit relative to the position of the instruments pointer.The functions of the different contacts may be chosen depending on application. Points of contact actuation are adjustable over the full extension of the scale graduation. For points with high, dynamic load, fast load alternation and pressure peaks or vibration we recommend a special oil filled type (only available with round case model).
