Diaphragm pressure gauges with alarm contacts

Service intended

All gaseous and liquid media. With optional flange connection also for viscous and contaminated media. Suitable for precision measurements at measuring points with very high safety requirements. 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).
