PREMASREG® 716x-VA pressure switch for volume flow, differential pressure, filter monitoring and liquid level detection

Our PREMASREG® 716x-VA pressure switch features measuring functions for volume flow, differential pressure, filter monitoring and liquid level detection based on the pressure measured in clean air. The piezo-resistive measuring element guarantees high accuracy within the ranges of 0...1000 Pa and 0...5000 Pa.

Its stainless steel housing meets particularly stringent demands in application areas such as clean rooms, medical engineering and filtration, ventilation and air conditioning ducts, spray booths, large catering kitchens, filter monitoring, and level measurement for frequency converter control.

The pressure switch has a manual zero-point pushbutton and an offset potentiometer for final value correction. Parameter entry is menu-based and is easy to perform using three buttons with the help of the display.


Designed for use in harsh operating environments, the Tyr 2E housing is made of V4A (1.4561) high-grade-stainless steel to provide outstanding corrosion, UV, weathering and temperature resistance.

The rugged metal body with its non-distortion bolted front cover is tested to
IP 69 protection type in compliance with EN 60529. Strong mounting brackets on both sides provide a particularly firm seat. And with a size of 143 x 97 x 61 mm, the metal housing is only insignificantly larger than the plastic version.

The device has a large back-lit three-line display on a hinged fold-out bracket – of course behind a high-impact cover. Optionally, the pressure switch is also available with an opaque stainless steel cover.

The electrical connection can be made with a metal cable gland (M20, including strain relief), or an M12 connector according to EN 61076-2-101 (circular connector with thread locking).

For our pressure measuring devices, the Tyr 2E housing offers two pressure ports with quick connects (standard) for pressure hoses or with threaded fittings (optional) for pressure pipes.

Also available as PREMASREG® 716x in plastic housing (IP 65).
