Application and performance features

Versatile, robust measuring device with glycerine filling
Housing with flare ring made of stainless steel, sight glass made of polycarbonate, pressure connection plug made of copper alloy
Can be easily attached to control or display panels from the front using screws or rivets
Good pointer readability even with mechanical vibrations at the measuring point
Increased service life with pulsating pressure fluctuations (measuring element, measuring mechanism)
Pressure measurement of gaseous, low-viscosity and non-crystallizing media that do not attack the copper alloy
Display ranges according to EN 837-1 between -1 bar and 600 bar
Accuracy class 1.6 according to EN 837-1
