Dial pressure gauge PGT02

Bourdon tubewith electrical contactnon-contact

Pressure gauges with output signal combine the advantages of the analogue indication of a mechanical pressure gauge, needing no external power, with the electrical output signal of a pressure transmitter. These hybrid instruments are available with all commonly used electrical signals. The sensor works in a non-contact way, without any influence on the measuring signal. Many of the instruments can be delivered in accordance with ATEX with an Ex-i intrinsically safe ignition protection type. Applications For monitoring of water pressure changes in heating plants (wall-type boilers, free-standing boilers) Special Features Non-contact sensor (wear-free) Case made of plastic with snap-fit cams for panel mounting Nominal size 40 Scale ranges 0 ... 2.5 bar to 0 ... 10 bar Output signal 0.5 ... 4.5 V ratiometric Descriptions Design EN 837-1 Nominal size in mm 40 Accuracy class 2.5 Scale ranges 0 ... 2.5 to 0 ... 10 bar or all other equivalent vacuum or combined pressure and vacuum ranges Pressure limitation Steady: 3/4 x full scale value Fluctuating: 2/3 x full scale value Short time: Full scale value
