Differential Pressure Meter DM 3
differential pressure meter for overpressure, differential pressure and negative pressure, ability to mount pitot tube, analog output, average value calculation 

The differential pressure meter DM3 series is designed to accurately measure the differential pressure of gases in a range of -2000 mbar ... +2000 mbar, respectively, 1.5 ... 180 m / s (depending on model). The differential pressure meter can measure positive or negative pressure (vacuum) and differential pressure. Thanks to its high overload safety system, this differential pressure meter can be used in static pressure systems up to twice the value of full scale. meter offers even the possibility of indicating an average value with ranging pressures. The display resolution changes the last digit according to the parameter. The automatic switch-off allows a long battery life for the differential pressure meter. This differential pressure meter can be connected via the analog output to a display system or data logger. The value of the analog output of the differential pressure meter is directed by the resolution selected from 0 to 2 V, both for a fine resolution and for a coarse resolution. The correction of the zero is simple, it requires the touch of a key on the differential pressure meter. If you have any questions about the differential pressure meter, see the technical data below or call us:+44 ( 0 ) 2380 98703 0. Our engineers and technicians will advice you on the differential pressure meter, and of course, on the other products in the field of regulation and control, measuring instruments and scales or balances.
