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:  UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703. 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. |
