Industrial pressure transmitter DRTR-AL
for measurement of absolute pressure
DescriptionDescription
Technical Data
Features
The pressure sensor of the series DRTR-AL transmitts the measured
value in the form of a calibrated and temperature compensated standard
signal of 0…10 V or 4…20 mA. The product range covers 6 different
measuring variants of the pressure range from vacuum to 50 bar Full
Scale (FS)(See table).
With the precise calibration of 7 measurement points at 3 different tem
-
peratures, excellent precision and a very low temperature residual error
is achieved.
The sensors are ideal for measuring the static and dynamic absolute
pressure in liquids or gases.
Typical applications are in the eld of pneumatics, hydraulics and in
-
dustrial applications. The robust sensor housing with IP65 is made of
anodized aluminum and has a G¼“ media port.
The electrical connection is an industrial plug according to DIN 43650.
The electrical power signal is supplied via the current loop, and the ver
-
sion with voltage output requires a separate unit for power supply.
In addition to the versions with 4...20 mA and 0...10 V variants with di
-
gital output signal, stainless steel case, and relative pressure versions
are also available.
In general the B+B pressure sensors are medium resistant. However
we recommend to prove the media compatibility with critical mediums
such as electroplating applications (iron trichloride) or oils with unde-
ned additives .
