Industrial pressure transmitter with
voltage or current output
DescriptionDescription
Technical Data
Features
The pressure probe of series DRTR convert the measured values in
the form of calibrated and temperature compensated standard signal
of 0...10 V or 4...20 mA. The delivery spectrum covers a wide pressure
range from vacuum to 100 bar FS with 12 variants of different measuring
ranges (see table).
Through a precise calibration at 7 measuring points, an outstanding ac
-
curacy and a very low temperature residual error is achieved.
The probes are ideally suitable for measurement of static and dynamic
relative pressure in liquids or gases. Typical areas of application are in
the eld of pneumatics, hydraulics and other industrial applications.
The robust probe housing with enclosure type IP 67 is made of anodised
aluminium and is provided with a 1/4“ internal thread for connection to
the medium.
The electric connection is done with an industrial plug as per DIN 43650.
The model with current signal is connected through a current loop. The
model with voltage output requires an auxiliary supply.
Besides the standard variants, customer specic models for absolute
pressure with other type of calibration, ratio metric voltage output and
also with digital output signal are also available. Further information on
OEM-models can be obtained on request!
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 .
