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 undened additives .
