1.0 Installation and Commissioning
The pressure tapping points should be prepared in accordance with the indications given for the sockets.
For more details, see e.g. rule VDE/VDI 3512, sheet3. Suitable for sealing are sealing washers to DIN 16258.
The correct tightening torque is depending on material and shape of the used seal. It should not exeed 80 Nm.
The mounting position should not be subject to strong vibration and radiation heat.The mounting position
which the transmitter is adjusted for, is indicated on the rating plate. If the device is installed in a different
position, the zero point may be offset. The transmitters are immediatly ready for service after the pressure
and electrical connections have been made.
2.0 Wiring
Electrical connection is made by means of plug or shieldes cable with cappillary tube. Precise wiring schemes can
be seen in the drawings. In addition, wiring details and required power supply are given on the rating plate.
Significance of applied terminal designations:
2.1 Current output
output signal: 4 ... 20 mA / 2 wire-system
Power supply: Ub = 7,5 ... 30 V DC
Admissible load: Ra = (Ub - 7,5 V) / 20 mA
3.0 Service and Maintenance
The transmitter described here under is maintenance free. If incorporates no components which have to be
repaired or replaced on the site. Repairs can only be carried out at the factory. Depending on working con-
ditions, the pressure transmitters should be checked about once a year to ensure that they are within their
specifications and be adjusted if necessary.

The connecting cable with capillary must not be pinched or bended to avoid interruption of pressure com-
pesation to ambient pressure.
