3.1

Mechanical Installation

Before starting operation, check the process connection carefully for leaks under pressure.
You can use the device in any mounting position. Normally the transmitter is adjusted for a
vertical mounting position. A different mounting position in combination with a small nomi-
nal range might cause a zero point offset. In this case a zero point adjustment might be
necessary.
Use gaskets, if required, that are suitable for the process connection and resistant to the
media.
Use new gaskets for each installation. We recommend the use of aluminium gaskets (A 27
x 32 as per DIN 7603), which you can order directly from us as an accessory.
Fit the pressure transmitter using four flange screws, as shown on the drilling diagram, and
tighten them gradually crosswise. Max. tightening torque: 60 Nm (slightly oiled).
During installation of the device, attention has to be paid to the diaphragms not being
damaged by the medium being measured. This is particularly important in the case of co-
agulating media that can have deforming influence on the diaphragms when they get cold.
Do not insulate the temperature coupler (tubular shank under the transmitter), as this
would reduce its decoupling effect.

Electrical Connection

Complete the mechanical installation before you connect the device electrically.
Set up all electrical connections while the voltage supply is switched off.

Operation

During operation, take care that the device remains within its intended pressure and tem-
perature ranges. No other monitoring is necessary.
