INSTALLATION
DANGER
Before installing or removing the P3 pressure transducer, you must check that the line is
not pressurized.
The pressure transducer can be screwed in wherever required. If the transducer is used
to measure dynamic pressure characteristics in liquids, it should be installed with the
pressure connection pointing upward, so that it is not possible for an air cushion to build
up in the measurement tube.
The connecting pin with the M 12 x 1.5 and M 20 x 1.5 threaded connectors for the
P3/3000 bar type, corresponds to DIN 16288.
Notice
When tightening, the wrench (27 a.f.) must only be put to the flat of the mounting flange
and not to the housing or to the cable entry. The permissible tightening torque is 30 NVm.
Pay particular attention to the sealing on the thread of the connecting pin. The pressure
medium and the respective conditions of installation for the individual case will deter
mine which type of sealing is suitable. Some of the sealing options are shown below.
Fig. 6.1
The USIT ring U 12.7 x 20 x 1.5 belongs to the accessories supplied with the P3
transducer up to 500 bar full scale value. For a perfect seal, the bearing
surfaces must be mostly flat and without marks. The pin hole must not have
spot‐facing and should only be slightly deburred, as the pressure of the
measurement medium pushes the lips of the seal against the transducer and
the bearing surface.
