Mechanical installation

P2V
CAUTION
Before installing the P2V, check that the threaded con­
nector and the thread in its mating component are sound
and without burrs. The parts must be easy to join
together.
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
not possible for an air cushion to build up in the measur­
ing tube that could, for example, heat up unacceptably in
the event of adiabatic effects as a result of dynamic
loads.
Transducers with measuring ranges of 100 ... 2000 bar
are connected with their G1/4" external thread pressure
connection. A 58° tapered seal made of 1.4301 corro­
sion-resistant material is supplied for this purpose.
The G1/4" pressure connection thread with the tapered
seal is suitable for the usual 17 mm hole depth and a
drilled diameter of 4 mm (with a margin of between 0 and
0.5x45°, also see Specifications).
The tapered seal is fixed accurately and securely in the
measuring aperture of the transducer by means of the
small, stainless steel retaining spring that is among the
items supplied for each seal. The device can thus be fit­
ted and sealed extremely efficiently.
Transducers with measuring ranges of 3000 bar and
higher are connected with their M16x1.5 external thread
