When reworking the screw-in trunnion / mounting
hole, pay particular attention to the centricity of:
- the hole,
- the thread and
- the sealing surface.
Pressure sealing with the standard seal takes place
on the sealing surface and on the front cylindrical
section of the PT (see figures 07).
The sealing surface must be:
- correctly machined
- free from marks and rough edges
6.2 Mounting the Pressure Transducer
Mounting and electrical connection of the PT
must be done by authorised specialists with
EMC training only, following all applicable
regulations, and in pressureless, voltage-
free condition with the machine switched
off.
The machine must be secured against
being switched back on!
ESD sensitive component. Electrostatic
discharge may damage the PT.
Take ESD precautions.
Before mounting the PT, check the screw-in
trunnion / mounting hole carefully. The PT
must only be mounted when the screw-in
trunnion / mounting hole satisfy the require-
ments stipulated in chapter 6.1. Screw-in
trunnion / mounting hole that does not satisfy
these requirements can damage the PT.
For pressure sealing use always the seal that
is delivered with the PT!
To prevent the PT from sticking permanently
at the screw-in trunnion / mounting hole, coat
the thread section of the transducer with high
temperature resistant grease or a suitable
parting agent.
Always use a spanner applied to the
designated hexagon collar when screwing
the PT in and out. Do not apply the tool to the
housing!
