3.4.2 Installing the Probe
General safety instructions for installation using pressure-
tight movable screw connections
As the sensing probe can be exposed to very high pressures in the
measuring environment, there is a risk of sudden, unintentional
expulsion of the probe during or after improper installation. Special
care should therefore be taken when working on or in the vicinity of the
sensing probe. Do not, under any circumstances, bend directly over the
probe.
When installing the sensor probe, be careful not to damage the surface
of the sensing probe.
This could damage the seals (resulting in leakage and pressure loss)
or cause problems when removing the probe (may get stuck).
Before installing the sensing probe, make sure it is free from any
impurities such as grease or dirt.
Installing the probe
There should be a shut-off valve on both sides of the probe insert when
installing the probe. This makes it easy to remove the sensor for
maintenance and calibration.
1. Install the probe with the shut-off valves closed.
2. Insert the sensor probe into the process.
3. To ensure the probe is installed securely, the lock nut must be
tightened to a specified torque of 10 Nm.
If no torque spanner is available, tighten the lock nut by hand as far
as possible and then turn it a further ~ 90° with an appropriate
open-ended spanner.
An inadequate torque results in a low tension force (fixing force)
on the clamping sleeve. This brings with it a risk of injury due to
sudden expulsion of the sensing probe. An excessive torque can
lead to permanent deformation of the clamping sleeve and
sensing probe, making removal and re-installation more difficult
or even impossible.
