T10: Installation Of The Probe - E+E Elektronik EE310 Operation Manual

3.3.6 T10: Installation of the probe (sliding fitting up to 20 bar
The ball valve set allows for installation and removal of the 200 mm
interruption. For mounting into a duct, the ball valve shall be installed perpendicular to the flow direction.
The two metal sealing rings (see Fig. 20 Installation of the probe by utilizing the ball valve set) shall be
replaced every time prior to re-installing the probe.
The temperature during probe installation may deviate by max. ±40 °C
ture during normal operation.
Installation of the probe (see Fig. 20 Installation of the probe by utilizing the ball valve set):
• Install the probe into the ball valve while the ball valve is closed.
• Open the ball valve.
• Slide the probe through the ball valve to the desired immersion depth. Depending on the process
pressure additional tools may be necessary for pushing the probe into the process. Make sure not to
damage the probe and the cable.
• Tighten the lock nut with a torque of 30 Nm.
Observe strictly the tightening torque. A torque lower than 30 Nm results a smaller retention force of the
clamping sleeve. This leads the risk of sudden expulsion of the sensing probe due to the pressure. A
torque higher than 30 Nm may lead to permanent deformation of the clamping sleeve and the sensing
probe. This would make the removal and re-installation of the probe difficult or even impossible.

Removing the probe
• Hold firmly the probe to avoid it being suddenly expulsed when releasing the lock not. May sure nut to
bend and damage the probe cable.
• Loosen slowly the lock nut with a spanner (spanner width 24) only till the probe is pushed out by the
overpressure in the process. Do not completely loosen the lock nut, but only as much as necessary
for the probe to slide.
• After the probe has been pushed out of the process up to the stop, close the ball valve.
• Remove the probe from the ball valve.
Observe the correct positioning of the sealing element 1 before reinstalling the probe.
Replacement of the sealing element
In case of repeated installations and removals the sealing element 1 can might damaged. It can be
replaced by the user.
