3.3.5 T10: Installation of the probe directly in the process with sliding fitting up to 20 bar
(290 psi)
(see
Fig. 19 Installation of the EE310 probe directly into the process)
For direct probe installation into a duct stop valves should be provided on both sides of the probe insert.
This allows the sensor probe to be easily removed for maintenance and calibration.
For direct installation into a pressure chamber make sure that the pressure in the chamber
and the ambient pressure are equal before removing the probe. The temperature during probe installa-
tion may deviate by max. ±40 °C
(±72 °F)
from the regular temperature during normal operation.
Replace the metal sealing ring (see
Fig. 19 Installation of the EE310 probe directly into the process
) by
a new one every time before re-installing the probe.
Probe installation steps
• Close both valves.
• Place the sensor probe into the probe insert and adjust the immersion depth.
• Tighten the lock nut with a torque of 30 Nm.
• Open the valves.
Observe strictly the tightening torque.
A torque lower than 30 Nm results in 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.
