Operating instructions for EE310 Humidity / Temperature Transmitter
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.

Installation of the EE310-T10 probe directly into the process
3.4 Installation of the probe with ball valve set
The ball valve set allows for installation and removal of the probe without process interruption.
For mounting into a duct, the ball valve shall be installed perpendicular to the flow direction.
The two metal sealing rings (see
Fig. 13 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
(±72 °F)
from the regular
temperature during normal operation.
Installation of the probe
(see
Fig. 13 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.
