Probe Installation With Ball Valve - E+E Elektronik Modbus MOP301 User Manual

Replace the metal sealing ring (see Fig. 5) by a new one every time before re-installing the probe.
Probe installation steps
■ Close both shut-off 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.
■
Strictly Observe 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.

Probe Installation with Ball Valve

Ball valve HA050101, HA050104
The ball valve allows for installation and removal of the probe without process interruption. For mounting
into the pipe, the ball valve shall be installed perpendicular to the flow direction.
The two metal sealing rings (see Fig. 6) shall be replaced every time prior to re-installing the probe.
The temperature during probe installation may deviate by max. ±40 °C
during normal operation.
Probe installation steps (see Fig. 6)
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.
■
Strictly observe the tightening torque. A torque lower than 30 Nm results in a smaller retention force of the
clamping sleeve. As a result, there is the risk that the sensing probe will suddenly be ejected 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.
