4.3 Probe Mounting
The probe can be installed in applications such as oil storages with almost non-moving oil or as well in circulation
pipes with moving oil.
NOTICE
In moving oil, the mechanical stress on the probe is minimized by only placing the filter cap into the flow. In
systems with mechanical oil contaminants the sensor may get installed only after an appropiate filter.
4.4 Mounting Pressure Tight Probe
WARNING
General safety instructions for installation
The installation, commissioning and operation of the EE360 may be performed by qualified staff only. Special
attention shall be paid to the correct installation of the probe into the process. In case of inappropriate
installation there is the risk for the probe to be suddenly expulsed due to the pressure in the process.
Bending over the sensing probe should be avoided under any circumstances!
Make sure that the surface of the probe is not damaged during installation. A damaged probe surface may
lead to damaged seals and consequently to leakage and pressure loss.
The probe is rated with leakage rate B according to EN12266-1.
4.4.1. Installation of the Probe Directly in the Process
NOTICE
For direct probe installation shut-off valves shall be placed on both sides of the probe insert (see Fig. 7
Installation of the EE360 probe directly into the process). 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 installation may deviate by
max. ±40 °C (±72 °F) from the regular temperature during normal operation.
Replace the metal sealing ring (see Fig. 7 ) by a new one every time before re-installing the probe.
Probe installation steps
1.
Close both shut-off valves.
2.
Place the sensor probe into the probe insert and adjust the immersion depth.
3.
Tighten the lock nut with a torque of 30 Nm.
4.
Open the shut-off valves.
WARNING
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.
