Installation
4.1. General installation instructions for sensors
idOil sensors can be installed in zone 0 explosive atmospheres. Do not remove the sensor
markings from the cables or sensor frames.
Read Section
General safety instructions
before installation.
Check the correct installation depth of the sensor in the instructions of the separator in
question.
For example, sensors can be installed suspended from their cable (see next figure). Leave
a sufficient length of the sensor or extension cable coiled inside the service well, so that
you can easily lift the sensor out for inspection and cleaning.

4.2. Installing the idOil-OIL sensor
The sensor must be submerged at the desired installation depth when the liquid is at the
separator’s standard liquid level (L).
The exact installation depth depends on the following:
separator type
separator shape
volume and height of the separator’s oil compartment
The sensor must always be immersed in liquid. The alarm is activated when the lower
surface of the oil layer reaches the alarm switching point (S), i.e. when the sensor’s
measuring electrode is covered in oil.
The sensor activates the alarm when it is in contact with air. For this reason, the separator
must always be filled with water after draining.
