Idoil-Oil Oil Sensor; Idoil-Slu Sludge Sensor - Labkotec idOil Solar Installation And Operating Instructions Manual

Installation and Operating Instructions | idOil Solar
3.3.3.

idOil-OIL Oil Sensor

The idOil-OIL sensor can be installed in a zone 0, 1 or 2 potentially explosive (Ex) area,
e.g. oil separator.
3.3.4.

idOil-SLU Sludge Sensor

idOIL-SLU sensor can be installed in zone 0, 1, or 2 potentially explosive atmospheres.
The idOil-OIL oil sensor is installed into the light liquid storage
chamber and gives an alarm when the chamber is filled to a
pre-determined level. The sensor is normally fully immersed in
water.
Insert the sensor into the separator using the access point
provided by the separator manufacturer. The sensor gives an
alarm, at the earliest when the upper electrode is in oil, and at
the latest when the sensor is totally immersed in a non-
conductive liquid . In other words, it is totally separated from
the water.
The sensor can be mounted suspended by a cable from the
ceiling of the separator. Please check the correct installation
depth from the instructions of the oil separator as well.
The function is based on the measurement of the electrical
conductivity of the surrounding liquid – water conducts
electricity more efficiently than oil.
The idOil-SLU sensor is installed in the separator or tank and it
gives an alarm when sludge reaches the sensor. The sensor is
normally immersed in water.
The idOIL-SLU sensor gives an alarm when there is enough
sand or sludge accumulated between the two heads of the
sensor. When the sludge layer on the bottom of the separator
or settling tank is pretty solid, the correct installation depth can
be adjusted, based on the current level. In the event that the
level is not clear, a trest period of a couple of days may be
useful.
The sensor can be mounted suspended from the ceiling of the
separator by cable. Please refer to the oil separator
instructions for correct installation depth.
The principle of measurement is ultrasonic. When sludge, sand
or other solid particles accumulate between the two sensor
heads, the signal strength weakens, an alarm is given.
