BCM-MS, BCM-LS
3.2 Installation
The sensor is a screw-in sensor with ¾" thread. The level sensor must be screwed vertically into application tank from above, the
BCM-MS200 can either be installed sideways in the tank or in a flow pipe using a line adapter.
Condition monitoring requires the bottom 5 cm of the sensor to be bathed in oil for Level 200/375/615. The probe head of the
BCM-MS200 should always be in oil. Maximum pressure and temperature ratings should generally be observed in the sensor
placement.
Screw the sensor into a prepared mount inside the tank. A profiled sealing ring seals this from the oil side. To ensure proper
sealing, the seal face of the sensor mount should be specially prepared and have a maximum roughness value of R
max
= 16. The
tightening torque for the sensor is 45 Nm ±4.5 Nm.

To ensure proper function, please observe the following guidelines related to sensor mounting position and location.
– To analyse an oil volume characteristic of the oil condition, the sensor should not be immediately in the oil sump of the tank.
– For tank top installation, it will preferably be mounted near the return or flushing pipe.
– Ensure the sensor is fully covered in oil regardless of the system operating situation. Particularly note the varying oil volume
of the tank or potential inclination. Avoid foam in the tank.
– When installing the return or flushing pipe, please note the flushing pipe must not run dry in any operating situation.
– To avoid thermal factors as much as possible, the sensor should not be installed in the immediate vicinity of hot components
and parts (e.g. motor).
– Varying oil temperatures are required to enable converting the characteristics to a reference temperature. The greater the
temperature fluctuations, the quicker the temperature gradient can be determined.
