5.2  Installation location / environment

• 

Install the unit according to the specification (max. 50 bar).

• 

Do not install the unit in the direct vicinity of hot components (e.g. motors) to 

avoid thermal effects�

•  The installation position shall be representative for the condition of the oil�
•  The unit shall be installed at a point where the medium is sufficiently mixed�
•  The probe must be completely covered by the measured medium and be below 

the minimum oil level in any operating situation� Please note in particular the 

level variations in the tank or a possible tilted position (fig. 2 on the next page).

•  Preferred location in hydraulic circuits: in the tank close to the return pipe�
•  In case of gears with forced rinsing the unit may also be installed in the rinse 

pipe�

•  If the unit is installed in a return pipe or a rinse pipe: make sure that the pipe 

does not run dry in any operating situation�

•  If the oil in the tank is not sufficiently mixed, it is possible that free water settles 

on the bottom� In this case two layers form: the upper one consists of oil, the 

lower one of free water� Should the measurements be made in the upper level, 

the horizontal installation according to number 6 in figure 1 on the next page 

is recommended� Should the measurement be made in the lower layer, the 

vertical installation according to number 5 is recommended�

•  When the sensor is installed vertically into the bottom make sure that the 

sensor is above the decoction level� Otherwise measurement may be affected 

by build-up of dirt�

• 

The max. installation angle (fig. 2 on the next page, position number 7) 

depends on the installation height and the min� level� The probe must again be 

completely covered by the measured medium and be below the minimum oil 

level in any operating situation�
