15. Important tips at a glance

• For hydraulic applications, we recommend that the sensor is fitted in a vertical position with the

electrical connector pointing downwards.

• When installing the sensor, ensure that it is totally immersed in the fluid and that the fluid can

circulate freely through the sensor.

• Ensure there is constant flow and prevent the formation of air bubbles. With standing oil,

variations in measurement may increase.

• In principle the HYDACLab

®

must only be supplied with voltage if full flow is guaranteed.

In other words, disconnect the HYDACLab

®

from the supply voltage as soon as the

system is switched off, stops operating or if the flow is interrupted for a significant period.

• Ensure that the operating conditions are typical during the referencing phase (learning phase)

i.e. the whole range of conditions relevant to operation are included.

• The start of the learning phase begins as soon as the HYDACLab

®

is connected to the voltage

supply, and as soon as the temperature exceeds 25°C for the first time.

• During the referencing phase, avoid mixing fluids and ageing fluids.
• In the event of oil change or serious alteration in the ambient conditions, the unit should be

reset

• When installing without the mounting block ZBM 21 or ZBM 23 make particularly sure

that the flow of fluid is not impaired by the installation. A minimum distance of 10 mm
must be maintained between the front end of the sensor head and the opposite
pipe/housing wall.
