14. 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.

• The sensor once fitted must be completely immersed in the fluid and the fluid must be

able to circulate freely through the sensor.

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

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

• 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 optimization 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 optimization 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.
