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.
