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.
