Power Units in Modular Design with Condition Monitoring

Application
Power units with condition monitoring are used in hydraulic systems to increase the availability of machines and systems and to reduce maintenance and repair costs.

Description
Continuous condition monitoring assumes that many machine failures due to component wear are announced in advance. Since it is not possible to measure the wear of all hydraulic components, the hydraulic oil is a good indicator.
An oil condition sensor collects the following fluid data:

● Electrical conductivity
changes when metal particles are introduced due to wear on pumps, valves and cylinders.

● Relative dielectric constant
is a measure of the permeability of electric fields. It is used to monitor the oil ageing process to determine whether oil has been refilled or whether other liquids and foreign particles have penetrated.

● Degree of saturation
is a measure of the amount of water in the oil.

● Oil temperature
especially their modification over a longer period of time. Indicates the load on the system and possible wear of the components.

Also integrated:
● Level sensor
for the exact measurement of the oil level. Changes e.g. in case of leakages.
● Oil filter control
with electrical contamination indicator.
