Hydraulic units
What are the challenges in monitoring the hydraulic unit?
- Control of particle contamination to prevent damage to valves, actuators and pumps.
- Control of tank water contamination due to steam condensation and process problems.
- Control of pressure, flow and temperature of the pressurised fluid.

How to monitor oil contamination?
In principle, water is an undesirable element in hydraulic fluids and lubricants. A high concentration of water can seriously affect operation or cause damage. The LDH100 sensor measures the relative humidity in the oil in the range of 0...100% by means of a capacitive sensing element. In addition to relative humidity, the sensor transmits the fluid temperature as an analogue signal. The LDP100 optical particle monitor measures the purity or contamination of hydraulic oils according to standards ISO 4406 and ISO 6149-2.
Pressure, flow and temperature monitoring
To ensure a fully functional process, the oil should be at the pressure and temperature required by the system. The flow rate can indicate wear issues in pumps and leaks in piping.
How to monitor the condition of hydraulic pumps?
The VSE diagnostic electronics monitor the vibration of the electric drive motor and hydraulic pump. This system enables the detection of bearing damage, electrical defects, damages in internal pump components, as well as cavitation and mechanical component wear.
