Description of the FCU
The FCU FluidControl Unit can determine the solid particle contamination of mineral
oils on a continuous basis.
With the FCU, it is possible to record, save and display the particle numbers for six
particle sizes and the cleanliness class completely automatically during continuous
operation in accordance with NAS 1638 and/or SAE AS4059 or ISO 4406.
The measured values can be printed out online in the form of either tables or graphs
by means of the built-in printer or sent via serial interface to a PC or a central
display unit for visualization purposes there.
Filter units can for example be actuated via relay outputs.
For input and output functions, the FCU possesses a keyboard, an LCD (Liquid
Crystal Display), a dot-matrix printer, control relay outputs and a serial data interface
The FCU possesses a mini measurement port (System 1620) as an input for
connection with the hydraulic unit, as well as a DN 7 plug nipple a a return flow.
A flow rate control valve is available for setting the measurement flow rate. This is
protected against larger particle contamination by an upstream filter.
The FCU has a rechargeable battery for ~ 5 hours of operation independent of the
mains network.
The FCU has a measured value memory for up to 3000 measured values, which are
stored in the form of logs (maximum of 100).
