MCS Features
The MetallicContamination Sensor MCS is a stationary sensor for continuous
monitoring of contamination of fluids – especially lubrication fluids – with metallic
particles.
With appropriate system knowledge of the monitored system, damage resulting in
detectable metallic particles can be discovered early.
The MCS uses digital signal processing to distinguish between ferromagnetic (Fe)
and non-ferromagnetic (nFe) particles.
Particle results are signaled via two switching outputs. In the factory setting (default
values), the ferromagnetic (Fe) particles are output via the first switching output and
the non-ferromagnetic (nFe) particles via the second switching output. It is possible
to make a switch in the menu so that the first switching output is used for the total
particles (Fe and nFe) and second switch output is used as a "device ready signal".
(For this, see also the chapter Using switching output.)
In addition, the MCS has serial communication interfaces with which connection to
superordinate monitoring systems is possible.
The MCS is intended for incorporation in low-pressure circuits and test benches.
The flow rate through the sensor must be within the limits that hold for the respective
type (see “Technical data”).
The MCS is approved for a maximum operating pressure of 20 bar.
Functional principle
Within the MCS, a high-frequency magnetic field is generated using a coil system.
Two sensor coils detect changes in the field strength of this magnetic field.
Upon entry into this magnetic field of a:
ferromagnetic (Fe) particle, the field strength increases depending on the size of
the particle.
non-ferromagnetic (nFe) particle, the field strength decreases depending on the
size of the particle.
If a prespecified limit is exceeded, a particle event is signaled.
The output signal at the switching output is always the same and provides no
information about the size of the particle.
Using the serial interfaces (RS 485 or HSI) makes it possible to evaluate appropriate
particle size classes.
