Picture 11: Connection of a metal particle counter
One Peakanalyzer can drive up to 4 metal particle counter. The 2 channel counter input
terminal of type EL1512 is used for this application. The first terminal of EL1512 measures the
counter impulses at the clamps C-01 and C-02. A possibly second EL1512 terminal provides
the inputs C-03 and C-04. Parallel to the counting functionality a self-test signal of the metal
particle counter can be recorded and analyzed. These digital input signals are then connected
to the digital input channels DI-02, DI-03, DI-04 or DI-05. Furthermore the Peakanalyzer
provides the supply voltage of 24 V
DC
for the metal particle counter.
Picture 11 shows examplary the connection of a MetalSCAN sensor of the series MS3000 of
the company momac. There the impulse of the particle counter is connected to the overvoltage
protection clamp 2-1. The result of the Built-in Test (BIT) is connected to the overvoltage
