PCME Ltd, specialists in the field of particulate and dust emission monitoring instruments, has been awarded the UK patent for its new contamination check for Electrodynamic dust monitors.

As regulatory bodies place heightened importance on the quality assurance associated with Continuous Emission Monitors, this check automatically monitors the conditions of the dust probe insulation and provides a user alarm before any contamination will cause an error in measurement.

This patented contamination check is provided on the DT990 Dust Monitoring Network System which recently received TUV approval according to BImSchV 17 & 27.  It compliments the automatic zero and span checks already provided to verify that the amplification and conditioning of the measured signal is performed within pre-defined tolerances.  The contamination circuit monitors for current or signal leakage across the insulator providing the ultimate proof that the sensor measurement is un-compromised.
