EMS6 Particulate Emission Monitor

The EMS6 utilises AC Coupled Triboelectric technology. As particles travel through the process they develop a charge. This charge is transferred as the particle passes or impacts the sensing element. The resulting current is amplified, filtered, rectified and further filtered looking only at the AC component. This gives a linear representation of the concentration or mass flow rate of the particles in the gas stream, depending on the chosen scale of calibration. The reason for measuring the AC component is that, compared to the DC component, the electronics are more sensitive. The AC signal is substantially less affected by influences such as amplifier noise and process parameters, which includes the build-up of process dust on the sensing rod. The EMS6 totally filters out any 50 Hz or 60 Hz frequencies related to mains supply. The digital signal is then sent via a data cable to PLC, SCADA or a Connect Network System. The EMS6 linear representation of concentration or mass flow has been validated by independant laboratories. The EMS6 along with ANJ1, ANP1 and Connect software has been tested and certified for monitoring dust emissions according to the "MCERTS" standard.

What It Does:

�
Continuously monitors particulate flow, primarily emissions from process plants.
Capable of being a part of total process monitoring system.
Measures the movement of particulate past the stationary emission monitor.
Output can be interfaced into PLC, SCADA or Connect Network System enabling data to be logged in plant operating system.
Output signal is RS485 Modbus RTU protocol.
Linear representation of mg/m3 (gr/ft3) or mg/s (gr/s). Iso-kinetic sample required for initial calibration.

Benefits:

�
Detects all particles regardless of composition
Very sensitive due to AC coupled technology
Can be a linear representation of either concentration or mass flow rate.
Can monitor extremely small particles eg. galvanising fume (~0.1 �m).
Can be calibrated for large range of concentrations or mass flow rates.
A seamless interface to industry standard PLC, SCADA or Connect Network System.
Easy Installation
Immunity to bridging providing reliable continuous operation.
