Overview
The EM 70DGX is a high accuracy continuous particulate monitor with advanced filter leak detection capabilities and optional
internal self checks to automate EPA, ASTM and ISO instrument calibration requirements. It enables continuous real-time
and averaged analysis and recording of particulate emissions as well as early warning leak alarming for process control
and EPA compliance. It is designed for fabric filters, cyclones and process particulate flow monitoring.
The EM 70DGX has all the ease-of-use and renowned reliability of the popular EM 30LGX plus several important requirements
for EPA regulations such as MACT. These additional features are equally beneficial for critical process control applications.
- High resolution 4-20mA for low level analysis and recording
- Short and long term data averaging
- Wide range of adjustments & I/O
- Optional internal automatic zero and span checking system
- Optional fieldbus communications and PC analysis/reporting software

Principle of Operation
The EM 70DGX employs a field-proven combination of charge induction and protected-probe technologies invented by
FilterSense. As particles flow near and around the probe, a minute current is induced. A DSP processes the signal
into an absolute output that is linear to mass flow. A protective layer over the probe works in combination with inductionsensing to ensure reliable operation with conductive particulate, moist powders, corrosive gases and particulate buildup.
Maintenance is minimal and there is no need for an air purge. For durability the sensors are passive and free of electronics.
For safe, easy access and to facilitate EPA QA checks, the control unit and electronics are remote.
