EMA30.70 MCS900 SERIES DUST AND PARTICLE MEASUREMENT INSTRUMENTS
EMA30
Overview
Featuring EMA’s virtually maintenance-free particulate flow sensing technology, the EMA30 is the process industries most reliable baghouse monitor, filter leak detector and cyclone overflow detector. It is also easy to operate.
Simply apply power and begin assessing filter condition. For alarm setup the display provides both a logarithmic analog bar graph and an absolute digital readout. The log scale enables simultaneous observation of baseline readings and high dynamic peaks caused by filter cleaning cycles which is
essential to set alarms. The digital read out in absolute units ensures correct interpretation of the readings and provides accurate historical comparisons without having to normalize data based on sensitivity or automatic gain settings. Outputs include dual relays and a 4-20mA for PLC connection.
The EMA 30 meets EPA MACT leak detection regulations when configured accordingly. For automatic calibration checks, advanced filter leak analysis/locating systems and particulate CEMs, refer to other EMA models
Features and Benefits
Advanced Induction-Sensing
Ultra Reliable Protected-Probe
Detect Leaks Before Visible Emissions
Prevent the Escape of Valuable Powders
Protect Downstream Equipment
Superior to Traditional Triboelectric
The EMA30 employs a field-proven combination of charge induction and protected-probe technologies invented by EMA. As particles flow near and around the probe, a minute current is induced. A DSP processes the signal into an absolute output relative to particulate flow. A protective layer over the probe works in combination with induction sensing 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

With multi compartment baghouse easily assess and compare compartments using the on-screen logarithmic bar graphs or optional remote FilterWare software. For monitoring mass emission trends in the common outlet a DynaCharge™ processor module can be added to provide the industries most advanced particulate monitoring technology with automatic self checks. For pulse jet filters with fixed cleaning patterns leak locating can be added. (For leak locating with varying cleaning times or patterns refer to EMA B-PAC™ Controls).The MCS 900 offers a full range of fieldbus communications and a wide range of modular relay and analog I/O.
Principle of Operation
The MCS 900 offers several levels of particulate monitoring performance based on charge induction and protected-probetechnologies invented by EMA. As particles flow near and around the probe, a minute current is induced. A DSP processes the signal into an absolute output relative to particulate flow. A protective layer over the probe works in combination with induction-sensing 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.
