The EMS611 provides continuous, low maintenance, precision measurement of dust (mg/m3(N), Optical Density and Opacity. It is designed for monitoring visible smoke and particulate concentrations in the exhaust gas of industrial combustion or air filtration processes.
Operational path length of 2-50 feet.
The EMS611 dust monitor utilizes dual beam measurement and the highest quality (PS-1 grade) optics to assure accuracy and dependability. Our electronically modulated light source is immune to ambient light and carries an industry leading guaranteed lifetime of 70,000 hours.
Every EMS611 is manufactured to the customer’s site specific requirements and is tested for a minimum of 24 hours on our optical bench. The sensor and reflector are housed in NEMA 4 watertight enclosures and are designed to swing away from air plenum for easy installation and service. Adjustments in alignment are accomplished by utilizing our “Through the Lens” system which includes a 3 point adjustment that is integral to the air plenum. Calibration is accomplished automatically by an adjustable cal timer (1-24 hours) or manually on-line.
Our user friendly controller features 5 selectable displays including a split screen display for Opacity and mg/m3. The output “hold” function is optimal for process control applications which cannot have variations during the automatic calibration process. Communications are accomplished through (2) 4-20 mA outputs as well as RS485 MODBUS.
The service module, located in the stainless steel weather cover, is used to pass signals to and from the transceiver and control unit. It initiates maintenance zero and span cycles and also provides an insertion point for an external current meter in the transceiver to the control unit’s 4-20mA loop. The service module is useful for trouble shooting and eliminates the necessity for a second technician.
Since 1990, companies around the world have relied on EMS to monitor the amount of visible emissions, smoke, dust or opacity from their process. It is our hope that you will give us the opportunity to work with you on your next project. We are confident that you will be satisfied with the performance and worry free operation of our monitors for years to come.
