Broken Bag Detectors

Leak Detection Technology that provides dependable and timely response to any upset condition.

Model EM 30T

The model EM 30T is a reliable particulate emissions monitor and filter leak detector in a 2-wire loop powered transmitter configuration. The loop powered design is ideal for direct connection to PLCs and data loggers.

The model EM 30T is available in a compact 1-piece version and a 2-piece configuration with remote electronics for high temperature or high pressure applications. The 2-piece configuration is also beneficial for baghouse applications where outlet ducts are difficult to access. The base model is designed for general maintenance planning and process protection applications. Optional detection level upgrades enable low level monitoring and early warning filter leak detection.

Adjustable linear or logarithmic output ranges in absolute units enable simple setup without confusing sensitivity and gain settings. A log scale output enables trending both the baseline emissions and the high dynamic peaks that are caused by filter cleaning cycles and developing leaks. Observation of both baseline and peaks is essential to setting proper alarms.

Features & Benefits

  • Simple, Low Cost 2-Wire Installation
  • Prevent Emissions
  • Plan Filter Maintenance
  • Protect Downstream Equipment
  • Keep a Clean Work Place
  • Superior to Traditional Triboelectric

Principle Of Operation

The EM 30T employs a field-proven combination of charge induction and protected-probe technologies. 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 Gasses and Particulate Build Up.

Model EM 70DGX

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. 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 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.

Features and Benefits

  • Automatic Zero and Span Checks
  • High Accuracy Low Level Monitoring
  • Analyze Filter Performance in Real-Time
  • Advanced Sensing Technology
  • Superior to Opacity & Traditional Tribo

Model EM 30LGX

Featuring virtually maintenance-free particulate flow sensing technology, the EM 30LGX 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 EM 30LGX 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 FilterSense 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
