ENVEA - Model PCME DM 210 -Filter Dust / Leak Monitors
The PCME DM 210 comprises a single compact sensor design with integrated user interface for reliable and robust particulate monitoring for all types of industrial processes. Additional functionality allows the instrument to measure defined units (mg/m³) with QA checks if required by the Process Operator or Regulator.
The instrument benefits from PCME’s unique ElectroDynamic™ Probe Electrification technology and advanced features enabling configuration for all types of bag filters irrespective of cleaning sequence.
- High quality leak response with sufficient dynamic range and time response to track emissions from single and multi-compartment pulse cleaned bag filters
- Optional system self-checks to validate measurement integrity including automatic Zero and Span checking
- ATEX / IECEx category 1/2/3 option for Dust Zones 20, 21, 22
- Insulated sensor rod option for unmatched performance in applications where water condensation is likely
- 0-100% or user scalable display in mg/m³, of assistance to plant operators wishing to manually scale the display to an approximate known dust level
The PCME DM 210 provides additional powerful bag leak capability based on the following standard features:
Bag leak monitoring performance
- High quality leak response with sufficient dynamic range and time response to track emissions from single and multi-compartment pulse cleaned bag filters
- Instrument drift and minimum detection level below 0.1 mg/m³ with leak monitoring to 500 mg/m³
- Convenient bag leak output 4-20 mA range scaled 0-100%
- Option for scaling in mg/m³
Designed for practical bag filter issues
- Inbuilt surge protection to counter effects of indirect lightning
- Market pulse from bag cleaning cycle option to identify leaking bag rows
- Powered directly from mains power supply, 100-240V AC 50/60 Hz (32mA) or 24V DC (300mA)
Powerful user Interface
- Instrument set-up via internal keypad and display
- Intuitive multi-level user interface (user set-up, engineering set-up) with password protection
- Tri-colour status LED: power, fault alarms
- Sensor LED for self-check status (where option supplied)
- Remote set-up via optional PC software (Device Set)
