PM 1 & PM 1 PRO Dust Emissions Monitor & Leak Detector

PM 1 & PM 1 PRO Series

The PM 1 and PM 1 PRO are single-point/basic functionality dust particulate monitors, employing charge induction sensing for reliable continuous monitoring of dust particulate in stacks, ducts and pipes. Applications include filter leak detection, cyclone overflow and powder flow/no flow.

Principle of Operation

As particles flow near or around the electrically isolated sensing probe, a minute charge is continuously induced into the probe. This charge flows through a measurement circuit to ground. The induced charge signal is digitally analyzed and processed to provide an output that is reasonably linear to mass. The unit of measure is in picoamperes (pA).

PM 1

The PM 1 is the industry’s best value in a basic dust particulate monitors and leak/flow detectors. The engineering and quality greatly exceed comparably priced devices. The PM 1’s low cost justifies monitoring even small nuisance dust collectors.

The PM 1 is available in two versions:

PM 1-A

  • Basic particulate monitor with alarm relay outputs
  • Integral electronics only

PM 1-T

  • Basic particulate 4/20mA transmitter
  • Integral electronics only

PM 1 Features:

DynaCHARGE Technology - Superior reliability over other charge and tribo
Digital Readout, Lockable Keypad - Simple text prompts (no trim pots or blind auto set)
Convenient Loop Check and Alarm Functions - Speeds up and confirms installation

PM 1- PRO

The PM 1 is also available in a PRO version for demanding process conditions and EPA compliance applications.

The PM 1-PRO is the benchmark for reliability and features when it comes to standard dust particulate monitors and leak/flow detectors. A state-of-the-art instrument, the PM 1 PRO is the first loop power particulate monitor with EPA certifiable self-tests and performance.

The PM 1 PRO is available in three versions:

PM 1 PRO-A

  • Advanced, high-performance particulate monitor with alarm relay output
  • Integral or remote electronics
  • Graphical display/keypad

PM 1 PRO-AT

  • Advanced, high-performance particulate monitor with alarm relay outputs and analog output
  • Integral or remote electronics
  • Graphical display/keypad

PM 1 PRO-T

  • Advanced, high-performance particulate 4-20mA transmitter
  • Integral or remote electronic
  • Graphical display/keypad
