Concept OPL 100S Smoke Density / Opacity Monitoring System

  • Opacity & Optical Density measurement
  • Double pass technology, dual outputs & alarms
  • Push button calibration & testing
  • Total system package and complete range of accessories
  • Optional oxygen sensor output

The Concept OPL 100 unit is designed to measure the density of smoke, dust, mist or fog between a given area. The system is low maintenance, double pass, dual beam transmissometer that consists of a transceiver (transmitter / receiver), and a passive retroreflector module. These components are stack mounted which are then interfaced with the control unit. The transceiver produces an electronically modulated and collimated light beam which is projected across the given area to a retroreflector that returns the beam back to the transceiver where the light beam intensity is measured by a measurement detector (MD). This detector will only measure the modulated light and is not affected by the presence of stray or artificial light.

The only two options available from current technologies for density measurement are Opacity and Optical Density - the Concept OPL 100 offers both.

Testimonials

East Sussex County Council

"I was very impressed with the smoke generators provided by Concept Engineering and feel they could be confidently recommended at our group meetings to other tunnel operators who may be contemplating an emergency exercise.

The reaction of the tunnel environmental control system visibility sensors to the smoke was excellent, not only did the fans cut in but the volume of smoke was such that it immediately tripped a high level alarm which additionally sends a signal in the form of a general alarm to the Sussex Police Headquarters.  Had the smoke been generated by a real incident the alarm would have alerted the Police to the problem in the tunnel probably before a call was made from a tunnel emergency phone."
