Continuous Beta in Air Monitor – CAM-B

CAM-B is an airborne beta particle monitoring unit, for activity level in working area.

How it works

Beta activity indication in CPM or DAC .

Air flow indication and logging with low air flow alarm indication.

Alarm output and Alarm Acknowledge, Reset.

Detector: GM Tube Detector with filter holder-assembly comprising

  • Glass mica End Window type GM tube.
  • A filter paper holder.
  • Dual nozzle Air Suction chamber.
  • Shielding & efficiency

    • 50mm thick lead shield minimizes background gamma count.
    • Shielding effectiveness : Background level with 0.02mGy/Hr field less than 50 CPM.
    • Detection efficiency better than 13% with Sr-90 Beta source.
    • Air sampler collection efficiency better than 99% for 0.3 micron size dust particulates.
    • Reduced noise level <70dB, due to Motor mounted vacuum pump and silencer.

    Always Be Connected

    All communication is encrypted.

    Seamless Communication

    • Multiple units send data to a central data concentrator.
    • communication via Ethernet LAN, RS232 and RS485.

    Configurability

      User can set various parameters like:
    • Time constant.
    • Dead Time.
    • Alarm level.
    • Low Air flow setpoint.
    • Log Interval.

    Technical Specifications
