Continuous Beta in Air Monitor – CAM-B
CAM-B is an airborne beta particle monitoring unit, for activity level in working area.
- Very Compact, Lightweight, Portable
- Extremely low background < 50 CPM @0.02mGy/h field
- High counting efficiency - 13%
- Low noise - 70 dB
- Digital Air Flow rate
- Innovative Filter assembly & shielding
- Ready for SCADA Integration
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
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
