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.

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.

All communication is encrypted.

Measuring Range: programmable linear ranges i.e. 0-5000, 0-10000, 0-50000 & 0-100000 CPM.
High Air flow rate: 5 to 150 LPM, user settable.
Accuracy: ± 10% of reading throughout the range with excellent stability.
2 MB internal memory to store the readings such as alarm, HV fail, Link status etc.
EHT Voltage: 100-700V dc.
Communication: GPRS OR Zigbee wireless.
Power: 230V AC ± 10% 50Hz. .
Time Constant: 0 to 60 sec depending upon count rate. (0= dynamic time constant). .
Display update rate: 1second.
Graphical 128 x 64 LCD display.
6-digit 7-segment LED Display.
Diagnosis & Indication of detector fail, HV fail; pump fail.
Output: 4 - 20mA or 0-5V.
Contact output for Alarm indication.
Contact inputs for alarm acknowledge and reset.
Detector housing and Air sampler filter holder assembly: SS 304 L.
