Intelligent Exhaust Air Sensor: Type AL 2000

System description:

The AL 2000 system is for monitoring of radioactive gases in the exhaust air.

Within the all-side shielding is a detection system that detects the background effect of the measuring station as well as radioactive air samples. A pump transports a part of the exhaust air with a continuous flow through the measuring station. All detectors are sending impulses, whose handling does an electronically counting-mechanism. The measurment values are relayed to a PC over a bus-system. This PC performs the archiving and data-processing, controls and monitors all processes and parameters at one time.
