Description
Model Simple to use, yet powerful enough to detect low level nuclear contamination, enables Model PSAM-1 to be used in applications like Nuclear Contamination in Steel. Model PSAM-1 contains a main readout unit with two plastic scintillator detectors coupled through two composite cables to the main readout unit. The signals generated by the detectors are continuously monitored by the microcontroller based circuitry used in the readout unit. Two 7 segment LED displays on the readout unit indicate the instantaneous values of counts (proportional to the incident nuclear radiation) from the two detectors. Audio and Visual Alarm indicators are turned on as soon as the set alarm limit is crossed by the incident radiation. Setting up of Alarm Level and Detection Time (Integration Time) is done through the keyboard and the 16×2 line LCD display. This LCD is also used for indicating various messages and menus.


Typical Applications
- Area Monitoring
- Contamination Measurement in Steel or any material
- Portal Monitor
- Gate Monitor
