Пристрій контролю на конвеєрі
- High Sensitivity Conveyor Monitor
- Continuously Screen Moving Parcels or Bags
- Gamma and Neutron Radiation Detection Options
- Fast, Seamless Integration
The TSA CM267 is a stand-alone conveyor monitor which can be positioned on the side or mounted directly above a moving beltway. The CM267 features highly sensitive detection for both gamma and/or neutron radiation.
Designed to continuously screen moving items on a conveyor belt without the need for frequent calibration or maintenance, the TSA CM267 is intended for application in transportation centers where the relatively low energy emissions from 235U and 239Pu are the main concern. The CM267 also detects other radioactive isotopes present in threat materials.
The TSA CM267 high sensitivity conveyor monitor offers reliable operation in variable background environments. This system covers most conveyor belt applications, and can be adapted to meet specific requirements.
Advanced Design Features
The TSA CM267 is a self-contained system housed in a single pillar with the gamma and neutron detectors for ease of installation and maintenance. An alarm output relay is standard which may be AC-coupled to stop or divert the conveyor automatically. The system is equipped with ethernet communications capability for integration with the operator interface.
Programmable Detection Parameters
Selectable settings for sensitivity, energy discrimination, and fault levels may be entered by the administrator.
In the field, after site preparation, the CM267 can be installed and operating in less than an hour. When powered up, the system first acquires an initial background, typically within 20-seconds and is ready to run indefinitely. When the CM267 senses items on the conveyor the system starts comparing the current count to the most recent background data. Alarm comparisons are made every 200ms. If the count exceeds the alarm level, both audible and visual alarms will be triggered. The system monitors itself and indicates low and high background conditions.
Flexible Detection Options
The TSA CM267 is available in three configurations; Gamma, Neutron or a combination of Gamma and Neutron detection. Gamma provides detection of ionizing radiation and Neutron provides detection of Special Nuclear Materials (SNM) while the combined Gamma and Neutron provides the most powerful detection capabilities for radioactive isotopes even in shielded materials.
With the optional Remote Alarm Panel operators can view alarms up to 300m from the monitor. The TSA CM267 is compatible with TSA RAVEN™ communications software designed to both capture and view data and video images relating to a radiological detection incident.
