Specifications
| Detector | Dual Ion chamber. LND501 and LND50343 to cover range 0.1mR/Hr to 100R/Hr.
Compared with GM tubes, which have 5×10^10 counts limit, the Ion chambers have a much longer life and higher reliability. |
| Detector circuit | The radiation dose test detector signal will transmit to measurement unit via balanced-line transmission. |
| Check source | Check source with motor drive mechanism.
10uCi Cs137 is built into each detector box. A motor moves the check source close to the detector to check the response/calibration of detector. |
| Measuring Module | NIM double width module, built using a real-time micro-controller. |
| Alarm Module | NIM signal width module will provide all the relay and local audible & visible alarm. |
| Remote module | NEMA type 4 box module with alarm indication, audible alarm, exit sign. It communicates with measuring unit via RS485. |
| Central computer with Data trending, data logging. | Designed in VB.net. |
| Qualification | Radiation Dose for detector module
Temp/Humidity: 50oC/95%RH EMC/EMI Software qualification: Category III software |
