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
