RJ21 series Regional Radiation Monitoring System

Short Description:

The RJ21 series of regional radiation monitoring system is mainly for online real-time monitoring of X and rays in radioactive sites, and consists of a monitoring controller and multiple detectors. Use RS485 industrial control bus communication used, or wireless network communication connection. The dose rate for each detection point is shown in real-time.

technical feature

(1) The controller adopts high-speed embedded microprocessor, LED LCD display, humanized touch screen input, controller wall-mounted and desktop (optional) real-time sampling, and the data is quickly processed and refreshed every second

(2) Calendar clock and function abnormal, sound and light alarm mode can be set

(3) Can store over-threshold alarm and abnormal alarm records

(4) Communication mode:

-The standard RS485 interface solves the problems of unreliable communication, insufficient transmission distance and various communication cables

-Network communication mode can realize the wireless communication between controller and detector, controller and various devices, controller and upper computer, and the network is reliable and stable

-GPRS or Internet for global networking (optional)

(5) The alarm threshold of each detector can be set independently, and has upper and lower limit alarm functions

(6) Built-in fault detection, dose rate overload alarm and protection function, to ensure the normal operation of the instrument

(7) When the detector alarms, the host machine prompts the alarm probe number
