SLT-08B Online Radiation Monitoring Alarm Device

Product Introduction:

SLT-08BThe series of regional radiation monitoring systems are mainly used for monitoring radioactive sites (irradiation equipment, industrial accelerators, medical accelerators, nuclear power plants, nuclear fuel production and reprocessing plants, etc.)X、γ、 Neutron radiation is monitored in real-time online, and when the dose exceeds a certain threshold, the sound and light alarm is used to alert the staff to evacuate in a timely manner. The system consists of a set of system software, a monitoring host, and multiple detectors. The host and detectors are connected through 485 bus protocol for communication.

Radiation monitoring host:

SLT-08BThe universal radiation monitoring host, as the basic unit in the radiation monitoring system, realizes functions such as data acquisition, information display, remote communication, and data storage. It can be used independently with different types of radiation detectors and control units, or integrated as a basic node in radiation monitoring systems.

The host can provide power for multiple digital radiation detectors and collect radiation information through a serial port, while remotely configuring the parameters of the digital radiation detectors; The on-site radiation information display adopts an industrial grade touch LCD screen, and the software display interface and configuration menu are simple and intuitive, fully simplifying user operation. It can simultaneously display on-site and view real-time detection data of multiple probes through remote computer software.

The host provides multiple digital communication interfaces, includingRS-485 serial port and Ethernet port, with the serial port using Modbus standard communication protocol and the Ethernet port using TCP/IP standard communication protocol. The connection with the detector unit and alarm control unit is achieved through a serial port.

Bus structure based on serial communication,SLT-08BCan be connected to a single digital radiation detector or multiple digital radiation detectors through a junction box; Additional multiple switch signal outputs can be provided, which can be connected to a single alarm control unit or multiple alarm control units through a junction box, and can be interlocked with the access control system for signal interlocking.

The most prominent feature of the detector is its functional expandability. The circuit and mechanical structure of the basic detector are reserved with dedicated interfaces, which can be connected with different expansion function modules without any structural or electrical modifications, realizing Ethernet port communication, on-site high-capacity data storage, wireless communication and other functions, making it convenient for users to combine according to their own needs.

Compliant with standards:GB 4793.1（IEC 61010-1）、GB/T 18268（IEC 61326）、GB/T 20438（IEC 61508）、GB/T 4835（IEC 60846）。
