DA-800A Regional Radiation Detection Online Alarm Instrument

Regional Radiation Detection Online Alarm Instrument

Product introduction           

DA-800A online neutron and X/γ radiation alarm instrument is an online continuous measurement and alarm device for neutron and X/γ radiation. It uses a high-speed embedded microprocessor and a 7-inch IPS touch LCD display. It can monitor in real time and respond quickly; it also ensures the simplicity and humanization of operation. A reliable communication method is adopted between the host and the probe, which ensures that the host can display the specific dose rate of each probe in real time, and can indicate the current status of the probe (normal/offline/overload) in real time. In addition, radiation area monitoring software can be selected according to site requirements.

Features

• The high-speed embedded microprocessor is selected to ensure the real-time performance of monitoring data and status.

• It adopts a 7-inch 1024×600 IPS LCD display and a full Chinese operation interface, which is easy to use and easy to operate.

• Dose rate unit switchable (μGy/h, μSy/h).

• One host can mount multiple probes at the same time, the default is four probes (expandable to more than 30).

• With the function of automatically identifying the probe, it is convenient for the staff to replace the probe.

• The alarm threshold is continuously adjustable (factory default high threshold is 25uGy/h, low threshold is 0.0Gy/h).

• The status of each probe can be displayed in real time: normal/alarm/overload/offline.

• The probe has multiple alarm modes, sound and light alarm (standard configuration); it can also be extended to an external alarm, relay switch alarm.

• Each probe has two alarm modes (upper limit alarm/lower limit alarm), which are flexibly applicable to various radiation safety alarm places.

• The host can automatically record the threshold alarm and store it automatically, and it will not be lost after power failure; the threshold alarm record can be queried manually.

• It has a real-time clock function, which can display the year, month and day in real time, and the operation of the clock will not be affected by power failure.

• Communication method: standard RS485 interface, transmission distance up to 800 meters.

• An optional built-in battery is used for on-board dose monitoring and occasions where the working power supply is unstable.

• Optional nuclear radiation online monitoring system management software, which can summarize the dose information of each location, display it in real time, make data graphs, review history, etc.

• Can be customized and developed according to requirements....

Application range

• Radioactive waste repository, industrial non-destructive testing

• Isotope application plant area, gamma irradiation

• X-ray diagnostics in hospitals, cobalt therapy, nuclear power plants....
