SF6/O2 dual gas detector for detecting sulfur hexafluoride leakage alarm

SF6/O2 dual gas detector for detecting sulfur hexafluoride leakage alarm

substationThe sulfur hexafluoride alarm in the distribution room is a device specifically designed to detect sulfur hexafluoride gas leaks and display gas concentration in real-time,24-hour real-time online detection alarm device. sulfur hexafluoridegasThe alarm consists of two parts: a gas alarm controller and a gas detector. The gas detector is installed at the gas leak detection site and can achieve real-time detection of gas concentration through the core component gas sensor. It can also work independently. The gas alarm controller can be placed in the duty room, receiving the concentration detected by the gas detector, and realizing the display of concentration and the sound and light alarm function after the concentration exceeds the standard. It can also be linked to external equipment (such as solenoid valves, exhaust fans, sprinkler devices) and uploaded through switch valuesPLC、DCS、 Fire protection system, etc.

1. Sulfur hexafluoride alarmCan be simultaneously appliedMonitoring of SF6 gas concentration and O2 content;

2. Sulfur hexafluoride alarmhaveSelf setting function for O2 and SF6 concentration alarm points:

3. Sulfur hexafluoride alarmIt has manual forced exhaust and timed exhaust functions, where the timed exhaust time can be set according to actual working conditions. And the last exhaust stop time can be queried;

4. Sulfur hexafluoride alarmhaveSF6 gas concentration over limit alarm, voice prompt, automatic ventilation.

5. Sulfur hexafluoride alarmIt has real-time hypoxia alarm function.

6. Sulfur hexafluoride alarmEach detection unit can work independently and detect simultaneouslySF6 and O2 leakage,.

7. Sulfur hexafluoride alarmIt can automatically start timed ventilation during time periods, automatic ventilation for leakage exceeding standards, manual ventilation, and last exhaust time reminder functions.

SF6/O2 dual gas detector for detecting sulfur hexafluoride leakage alarmProduct Features:

1. Using imported components, stable performance and low power consumption.

2. High precision and fast response speed.

3. Three wire 4-20mA standard signal output; M-BUS standard signal output.

4. The setting and modification of its own parameters can be achieved through the instructions of the controller.
