Lora wireless SF6 gas transmitter

Lora wireless SF6 gas transmitter

The SF6 monitoring host includes a CPU main control unit, an alarm unit, a communication unit, a display unit, and a ventilation control unit. By connecting with various detectors on site, the detection data transmitted by the detectors can be accurately received. Through calculation and analysis, it can determine whether it exceeds the standard. If it exceeds the standard, it will output actions such as sound and light alarm and start the fan. The host adopts a color touch screen to display real-time data measured on site. It can also work together with the keyboard to perform historical data query, system time setting, timed start fan setting and other operations. The operation interface is simple and friendly, and it also has the function of manually starting the fan. It adopts wall mounted installation method.

SF6+O2 gas transmitter ()

The detector includes a sulfur hexafluoride detection unit, an oxygen detection unit, a temperature detection unit, and a communication unit. The detection of sulfur hexafluoride uses ultrasonic detection technology to overcome the disadvantages of short service life and poor stability. It can monitor the changes in SF6 gas concentration and oxygen content in the environment in real time, and transmit the detected data to the SF6 monitoring host through RS-485 bus.
