Product functions
Overall dimensions

SF6 gas is widely used in power equipment as insulating medium and arc extinguishing gas, especially in high-voltage circuit breakers, transformers, transformers, capacitors, lightning arresters, fuses, etc. In case of leakage, equipment pressure and insulation capacity will be reduced; Polluting and destroying the atmospheric environment and increasing the greenhouse effect; Accumulation in the lower space leads to accidents such as hypoxia of the brain of the staff, even rapid asphyxia; Under the influence of partial discharge, high temperature and other factors, SF6 gas will produce highly toxic decomposition products such as SF4, SF2, SOF2, etc. This product is a sensor using NDIR infrared absorption detection principle. The concentration is determined according to the absorption amount of SF6 gas at 10.5um.

It can be widely used for SF6 gas leakage detection in power industry and SF6 gas concentration analysis in other occasions. The optional output signal can meet the requirements of different measurement environments and various high-precision and high stability measurements.

This product uses 470MHz Lora wireless communication technology platform, and the communication protocol uses the Internet of Things micro power wireless network communication protocol of the State Grid transmission and transformation equipment to achieve dual-way communication, and has RS485 communication mode to meet users' multiple communication needs.
