MJS100 digital remote density relay is used to control and monitor the density of SF6 gas in sealed containers. It is applied to SF6 high-voltage circuit breakers, medium voltage switches, gas insulated equipment (GIS), high-voltage cables, transformers, and transformers, and is suitable for strong vibrations and harsh outdoor external conditions. It can display the SF6 gas density of SF6 electrical equipment from time to time, and has alarm and lock signal outputs. When SF6 gas leaks, it can timely output alarm and lock signals. This product is equipped with a communication interface, and can be connected wirelessly or wirelessly to transmit the SF6 gas temperature, pressure, density, and micro water and dew point data within the SF6 electrical equipment to the background. Through the self-developed cloud background, the data can be pushed to the designated user's mobile terminal, enabling designated users to monitor the operation of the SF6 electrical equipment from time to time without being on site, ensuring the safe operation of the SF6 electrical equipment.
