Used for monitoring sealed containersSF₆The micro water content, density, pressure, temperature and other data of the gas have real-time remote monitoring function. Adopting intelligent compensation technology, real-time tracking is possibleSF₆The non-linearity of gas pressure changes and the variation of micro water content are accurately measured and widely used. Suitable for monitoring high-voltage systems. We can provide various solutions such as supporting new substations and intelligent transformation of existing substations.

1. Integrated design effectively ensures airtightness.

2. Only connect to the main body through one ventilation port to reduce the risk of air leakage.

3. The combination of remote density transmitter and dew point sensor enables on-site collection and processing, while reporting density, pressure, temperature, and micro water content information.

4. Digital signal output,Working with backend serverspass throughRS485Facilitate communication for on-site networking and debugging.
