High voltage or medium voltage circuit breakers commonly used for distribution and transmission are reliable if they are able to operate in steady and controlled conditions.
The use of SF6 or Dry-Air as quenching gas is extremely important to guarantee a safe operation during the life of equipment.
In order to have continuous check of gas filling and immediate warning in case of leakage the EMD transmitter is suitable to be connected to most standard monitoring systems.
It is ready to operate immediately after installation because of our technology based on ceramic primary element capable of reading the temperature and pressure of gas and calculate density.
All the materials used, such as thick ceramic and stainless steel are insensitive to chemical attach of corrosive and polluted gases.
The case is very robust and it is tested to face heavy duty conditions, so all the inner parts are immersed into resin to guarantee resistance to moisture and vibrations.
The sensor is available with both analog or digital output.
The analog version is a two wires loop powered and the digital is a standard Modbus RTU 485.
Density calculation is based on measurement of two physical data: pressure and temperature; proprietary algorithm is used to convert these data into density and can be customized by changing some coefficients to meet specific request.
