AP83 series explosion-proof pressure transmitter is a fully isolated intelligent field measuring instrument developed and designed by using fully isolated circuit technology and can carry HART communication protocol. Combined with advanced piezoresistive silicon chip sensor design and manufacturing technology, the sensor signal is converted Standardized signal output, the product has stable and reliable performance after long-term aging. It is applied to the open field with relatively harsh environment, and it is required to be able to observe the pressure display on site. It is suitable for process control and pressure measurement in petroleum, chemical, metallurgy, electric power, light industry, textile, environmental control and other industries.

EX-Explosion protection class according to Ex iaIICT6 according to ATEX can be used in the following hazardous environments: gas, vapour and mist: connection to zone 0, 1, 2, dust: connection to zone 20, 21, 22, mining area: M1 and M2 Class, this type of pressure transmitter by the intrinsic safety barrier or through the standard Zener diode input voltage 10…30V, output signal 4…20mA two-wire system.

The isolated explosion-proof Ex dⅡCT6 is provided with an explosion-proof hose 4 in charge of the outer teeth, and the electrical wiring protection must be considered when the sensor is installed.
