The differential air pressure  sensor transmitter is developed on the basis of industrial class advanced ICs technology.It can be used for the measurement for air pressure and air differential pressure . It can be used for air and other dry nonflammable gas without corrosive. By the built-in electronic wiring, the physical value can be transmitted to analog voltage and current output or digital serial port output with Modbus protocol. The differential pressure sensor is not used for pressure measurement of liquids.

The air differential pressure transmitter can provide high accuracy with low price. It is our standard type pressure transmitter.With metal enclosure and advanced air differential pressure sensor, the air differential pressure transducer can ensure high performance with good cost-effective solution. The differential pressure transmitters have been widely used for HVAC,building automation,electric power, environmental protection, dust removal,light spinning, leak detection, etc.
