HDP 701 micro differential pressure air pressure transmitter is composed of OEM silicon piezoresistive differential pressure core.The shell is made of aluminium alloy. The two pressure interfaces are M8 threaded and cock structures,which can be directly installed in the measuring pipeline or connected through the booster pipe,and can accurately measure the pressure and differential pressure of the gas.It is widely used in the field of pressure process control in power and coal industry,such as boiler air supply and underground ventilation.The long tube is the high pressure input port and the short tube is the low pressure input port. Measuring Pressure:Only Long tube Measuring differential pressure:high pressure to long tube,low pressure to short tube
