4-20mA micro differential air pressure sensor for
VentilatorHDP701 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 tubeMeasuring differential
pressure: high pressure to long tube, low pressure to short
tubeProduct Showcase Mainly technical
