5V 30kpa Micro Differential Pressure Sensor For Air Compressor

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

Mainly technical parameters

Details:

• High precision
• High sensitivity measurement micro pressure
• Comprehensive accuracy up to 0.1% ~0.2%
• Output standard voltage current, RS485 signal
• Can be directly connected to PLC/ DSC/Computer
• Reverse polarity protection
• Imported wind pressure chip
• specially used in building high-rise laboratory rooms and pipelines

Wind pressure connection: Inner diameter 8mm air pipe (Heat the air pipe with hot water then connect inner diameter 6mm will more sealed)
Measuring pressure: The positive pressure range (example 0-1kpa) only needs to be connected to the longer end of the pagoda mouth, and the negative pressure is connected to the shorter end of the pagoda mouth.
Negative pressure range (example -5-0kpa) directly connected to the longer end of the pagoda mouth.
Measuring differential pressure: The long tube is connected to the high pressure end and the short tube is connected to the low.
