Low Pressure (differential) Transmitter
Introduction
This type is 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.

Outline Construction
(Unit: mm)
High precision
High sensitivity measurement micro pressure
Comprehensive accuracy up to 0.1%~0.2%
IP65 housing protection
Pagoda M10 installation
Imported wind pressure chip - Specially used in building high-rise
laboratory rooms and pipelines
Wide range of applications - Canbe directly connected to
PLC/DSC/computer
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.
