Cheap Air Differential Pressure Transmitter Stack Flow Water
Pressure Sensor
Description 4-20ma air differential pressure transmitter stack flow
This series of micro differential pressure transmitters
incorporates a piezoresistive pressure sensor chip, utilizing film
resistance on the substrate to perform zero-point correction,
zero-point temperature compensation, and sensitivity compensation.
The high-performance and stable silicon chip package ensures high
resistance to static pressure, anti-interference properties,
stability, and reliability. As a result, the product is suitable
for various gas measurements in the micro differential pressure
field, making it an ideal instrument for precise micro differential
pressure measurements in industrial automation applications.
