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 transmitter adopts piezoresistive pressure sensor chip, and uses the film resistance on the substrate to carry out zero point correction, zero point temperature compensation and sensitivity compensation. The high-performance and stable silicon chip package makes it high static pressure resistance, anti-interference, stable and reliable. Therefore, the product can be applied to the micro differential pressure field combination of various gas measurement. It is an ideal micro differential pressure measuring instrument in the field of industrial automation.
