Product Description


Adopting US imported 5651 chips

The selected patching process has zero point, full scale compensation and temperature compensation

High-precision and high-stability amplifying integrated circuits have the functions of moisture proof, anti-condensation, anti-leakage and lightning protection

the minimum pressure range can reach 1Pa, the maximum can achieve 100KPA! Part of the negative pressure can also be done! Various output signals are commonly used 4~20mA 0~10V 0~5V, etc.



The wind pressure and differential pressure transmitters are the standard form of our company's transmitters. It adopts imported high-precision, high-stability chip, which is assembled by aluminum alloy shell and stress isolation technology. It is processed by precision temperature compensation and circuit amplification technology and converted into 4-20m or 1-5V, 0-5V, 0-10V. Standard signal output, interface with industrial computer or distribution system, widely used in the measurement of air duct pressure or differential pressure of petroleum, chemical, metallurgy, power plant, etc., so as to realize the automatic measurement control of the production process.

The transmitter is compact and sturdy, light in weight and easy to install. The zero range can be continuously adjusted externally and has a wide migration range. It is suitable for measurement of various gas pressures or differential pressures with high measurement accuracy and good stability.
