Micro Differential Air Pressure Transmitter

Company Profile

Xi’an Yunyi Instrument Co., Ltd. is a national high-tech enterprise, specializing in the R&D, production and sales of pressure meter,level meter, flow , temperature instrument and automatic control equipment.The 2638-square-meter workshop has its own machining department and production line, focusing on R&D and production of customized and industrialized automatic instruments, providing complete set of customized solutions to create high-quality instruments.

Product Overview

The micro differential air pressure transmitter utilizes imported sensor chips with high precision and stability. By employing a unique stress isolation technology, precise temperature compensation, and high-stability amplification processing, it converts the pressure signal of the measured medium into a current, voltage, or 4~20mA standard signal output. High-quality sensors, sophisticated encapsulation technology, and assembly processes ensure the product's excellent quality and optimal performance.

Product Features

· Zero point and sensitivity compensation across the full temperature range.
· Strong anti-interference, excellent long-term stability, and diverse structures.
· Easy installation and use when matched with industrial computers, distributed control systems, and secondary display instruments.
