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.
· Widely used in chemical, petroleum, metallurgical industries,
power plant air ducts, coal mine ventilation pressure, boiler air
supply pressure or flow testing, and pressure process control
fields.
