There are many parameters vital in the HVAC system and among them, pressure and flow measurement are quite essential. Pressure sensors are crucial for monitoring air and fluid pressures, ensuring optimal performance and safety. Flow meters are vital for measuring airflow rates, water flow rates, and fluid velocities, enabling precise control of heating, cooling, and ventilation processes. Both sensors contribute to energy efficiency, and maintaining indoor comfort levels in HVAC applications.

Pressure can be described as the force applied to an area. There are many different systems of pressure measurement, with absolute pressure and sealed gauge pressure being two of the most common. There are many differences between these two measurements of pressure that have significant effects on their use and measurement.

In the IoT era, measuring pressure parameters for liquids and gases is becoming increasingly common in applications such as smart fire hydrants, smart water meters, smart homes, as well as the automotive and home appliance industries. Engineers often face challenges when selecting pressure sensor chips due to the variety of principles and product series available. They may not clearly understand the advantages and disadvantages, leading to decisions based on hearsay.

Huaxinlian Technology has introduced the industry's first fully automated laser temperature compensation process. This process includes online temperature coefficient testing and an active laser trimming system to adjust resistance, resulting in a complete range of ceramic pressure sensor cores with temperature coefficients below 0.02%/°C at the component level, filling a domestic gap.

HXL100 Oil and Gas Pipeline Leak Detection and Localization System— Dongguan HXL Science and Technology Co., ltd. has pioneered the development of a high-precision leak detection and localization system for oil and gas pipelines in China.

Ceramic is widely recognized for its high elasticity, corrosion resistance, wear resistance, and impact and vibration resistance. Ceramic pressure sensors, which use a ceramic diaphragm as the sensing material, are the most utilized type after MEMS pressure sensors in pressure measurement applications.

 It's underway! On May 20th, the long-awaited new facility of Huaxinlian was finally unveiled. The company took over 90 days from site selection, renovation, and equipment setup to testing and mass production.

On May 19th, Guangdong Xinhong Industrial Group and the Guangdong Electronic Information Engineering Research Institute of the University of Electronic Science and Technology visited our company for guidance.
