The Environmental Management System Certification Certificates (Certification Standard: ISO 14001:2015) of Dongguan HXL Science and Technology Co., ltd. (Parent Company) and Wan'an HXL Science and Technology Co., ltd. (Subsidiary ) were approved for renewal on August 13, 2024, and have taken effect immediately.

Recently, Wan'an HXL Science and Technology Co., ltd.—the wholly-owned subsidiary of our company—was officially awarded the qualification plaque for the "Dongguan Sci-Tech Innovation (Talent) Outpost" and became a core participating enterprise in the first municipal-level sci-tech innovation outpost in Ji'an City.

Wan'an HXL Science and Technology Co., ltd.—the production base of Huaxinlian Technology—has completed the renewal of certification for the IATF 16949:2016 Quality Management System Standard on July 10, 2024. The certification scope continues to cover the "design and manufacture of pressure sensors".

Pressure sensor is a device that can sense pressure. It plays an important role in civilian and industrial use. Knowing about it helps people understand its importance, and this article serves as a guide, you will know the definitions of pressure sensor, the working principle, pressure types and its applications.

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.
