Main Products
Description：
The smart fire‑protection pressure transmitter adopts the company’s self‑developed Flush diaphragm pressure sensor solution. Built‑in temperature‑compensation sensor enables full‑digital temperature compensation, linearity correction and zero‑point calibration. It delivers a burst pressure up to 5 times the rated pressure. Its structural components feature water‑hammer resistant design, which can replace traditional piezoresistive monolithic pressure sensor solutions and eliminate risks of diaphragm rupture and water leakage. In recent years, nearly 1 million units of this product have been shipped continuously.
Application‑fields: Smart Fire‑fighting
Description：
The smart industrial‑control pressure transmitter is fully independently developed by Dongguan Huaxinlian Technology Co., Ltd., a pressure sensor tailored for special‑purpose air compressor applications. To meet the requirements for ultra‑high overload capacity and high burst pressure in harsh environments such as mines and outdoor engineering (burst pressure up to 8 times the rated pressure), this product adopts a special ceramic sensor element, featuring ultra‑high‑pressure overload and excellent pressure‑shock resistance. It can replace imported oil‑filled silicon pressure sensor solutions.
Application‑fields: air compressors, water pumps and automation‑equipment
Description：
The smart agriculture pressure transmitter features a professional anti-interference circuit design, capable of withstanding water hammer impacts in pipelines. It offers high measurement accuracy, excellent corrosion resistance, and long-term sealing stability. Supporting dual-channel synchronous pressure data acquisition, it enables real-time monitoring at two points simultaneously. The device operates reliably across a wide range of temperature variations and is resistant to complex mixed-water environments containing fertilizers, pesticides, detergents, and other chemicals. It is well-suited for various smart agriculture applications, including farmland irrigation and integrated water‑fertilizer management systems.
