High-Precision Anti Interference Intelligent Pressure Transmitter

In the field of industrial automation measurement and control, pressure transmitters are core basic equipment that ensures accurate, stable and safe operation of production processes. Our self‑developed and manufactured industrial pressure transmitter series are developed for complex industrial working conditions. Integrating precision machining technology and intelligent digital compensation technology, they feature solid hardware quality and excellent measurement‑control performance. They fit multi‑industry industrial detection and control scenarios and deliver reliable pressure monitoring solutions for intelligent industrial production.

The industrial high‑precision pressure transmitter adopts an integrated full‑304‑stainless‑steel structure. Rugged and durable, it offers outstanding corrosion resistance, wear resistance, shock resistance and vibration resistance, reliably coping with harsh industrial environments featuring high humidity, dust and drastic temperature fluctuations. The core pressure‑sensing element is screened via fully‑automatic computer precision testing, paired with professional laser calibration technology to realize dual compensation for zero‑point and temperature performance over a wide temperature range. It fundamentally improves environmental adaptability and long‑term operational stability of the equipment. The pressure cavity is integrally machined from high‑grade 304 stainless steel and processed by full‑process laser seamless welding, delivering superior tightness and completely eliminating medium leakage risks to guarantee safety and reliability for long‑term continuous operation.

Equipped with self‑optimized intelligent digital circuits, the electrical system integrates automatic temperature compensation as well as radio‑frequency and electromagnetic interference suppression modules, solving common industrial‑site pain points including signal drift, data interference and numerical deviation. Comprehensive protection configurations include efficient lightning protection, surge protection and reverse‑polarity protection. Multi‑layer protection greatly mitigates impacts from industrial grid fluctuations and complex electromagnetic surroundings, extending service life and reducing downtime and maintenance costs. Supported by advanced digital temperature compensation technology, it calibrates data stably within ‑20 ℃ ~ +85 ℃ and minimizes measurement accuracy deviations caused by temperature changes.

Human‑oriented installation design features compact universal construction for diverse mounting scenarios. Quick assembly, disassembly and commissioning enable fast commissioning without complicated operations, suiting equipment matching and on‑site retrofitting requirements. It delivers outstanding performance parameters: gauge‑pressure measuring ranges cover full gradients from 0.1 bar to 600 bar, satisfying low‑, medium‑ and high‑pressure working conditions. It supports mainstream output signals such as 4‑20 mA and 0‑10 VDC, compatible with 2‑wire and 3‑wire wiring modes for most industrial control systems. Measurement accuracy reaches ±0.25 %FS, annual long‑term stability ≤ ±0.1 %FS, zero‑point and full‑scale temperature drift down to ±0.02 %FS/℃, ensuring high precision and consistent data.

For safety pressure bearing, the product provides 150 %FS normal overload and 200 %FS burst pressure, withstanding 100 g mechanical shock for prominent overload‑ and shock‑resistance and broad working‑condition adaptability. Operating temperature ranges from ‑40 ℃ to +85 ℃; storage temperature also spans ‑40 ℃ ~ +85 ℃ with excellent high‑/low‑temperature tolerance. Multiple standard pressure ports and electrical connections are available, including M20*1.5, G1/4, NPT1/4 and assorted connectors; customisation is supported for diverse equipment‑matching demands. The whole unit achieves IP65 protection grade for safe deployment in outdoor and industrial sites.

Boasting core strengths of high precision, high stability, strong anti‑interference and easy adaptability, this series of pressure transmitters is widely applied in industrial process measurement and control, hydraulic‑pneumatic control systems, industrial machinery manufacturing, automatic detection systems, pump stations and water‑treatment systems. It is the preferred core equipment for industrial automation measurement‑control, equipment matching and working‑condition monitoring.
