Intelligent fluid equipment

The HNP30-B series intelligent pressure/differential pressure transmitter adopts the world's leading high-precision silicon pressure and differential pressure sensor technology and packaging process for the central sensing unit. The monocrystalline silicon pressure and differential pressure sensor is located at the top of the metal body, far from the medium contact surface, achieving mechanical and thermal isolation; The glass sintered sensor leads achieve high-strength electrical insulation with the metal substrate, improving the flexibility and transient voltage protection ability of electronic circuits. Platinum grade accuracy reaches ± 0.05%, and the maximum unidirectional overvoltage can reach 25MPa. Excellent static pressure performance, with an optimal static pressure error controlled within ±. 05%/10MPa, minimal temperature variation, and an optimal control of ± 0.04%/10K. In circuit design, a modular design with microprocessors as the core and advanced digital isolation technology is adopted, making the instrument highly anti-interference and stable. Using the Hart protocol for communication, remote operation can be carried out through Hart manual operators or computers with Hart software installed to complete measurement information configuration. At the same time, digital compensation technology is adopted, and the transmitter is compensated through built-in temperature sensors, improving measurement accuracy and reducing temperature drift. It has the characteristics of good long-term stability and high reliability. The most user-friendly external one click reset function meets the safety operation requirements in hazardous situations. The shortcut menu is convenient for operation and can complete all parameter settings, comprehensively improving the performance of the transmitter.
