Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of capillary differential pressure transmitter in China. Welcome to buy high quality capillary differential pressure transmitter at competitive price from our factory. We also accept customized orders.
The HNP30-D is a high-performance intelligent single crystal silicon dual remote flat membrane/insert flange liquid level transmitter, adopting world-leading silicon pressure sensor technology and advanced packaging processes. Its core sensing unit is positioned at the top of the metal body, isolated from the medium contact surface to achieve excellent mechanical and thermal isolation, while glass-sintered leads ensure high-strength electrical insulation, minimizing temperature influence to an optimal ±0.04%/10K and delivering superior anti-interference performance.
Powered by a microprocessor with modular digital isolation design, it features a 24-bit ADC and innovative double compensation technology, boasting high accuracy grades of ±0.05%/±0.075%/±0.1% and long-term stability of ±0.1% over 3 years. Supporting HART protocol, it enables remote configuration and real-time digital temperature compensation, effectively reducing drift. The humanized external one-key zero function and shortcut menu allow easy parameter setting, meeting safety requirements for hazardous working conditions.
Suitable for gas, vapour and liquid media, it operates in a wide temperature range of -40℃~120℃ for media, with 2-wire 4-20mA output (HART optional) and auto-diagnostic fault alarm 3.9/21.0. It offers flexible range options (1KPa~4MPa), multiple dual remote flange configurations and customizable process connections, with high EMC compliance and explosion-proof options (ExdⅡCT6/ExiaⅡCT6). Ideal for diverse industrial level measurement scenarios, it provides reliable, precise and low-maintenance performance with strong environmental adaptability.
