Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of monocrystalline silicon sanitary type pressure transmitter in China. Welcome to buy high quality monocrystalline silicon sanitary type pressure transmitter at competitive price from our factory. We also accept customized orders.
The HNP40 series is a high-performance hygienic pressure and liquid level transmitter engineered for the pharmaceutical and food industries, fully compliant with EHEDG and FDA standards and optimized for CIP and SIP processes, withstanding high-temperature steam sterilization up to 150°C. Boasting an all-stainless steel structure with no hygienic dead ends, its media-contacting components use food-grade materials free of toxic substances, ensuring easy cleaning and sterilization.
Adopting advanced monocrystalline silicon pressure sensor technology with mechanical and thermal isolation design, the transmitter features a 24-bit ADC and microprocessor core with digital isolation technology, delivering an impressive inaccuracy of ±0.1% and minimal temperature influence (≤±0.05%URL/10°C). It supports Hart protocol communication for remote configuration and temperature compensation via a built-in sensor, ensuring superior anti-interference, stability and long-term reliability (±0.2%/3 years).
Offering flexible range adjustment, 4-20mA±Hart output with fault alarm, and multiple customizable options (diaphragm/process connection materials, mounting dimensions, display types), the HNP40 is compatible with standard process connections like DIN 32676 and ISO2852. With an IP65 protection class and wide operating temperature range (-20°C~85°C), it is ideal for measuring gases, vapours and liquids in hygienic industrial applications.
