Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of intelligent pressure transmitter in China. Welcome to buy high quality intelligent pressure transmitter at competitive price from our factory. We also accept customized orders.
The HNP20-C Digital Pressure Sensor is a high-performance electronic pressure measuring device engineered for diverse industrial scenarios, including hydraulics, pneumatic control, motorised brake systems, boiler operation and constant pressure water supply. It adopts high-precision imported pressure-sensitive components and advanced digital circuits, which convert pressure signals into precise current and switch signals, boasting the core advantages of high accuracy, fast response, stable performance and a compact structure. The sensor features easy operation and flexible installation, with a rotatable design and thread mounting for effortless deployment in various working environments.

It supports measuring various liquids, gases and vapours compatible with 304/316/316L stainless steel, with an ultra-wide measuring range from 0-0.6MPa to 0-1000MPa and overload pressure resistance of 2 times the full scale. Offering Class 0.25, 0.5 and 1.0 accuracy grades, it has a rise time ≤5ms (up to 90%FS), temperature compensation within 0~70℃ (zero drift ≤0.05%FS/℃) and long-term stability of 0.5%FS/year. The sensor provides two output types: single-point (4-20mA analog + two-way switch) and double-point (two-way switch), with switch life ≥100,000 times and reliable switching performance.

Constructed with 304/316 stainless steel for both housing and media contact parts, it has an IP65 protection rating, enduring -20~+85℃ ambient and media temperatures. Standard configurations include M20×1.5 pressure thread and M12 electrical connector, with customizable process/electrical connections available. Equipped with a user-friendly panel with menu display and button adjustment, it enables convenient parameter setting and output switching, and is an ideal reliable pressure measurement solution for industrial process testing and control.
