Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of digital display pressure switch in China. Welcome to buy high quality digital display pressure switch at competitive price from our factory. We also accept customized orders.
The HNP10-C Digital Pressure Switch from Honno is a high-precision industrial pressure monitoring device featuring advanced diffused silicon sensor technology for accurate pressure measurement, with signals processed by a dedicated circuit and converted into standard industrial electrical signals for real-time output and display. Boasting a one-piece injection-molded engineering plastic housing, it combines durability with easy installation, requires no frequent calibration, and delivers an ultra-fast response time of less than 10ms, making it suitable for a wide range of industrial applications.
Equipped with a high-brightness LED digital display and intuitive button adjustment for switch settings, it offers exceptional performance: a switch accuracy and overall accuracy of ≤±0.5% of range, annual drift stability of ≤±0.3% of range, and factory-set configurable switch point hysteresis of 0.5% of the switch setting. Powered by 12-30Vdc with a max no-load current of 30mA, it features configurable PNP/NPN output, selectable normally open/closed modes and 100Hz frequency output, with a switch load of <200mA and comprehensive wiring protection against phase inversion, overload and short circuits.
Constructed with 316L stainless steel sensing diaphragm, 304 stainless steel process connection and nitrile/fluororubber sealing, it has an IP67 protection class and M12x1 connector wire outlet. It supports gauge/negative pressure measurement with a broad pressure range up to 1000bar, multiple process thread options and diverse output signals (switching/frequency, 4-20mA, 1-5V, RS485), adapting to ambient/medium temperatures of -20~80°C/-20~85°C and storage temperature of -30~80°C, serving as a flexible and reliable pressure control solution for industrial scenarios.
