Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of pfa magnetostrictive liquid level sensor in China. Welcome to buy high quality pfa magnetostrictive liquid level sensor at competitive price from our factory. We also accept customized orders.
The HNL30-B PFA magnetostrictive liquid level sensor is built for extreme industrial environments where corrosion resistance and measurement stability matter most. Constructed with high-purity PFA material throughout the wetted parts, it delivers outstanding protection against strong acids, alkalis, and various corrosive media that would damage standard level sensors.
By integrating mature magnetostrictive sensing technology with chemically inert PFA components, this instrument ensures stable and accurate level detection even in harsh chemical applications. The fully PFA structure, including the sensing rod, float, and electronic module enclosure, prevents corrosion, material degradation, and media contamination over long service life.
It supports a measuring range customizable from 0 up to 2500mm, with high precision: ±0.1mm resolution for lengths ≤400mm and 0.05% F.S. linearity for longer ranges. Equipped with 4-20mA analog and RS485 digital outputs, plus M12 connectors, it easily integrates with DCS, PLC, and on-site monitoring systems. Installation options include M50 thread, loose flange, and custom connections to match different tank setups.
This industrial-grade sensor carries an IP67 protection rating, operating reliably from -40℃ to +75℃. It withstands 50g shock and 15g vibration, complies with GB/T EMC standards, and includes reverse polarity and overvoltage protection. With low power consumption below 80mA and excellent sealing performance, it effectively eliminates leakage risks in corrosive and high-humidity environments.
The HNL30-B also supports optional functions such as multi-point temperature measurement and customized cable length to meet specific project requirements. It is widely applied in chemical manufacturing, acid base storage, electroplating, and other corrosive fluid monitoring scenarios, providing stable, maintenance-free operation for users who prioritize both corrosion resistance and high precision.

Measurement Principle |
The HNL30-B magnetostrictive level gauge is a high-precision continuous level measurement instrument based on the magnetostrictive effect. It calculates the liquid level height by detecting the propagation time of the magnetic coupling signal. It features high accuracy, high stability, and non-contact measurement, and is widely used in continuous level/interface monitoring in industrial processes. It supports the measurement of various media such as conductive/non-conductive, viscous/corrosive media. |
