Product Introduction
The magnetostrictive liquid level sensor is a new type of liquid level sensor developed based on the Weidman effect of magnetostrictive materials. It can provide high-speed, reliable, accurate, and continuous liquid level signals in harsh working environments.
The magnetostrictive displacement sensing technology was first successfully developed in the United States in 1975 and is mainly applied in important core fields such as aerospace and national defense. Due to its involvement in national strategic interests, this technology has always imposed a blockade on China. In recent years, with the support of national and provincial science and technology departments, our unit has finally overcome all technical difficulties of this sensing technology through dedicated research, achieved industrialization, and has fully independent intellectual property rights to this product.
Functional characteristics
※ Multiple interface output methods, including RS485 and analog 4-20mA output.
※ High precision real-time water level measurement, ultra-low blind spots, widely used.
※ RS485 Modbus RTU protocol, can be customized with other protocols for easy access to various software platforms.
※ Unique water surface fluctuation processing algorithm, stable data, unaffected by water surface fluctuations.
※ IP68 protection level, suitable for various outdoor environments, with a long service life.
※ Easy to disassemble and install installation method.
※ Non contact measurement with high stability.
※ Absolute displacement measurement is not affected by movie noise.
※ Strong adaptability to temperature environment.
※ It can replace liquid level sensors such as LVDT, electronic water level gauge, float encoder, etc.
