Anti-corrosion ultra-high precision displacement (float level) sensor-LF701

Product introduction

Strong reliability: Because the magnetostrictive level meter adopts magnetostrictive principle, there is no mechanical movable part, so there is no friction, no wear and tear, the whole converter is closed in the tube, and the measuring medium is non-contact, the sensor works reliably, and has a long service life.
High precision: Because the magnetostrictive level meter works with waveguide pulse. During the work, the measured displacement is determined by measuring the time of the start pulse and the end pulse. Therefore, the measurement accuracy is high, and the resolution is better than 0.01% F.S. This is a precision that is difficult to achieve with other sensors.
Magnetostrictive level meter is easy to install and simple to maintain: Magnetostrictive level meter is generally installed through the existing pipe opening at the top of the tank, which is especially suitable for the installation of underground tanks and tanks that have been put into operation, and it can be installed without affecting the normal production during the installation process.
Convenient for system automation: magnetostrictive liquid level meter adopts standard output signal, which is convenient for microcomputer to process the signal, and easy to realise the networking work and improve the automation degree of the whole measuring system.
