JW-MDS(S09)magnetostrictive displacement sensor is a high-precision non-contact linear position sensor designed for absolute displacement and liquid level measurement in harsh industrial environments. With selectable measuring ranges from 50mm to 20000mm, multiple analog and digital output options, high repeatability, and IP65 to IP69 protection, it is ideal for hydraulic systems, industrial automation, tank level monitoring, metallurgy, and corrosive working conditions.
2. Product Overview
JW-MDS(S09)magnetostrictive displacement sensor is based on magnetostrictive measuring technology and delivers true absolute position output. Because it uses non-contact continuous measurement, it offers long service life, excellent reliability, and minimal maintenance. Even after power interruption and restart, the sensor does not need to be re-zeroed, making it especially suitable for industrial applications requiring stable and dependable feedback.High-precision displacement measurement can support structural deformation analysis, hydraulic equipment monitoring, and critical position tracking. For centralized multi-point monitoring, the sensor can be integrated into a complete structural health monitoring solution.
Compared with traditional displacement sensors, this product offers high accuracy, high repeatability, fast response, and strong anti-interference capability. It can also support multiple output signals, making integration with PLCs, industrial controllers, and automation systems easier.
