The core advantage of this magnetostrictive displacement sensor is its exceptional resistance to electromagnetic interference (EMI), ensuring stable data output even in environments with high-voltage equipment, welding machines, or power inverters. Unlike inductive or capacitive sensors, it uses a non-contact magnetic coupling principle, so there is no wear between components, resulting in a service life of over 100 million cycles, which is far longer than contact-type sensors. With a measurement accuracy of ±0.05mm and resolution of 0.005mm, it balances precision and durability for heavy-duty industrial applications. Equipped with CANopen and 4-20mA output signals, it supports seamless integration with industrial fieldbus systems, enabling remote monitoring and control. The 316L stainless steel housing and IP68 protection rating allow it to be submerged in oil or water up to 10 meters, and it operates reliably in temperatures ranging from -40℃ to +85℃, resistant to corrosive gases and liquids in oil refineries and metallurgical plants.
This magnetostrictive displacement sensor has a measurement range of 0-2000mm, suitable for medium-to-large range position detection in harsh environments. Its measurement accuracy is ±0.05mm, with a resolution of 0.005mm, ensuring precise and repeatable data. It supports two output signals: CANopen for high-speed digital communication in industrial fieldbus systems, and 4-20mA analog signal for compatibility with traditional control systems. It operates on a stable 24VDC supply voltage, which is standard for industrial automation equipment. The response time is 0.8ms, enabling real-time monitoring of dynamic movements such as hydraulic cylinder strokes. Housed in a 316L stainless steel tube with a polished finish, it provides superior corrosion resistance to acids, alkalis, and salt spray. The protection grade is IP68, allowing continuous submersion in water or oil up to 10 meters. The working temperature range is -40℃ to +85℃, and the sensor’s outer diameter is 25mm, with a net weight of 520g. Mounting options include built-in installation for hydraulic cylinders and external bracket mounting for fixed equipment.
This EMI-resistant magnetostrictive displacement sensor is ideal for industries operating in harsh, high-interference environments. In the oil and gas sector, it is installed in downhole tools, pipeline valves, and offshore drilling platforms to monitor valve position, pump stroke, and drill pipe depth, withstanding corrosive oil and seawater. In metallurgical plants, it measures the position of furnace doors, rolling mill rolls, and steel ladle tilting mechanisms, resisting high temperatures and strong electromagnetic interference from smelting equipment. In mining machinery, it is used on hydraulic shovels, conveyor belt adjusters, and mine hoists, withstanding dust, vibration, and extreme temperatures. Additionally, it is applied in renewable energy systems such as wind turbine pitch control and hydroelectric dam gate position monitoring, providing reliable data to ensure safe and efficient operation. Its robust design makes it a preferred choice for critical industrial processes where reliability is non-negotiable.
