Precision Sensing for Hydraulic Control Systems

 

Magnetostrictive Linear Position Sensors


In today’s demanding industrial environments, magnetostrictive linear position sensors are a cornerstone of hydraulic system accuracy and reliability. At Shenzhen Soway Tech Limited, we design advanced non-contact displacement sensors that provide absolute position feedback for cylinders and hydraulic actuators. Built on the magnetostrictive principle, our sensors offer high resolution, superior repeatability, and long service life, ensuring precise control even under the harshest hydraulic conditions.

 

How Magnetostrictive Linear Position Sensors Work

 

Our magnetostrictive sensors operate on a non-contact measurement principle, detecting the exact position of a movable magnetic marker along a waveguide rod. This allows for continuous absolute measurement without mechanical wear, ensuring stability and eliminating the need for recalibration. For hydraulic systems, this means dependable performance with minimal downtime and reduced maintenance costs.

 

Tailored for Hydraulic Cylinder Applications

 

Hydraulic systems in steel production, construction machinery, plastic injection molding, and mobile equipment require robust linear position feedback. Soway’s magnetostrictive linear sensors are designed for direct integration into hydraulic cylinders, providing precise stroke measurement for loads up to 35 MPa and beyond with special configurations. The sensors are sealed to IP67 or IP68 protection levels, making them resistant to hydraulic fluids, vibration, and high pressure.

 

High-Performance Features for Industrial Demands

 

Absolute position output ensures no loss of reference after power cycles

 

Resolution of 0.001 mm with repeatability within 0.01% F.S.

 

Fast update rates (1–2 ms) for real-time hydraulic system control

 

Multiple outputs (RS485, 0–10 V, 4–20 mA, SSI, Modbus) for flexible integration

 

Wide temperature tolerance from −40°C to +85°C

 

Shock resistance up to 500 g and vibration tolerance of 15 g

 

These specifications make Soway’s magnetostrictive displacement sensors the ideal solution for hydraulic cylinder monitoring, where both accuracy and durability are critical.
