why choose our magnetostrictive position sensor
By offering high accuracy, durability, multi-position measurement capabilities, and simple installation in a compact and low-maintenance package, magnetostrictive displacement sensors provide a robust and reliable solution for position measurement in various industrial applications.
Non-Contact Operation
The magnetostrictive position sensor measure position without any physical contact between the sensing element and the object being measured, eliminating wear and tear. This allows for long service life and high reliability
High Accuracy and Resolution
Magnetostrictive sensors provide high resolution (ability to detect small position changes) and low non-linearity (deviation from a straight line), with non-linearity coefficients as low as 0.02%. This makes them suitable for applications requiring precise position measurement
Long Measurement Range
They are available in stroke lengths ranging from 25mm to 10m, enabling accurate position measurement over short as well as very long distances
Absolute Positioning
Magnetostrictive sensors provide absolute position feedback, eliminating the need for re-homing after power interruptions, unlike incremental encoders.
Fast Response Time
The sonic wave used for position detection travels at around 3000 m/s (about 10 times the speed of sound), allowing for fast response times.
Durability in Harsh Environments
These sensors are inherently rugged and can withstand harsh operating conditions such as extreme temperatures, vibrations, shocks, and corrosive environments found in industries like mining, construction, and steel making.
Simple Installation
Magnetostrictive sensors can measure position through non-magnetic barriers like plastic, ceramic, or aluminum, simplifying installation by not requiring a direct line of sight between the sensor and the object being measured
Absolute and Incremental Outputs
Magnetostrictive sensors are available with various output signal types, including analog (voltage or current), digital (start-stop pulses), and serial communication protocols like SSI

how to install it ?
The pressure measuring rod of RH series products can be easily separated from the entire electronic compartment of the sensor (two M4X65 screws), which can be quickly replaced without pressure relief, and the pressure measuring rod can become a permanent part of the oil cylinder.

Q5: What type of signals does a magnetostrictive displacement transducer produce?
There are types of output signals: SSI and analogue. All devices of this category are absolute sensors. They determine an absolute position of magnet.
Q6 :What are the characteristics of magnetostrictive materials?
Magnetostriction, known as the ability of magnetic materials to expand or contract in response to magnetic field, is a key property of Fe-Ga alloys exploited in various types of transducers. Usually, thin films of Fe-Ga deposited on rigid substrates suffer from a clamping effect that hinders the propagation of strain.
