TSM Linear Position Sensor

Linear position sensors are used to measure linear displacements. TSM Sensors' range of magnetostrictive sensors consists of a series of non-contact linear position transducers.

What are magnetostrictive sensors?

Magnetostrictives are always linear sensors that measure the position of a cylinder through a magnetic cursor placed on a rod at a maximum distance of three meters. They are made of stainless steel and can be mounted either outside the cylinder or inside it. The technology used ensures high accuracy, with a maximum error of a few tenths of a millimeter for precise measurement over the entire operating range. In addition, since there is no mechanical contact, the life cycle is virtually infinite.

These sensors are known for their durability and can measure distances up to several meters, as their accuracy is directly proportional to the length of the embedded waveguide. They are also little affected by vibration, shock, and temperatures below 100°C. However, changes in temperature can affect their accuracy, and their purchase cost is relatively high.

TSM's line of linear position transducers

Linear position transducers are designed primarily for mobile machinery (agricultural vehicles, construction and earthmoving and handling and hoisting) and are available with either a flange or threaded connection. Both types can be installed inside oledynamic cylinders.

The special design and wide range of slider configurations simplify installation and ensure full compatibility with cylinder manufacturers' specifications.

A temperature range of -40 to +85°C, operating pressures up to 350 bar, as well as high vibration and shock resistance give the sensor considerable robustness, a key feature in heavy-duty applications.

High performance in terms of measurement transduction, such as linearity, hysteresis and repeatability.
