Linear Sensor

Repeatable Length Measurement

POSITAL’s LINARIX draw wire sensors measure linear motion by displacing a stainless steel wire a_icon wound around a wire drum b_icon that actuates the rotary encoder c_icon coupled to it via coupling d_icon . A spring e_icon is used to retract the wire in the housing. The encoder provides a proportional output. Measurements are highly accurate, reliable and the systems have very long lifetime.

The LINARIX line offers a wide range of measurement lengths ranging from 1 m to 30 m [3 to 98 ft] and position output in almost every available industrial interface both analog and digital as well as incremental and absolute. The line is featured with different mechanical options, housing materials and springs to enable you to always find the most suitable product for your application.

Principle of a linear sensor

Compared to conventional linear pots and linear measurement systems using multiple gears and encoders LINARIX line are more durable and can be used to replace them directly avoiding common problems of slippage and wear. Draw wire sensors from POSITAL provide extremely precise measurements because of inherent accuracy of encoders while rugged construction ensures reliable performance even under extreme conditions.
