POSITAL measuring wheels turn rotary encoders into linear position sensors

February 26, 2016 By Miles Budimir Leave a Comment

POSITAL’s new series of measuring wheel accessories for its IXARC family of rotary encoders turns them into linear position sensors. When one of the wheels is mounted on the shaft of an encoder, the result is an accurate and reliable instrument for measuring linear motion and position. The new measuring wheels are available in circumferences […]

What are interferometric laser encoders and where are they used?

November 14, 2021 By Danielle Collins Leave a Comment

laser interferometer principle

Optical encoders such as glass scales are often used for linear position measurements that require micron-level resolution. But applications in industries such as semiconductor and aerospace — especially those that involve optics — require measuring capabilities in the nanometer and even picometer ranges, beyond the resolution of most scale-based optical encoders. For these applications, direct, non-contact […]

What type of encoder can measure speed?

August 23, 2021 By Danielle Collins Leave a Comment

encoder speed

Encoders and resolvers are used to track the angular or linear position of an object, such as a motor shaft (angular measurement) or a linear actuator (linear measurement). And with the addition of a clock signal, encoders and resolvers can also be used to measure the speed of the object. A resolver uses a rotor with […]

What’s the difference between radial and axial ring encoders?

August 12, 2021 By Danielle Collins Leave a Comment

radial and axial ring encoders

A traditional rotary encoder measures the position or speed of a rotating shaft, with mounting via a coupling or a hollow bore that allows the encoder to fit over the shaft. But not all rotating components have a shaft to which the encoder can mount. For example, direct-drive rotary motors — also known as torque motors, […]

What are inductive encoders and how do they differ from resolvers and LVDTs?

April 20, 2021 By Danielle Collins Leave a Comment

inductive encoders

Position measuring devices that rely on the principle of mutual induction include resolvers, linear variable differential transformers (LVDTs), and inductive encoders. Two of these technologies — resolvers and LVDTs — are based on the construction and operation of a transformer. In the case of an LVDT, voltage is applied to a primary winding and induced in […]
