Optical Position Transducer with Redundant System Architecture Position Measuring in Hydraulic Cylinders

摘要

There are various technical solutions to measure the current length of hydraulic cylinders. The sensor to measure the cylinder length presented here is based on optical recognition of a binary barcode situated on the piston rod, which has a unique code structure in every position. The sensor is available as a redundant version in order to meet more stringent safety requirements. Its compact design makes the sensor particularly suitable for mobile applications in agricultural and construction machinery.
