Celesco Cable-Extension Position Transducers Model PT9150
With its incremental optical encoder and industrial design this rugged transducer provides the highest accuracy and longest life of any measurement device of its kind. This model is available in a wide variety of resolutions and out- put stages to fit virtually any requirement.
It can measure up to 550”, yet when its cable is retracted it is only 6” long. Its small size and low-cost-to-measurement ratio offers remarkable flexibility and value.
