摘要：An arrangement is provided for determining the relative angular orientationbetween an excavator bucket and the dipper stick of an excavator. The excavator bucketis mounted on a bucket linkage that is pivotally secured to the end of the dipper stick. Anhydraulic actuator has an hydraulic cylinder pivotally connected to the dipper stick, and apiston pivotally connected to the bucket linkage. Extension or contraction of thehydraulic actuator causes the excavator bucket to be pivoted by the bucket linkage withrespect to the dipper stick. A cable extension linear position transducer having a

transducer casing, a sheath extending from the casing, and an extensible cable extendingfrom the sheath, provides an electrical output related to the extension of the cable fromthe sheath. A transducer mounting secures the casing of the cable extension linearposition transducer in fixed relationship to the hydraulic cylinder. A clip secures theextensible cable to the piston. By this arrangement, extension or contraction of thehydraulic actuator causes the output of the transducer to vary, thus providing anelectrical output related to the relative angular orientation of the excavator bucket withrespect to the dipper stick.
