PROBE FOR DETERMINING AN ABSOLUTE POSITION OF A ROD OF A CYLINDER
摘要
<p>A probe for determining an absolute position of a rod relative to a cylinder with the rod having an associated pattern for indicating position includes a light source for emitting light. The probe further includes a light pipe for directing light emitted by the light source onto the pattern of the rod. A detector of the probe detects light and provides a signal indicative of the detected light. A lens produces an image of a portion of the pattern illuminated by the light on the detector and a controller is responsive to the signal from the detector for determining an absolute position of the rod relative to the cylinder.</p>
