| Number | Title | Issue Date |
| 8146417 | Hydraulic accumulator with position sensor A linear position sensor is installed inside the pressure vessel of a hydraulic accumulator to provide positional information for the moveable element inside of the accumulator. The positional information provides accumulator charge condition data for use in hydraul... | 04/03/2012 |
| 7716831 | Method of assembling an actuator with an internal sensor A method of installing a piston position sensor proximate to a closed end of a hydraulic cylinder is provided. The sensor is attached to the face of a piston and that piston/sensor combination is inserted into the cylinder tube to position the sensor in the desired ... | 05/18/2010 |
| 7609055 | Position sensing device and method A field-altering device for an inductive sensor has an elongated body with a substantially saw-tooth profile. The body is made of steel or other type ferrous material. With use in a Hall-effect sensor, the body moves relative to the sensor causing the field to vary ... | 10/27/2009 |
| 7300289 | Electrical cordset having connector with integral signal conditioning circuitry An electrical cordset for connecting a sensor connector used with a piston position sensor located within a high pressure environment and a control system. The cordset has a connector that is comprised of a housing having a cavity formed therein. A high pressure ass... | 11/27/2007 |
| 7290476 | Precision sensor for a hydraulic cylinder A sensor mountable within a hydraulic cylinder provides a precision signal indicative of the position of the piston. The sensor includes a flexible connector attached between the cylinder piston and a converting element for sensing the piston displacement. The conve... | 11/06/2007 |
| 7197974 | Position sensor A position sensor includes a stationary frame supporting a rotatable spool onto which a cable is wound in a plurality of individual windings. A distal end of the cable extends through a lead guide for attachment to an object whose position is desired to be sensed. A... | 04/03/2007 |
| 7100861 | Lead guide for cable extension type position sensors A position sensor and sensor assembly having a spool onto which is wound a plurality of individual windings to make up a cable coil. A free end of the cable extends through a guide for attachment to an object whose position is desired to be sensed. The cable passes ... | 09/05/2006 |
| 7093361 | Method of assembling an actuator with an internal sensor A method of installing a piston position sensor proximate to a closed end of a hydraulic cylinder is provided. The sensor is attached to the face of a piston and that piston/sensor combination is inserted into the cylinder tube to position the sensor in the desired ... | 08/22/2006 |
