| 20140076065 | Coordinated Ratiometric Compensation for High-Precision Load-Cells - Apparatus and associated methods relate to a load-cell measurement system having an output that is substantially independent of the system voltage source, by providing compensation for the source voltage variation using both a compensating offset voltage and a compensating reference voltage, these compensating voltages having a predetermined relationship with each other. In an illustrative example, the supply voltage may be directly connected to a load-cell, an instrumentation amplifier, and a compensation circuit. In some examples, the compensation circuit may include a chain of impedances which may generate two mutually related voltages both being scaled to the supply voltage. The first scaled voltage may, for example, substantially compensate offset of the load-cell measurement system. The second scaled voltage may, for example, substantially compensate for gain. In various examples, the compensating offset voltage and gain voltage may have a predetermined relationship so as to provide coordinated compensation of the system. | 03-20-2014 |

| 20220136915 | DUAL PRESSURE SENSOR - A controller configured for monitoring disturbances of a pressure sensor assembly includes at least two sensors. The at least two sensors are configured for measuring a pressure and wherein the at least two sensors have a sensor dependent measurement sensitivity for the pressure, and at least one of the sensors is sensitive for a disturbance with a sensor dependent disturbance sensitivity. A ratio of the measurement sensitivity and the disturbance sensitivity is different for the at least two sensors. The controller is configured for detecting the disturbance by comparing outputs of the at least two sensors. | 05-05-2022 |

| 20100251833 | DEVICE AND METHOD FOR TEMPERATURE COMPENSATION TESTING OF DIGITAL LOAD CELLS - A device and method for effectuating the temperature compensation testing of digital load cells. The device uses conductive heat transfer to establish and maintain the temperature of the load cell(s) during testing. The device may include a vessel into which one or more load cells to be tested are placed. Temperature control of the load cells may be accomplished by circulating a temperature controlled fluid through the vessel. The vessel containing the one or more load cells may then be placed in a load application device that applies a load(s) to the one or more load cells during testing. Readings from the one or more load cells are used to establish a temperature compensation factor for each load cell tested. In other embodiments, temperature control of the load cells may be accomplished by placing the load cells in contact with a solid heat transfer element(s). | 10-07-2010 |
| 20110023630 | CIRCUIT COMPENSATION IN STRAIN GAGE BASED TRANSDUCERS - A methodology for selecting and properly placing foil strain gages on a transducer in a Wheatstone bridge, which provides a more consistent creep response, especially when the transducer temperature is changed. A transducer includes a counterforce subjected to a predetermined physical load that provides tension and compression strains (positive and negative, respectively). The transducer also includes a plurality of strain gage grids that are operatively attached to the counterforce in the tension and compression strain areas of the counterforce and generate electrical signals. The plurality of strain gages are electrically connected in a Wheatstone bridge circuit where their electrical signals due to creep are cancelled. | 02-03-2011 |
| 20150075296 | Load Cell for Measuring Load on a Rod - A load cell for measuring load in a rod, the load cell is described. The load cell is formed by a cylindrical strain member having a cylindrical aperture there through. The cylindrical aperture sized to fit the rod. The strain member includes a plurality of slots that create contact points there between for strain member to contact the rod in a predicable manner. A plurality of strain gages located adjacent to the contact points, the strain gages producing an electrical voltage proportional to the load on the rod. | 03-19-2015 |
