摘要： A force, weight or position sensor unit and sensor element incorporated into an apparatus for microindentation hardness testing and surface imaging which allows immediate imaging of the surface subsequent to hardness testing. The sensor uses a multi-capacitor system having drive and pick-up plates mounted on an appropriate suspension system to provide the desired relative motion when a force is applied to the pick-up plate. The output signal is run through a buffer amplifier and synchronously demodulated to produce a signal proportional to force or displacement. The sensor element is mounted on a scanning tunneling microscope base and a sample mounted on the sensor. The force sensor is used for both measuring the applied force during microindentation or micro hardness testing and for imaging before and after the testing to achieve an atomic force microscope type image of the surface topography before and after indentation testing.

摘要： A device for sensing food weight in a microwave oven includes a bracket formed into one body and mounted with a motor assembly having a motor axis, a movable electrode plate fixed to an extending piece separated from the bottom of the bracket and a printed circuit board in which a fixed electrode plate is printed. The printed circuit board is inserted in a space formed between the bottom of the bracket and the movable electrode plate. An initial food weight is set by varying an overlapping area of the movable electrode plate and the fixed electrode plate. The food weight is sensed by using the distance variation between the movable electrode plate and the fixed electrode plate. Since no weight is applied to the printed circuit board, the deformation and the destruction of the printed circuit board is prevented. Further, the distance between the fixed electrode plate and the movable electrode plate may be maintained constantly.

摘要： A device for checking the weights of individual capsules in a stream of capsules by passing the stream of capsules past a capacitance sensor which measures the capacitance of each capsule as representative of the capsule weight, and passing the stream of capsules past a velocity sensor which measures the velocity of each capsule as representative of the capsule weight. The measured capacitance and measured velocity values are each compared against preset ranges of values, and a capsule is mechanically deflected from the moving stream if the comparison shows either measured value to be outside the respective preset range of values.

摘要： A load sensor which has an elongate hollow body 11, preferably formed as a metal extrusion, and which forms a first capacitative plate 21. A second parallel capacitative plate 15 is formed on an insulating body which is held in place relative to the extrusion by a resilient support 16. Application of a load to the extrusion causes variation in the gap between the plates of the capacitor, thus affecting the capacitance in a manner which is measured and processed to provide an output signal which is directly proportional to the applied load.

摘要： This invention relates to force responsive transducers and more particularly concerns a micromachined, solid state micro-scale. The device consists of a central silicon platorm surrounded and supported by a thin silicon membrane. The silicon substrate is placed over an aluminum pad recessed into a well on a supporting glass substrate. The micro-scale responds to a static method of measuring force, similar to a spring scale. A gravitational acceleration vector acting on a mass placed onto the device produces a force known as weight. The weight mechanically displaces the silicon platform and membrane which is transduced to an electrical signal where a change in capacitance is measured. Geometry of the silicon platform, membrane and glass well depth may be used to affect the linearity, sensitivity and range of measurement of the micro-scale.

摘要： A digital weighing scale is compensated for the effects of off-center loading by determining the position of the load and calculating a corrected weight value according to such position. Position sensing transducers are mounted on the load cell to provide information regarding the position of the load on the weighing scale. An expression for corrected weight as a function of load position and magnitude is determined for the particular scale and stored. The expression is used to calculate corrected weight according to the magnitude and position of each weight placed on the scale. The load cell may include a counterforce of substantially any type including single bending beam, dual bending beam or capacitive structure, and the load magnitude and position sensors may be of substantially any type including strain gages and capacitive sensors.

摘要： A transmitter senses a process variable and provides a two-wire output adjusted by a span adjustment. The transmitter has a sensor which senses the process variable and provides a sensor signal. An output circuit provides a two-wire output representative of the sensed process variable. A span-controlling circuit is coupled between the sensor and the output circuit and receives a span adjustment. The span-controlling circuit includes an amplifier coupled to a potentiometer which adjusts the span based on the span adjustment. The wiper of the potentiometer is connected to the amplifier output so that one portion of the potentiometer resistance provides feedback from the amplifier output to the amplifier input. A second portion of the potentiometer resistance is coupled between the amplifier output and the output circuit. Both portions of resistance affect both the span and the resolution of the output. The arrangement provides an improved resolution over a wide turn-down-ratio.

摘要： A scale comprising a stationary frame assembly, platform means arranged to move vertically upon receipt of some material thereon and at least one movable beam assembly, each movable beam assembly being coupled to the stationary frame assembly by a force sensing means which resists downward movement of the platform. The platform is coupled to the beam assemblies that are movable, and each movable beam assembly has a section for supporting a displacement sensing means thereon. Most preferably the displacement sensing means is an electronic sensing means adapted to move substantially horizontally for detecting movement of the movable beam assemblies that is transmitted through the platform means when the material is placed on said platform means, and said electronic sensing means produces a signal indicative of the weight of said material.
