Abstract: A load detection sensor capable of stably weighing a heavy object to be weighed in high precision. The load detection sensor according to the present invention includes a force sensor including a tuning fork vibrator and a block body that has a rectangular parallelepiped outer shape and transmits an applied load to the force sensor by using a lever to reduce the load. It is characterized in that the block body contains therein a lever mechanism and a Roberval mechanism by working on the longitudinal side thereof and that the force sensor is coupled to the side of the block body. Although the block body is cut and ground in the side for fabricating the lever mechanism and the Roberval mechanism, it maintains the rectangular parallelepiped outer shape and sufficient mechanical strength, thereby enabling to stably reduce the applied load.

Abstract: A force sensor apparatus includes a vibrating beam and first and second isolator mass members that supports ends of the vibrating beam. The first and second isolator mass members are configured symmetrically relative to an axis that intersects the vibrating beam at an angle other than 90 degrees. First and second end mounts connect respectively to the first and second isolator mass members. Each isolator mass member has a center of gravity. Each isolator mass member is shaped so that it can be massive (e.g., along the x-axis direction) while at the same time having its center of gravity at an optimal location so that undesirable beam forces and moments that would otherwise transfer vibrating beam energy to the end mounts are cancelled.

Abstract: A reactionless single beam vibrating force transducer utilizes counterbalances at opposite ends of the beam that rotate in directions opposite to the ends of the vibrating beam to reduce rotational and normal forces transmitted to the end supports for the beam. The proportions of the counterbalances relative to the size of the beam may be chosen to reduce forces in a direction normal to the beam to zero at the expense of some rotational moments at the end of the beam support, or to reduce moments at the expense of some normal force. The relative amounts of residual rotational moments and normal force can be adjusted to suit particular applications. Flexures may also be utilized to reduce the rotational moments transferred to the beam support even further.

Abstract: An apparatus for measuring a force or load comprising a vibratory beam which vibrates back and forth at a resonant frequency. The beam has first and second end nodal points and first and second ends adjacent to the first and second nodal points. The first end of the vibratory beam is coupled to the load for applying a stress to the vibratory beam that determines the resonant frequency at which the beam vibrates. In addition, masses are coupled to the beam intermediate of the first and second ends. The masses are arranged symmetrically on opposite sides of the beam and reciprocate at the resonant frequency. The reciprocatory masses are located at a position along the beam at which the greatest back and forth vibration of the beam at the resonant frequency occurs. Alternatively, a pair of vibratory beams are provided. The beams are coupled together at opposite ends to form a tuning fork, each beam having a portion which vibrates back and forth at a resonant frequency. Masses are coupled to these portions of each of the beams, the masses being arranged symmetrically relative to each beam and reciprocating at the resonant frequency.

Abstract: The invention relates to a weight measuring apparatus utilizing a vibration type force sensor having a greatly increased Q and being inexpensive and easy to manufacture. The force sensor includes a single vibratory beam or a pair of vibratory beams, which oscillate at a particular measurement frequency related to the stress applied to the sensor by a weight. A rotational mass is coupled to a nodal point of the vibratory beam at the measurement frequency, and greatly influence the frequency at which the beam will vibrate. As a result, the tolerances for manufacture of the force sensor are greatly relaxed, and the pendulum-like movement of the rotational masses for a double-ended tuning fork type sensor tends to override any mismatch between the two parallel vibratory beams.

Abstract: A vibration type force detector in which the vibration string is made of a platinum-based nickel-containing alloy. The magnitude of a force to be detected is obtained through the measurement of a natural vibration frequency of a string vibrating with the force loaded thereto. However, the force detector using a Pt-Ni alloy vibration string based on the invention makes it possible, for the first time, to apply a vibrational type force detector to a precision measurement of force or weight. Measurement with an accuracy of 10.sup.-5 is made possible by the present invention.

Abstract: A method and apparatus for measuring force or other parameters and temperature. The apparatus includes an oscillator and a vibratory element, such as a quartz crystal, which is caused to resonate by the oscillator at two frequencies f.sub.1 and f.sub.2 selected from the fundamental frequency and its overtone frequencies of the vibratory element. The vibratory element is selected so that the two frequencies f.sub.1 and f.sub.2 both vary with variation in force (or other parameter) applied to the element and with variation in temperature of the element, and so that the magnitude or scale factor of variation for frequency f.sub.1 is different from that for frequency f.sub.2. The apparatus also includes a detection device for detecting the frequencies f.sub.1 and f.sub.2 and for producing signals representing the frequency variation of the two frequencies relative to a reference frequency, and a processor for processing the signals produced by the detector device for determining the force (or other parameter) and temperature to which the vibratory element is subjected.
