    摘要: A flow rate sensor for performing a flow rate detection of fluid with high accuracy without suffering adverse effect of the environmental temperature condition even when the fluid is viscous fluid having relatively high viscosity or the flow rate is relatively small is provided. The flow rate sensor includes a flow rate detector having a heating function and a temperature sensing function, and a pipe line for fluid to be detected which is formed so that heat from the flow rate detector is transferred to and absorbed by the fluid. The temperature sensing which is affected by a heat absorption effect of the fluid due to the heat is executed in the flow rate detector, and the flow rate of the fluid in the pipe line is detected on the basis of the temperature sensing result. Unit retaining portions formed on a casing in which the pipe line is formed, the unit retaining portions being disposed adjacent to the pipe line. A flow rate detecting unit comprising the flow rate detector is retained by the unit retaining portion, and a temperature detecting unit comprising a fluid temperature detector is retained by the unit retaining portion.

    摘要: A force measuring device mainly used as a weighing device, comprising first and second horizontal cantilever members disposed parallel with each other in a common vertical plane, a weighing cradle attached to the free end of the first member, and a metal string stretched between the free ends of both members. The string is placed between a pair of magnetic poles so that it vibrates at its inherent frequency functionally relating to its tension and, therefore, a load applied to the weighing cradle. The frequency of the string is measured and the value of the applied load is calculated therefrom by an electronic calculating circuit. In order to overcome a problem of frequency deviation caused by variation in the spring constants of both cantilever members due to variation in the surrounding temperature, the inventive device includes a temperature sensor and arithmetic circuitry for applying compensation for the error due to the temperature change to the calculation of the applied force.

    摘要: The weighing apparatus according to the invention is for use on a support surface which is subject to vibration. The apparatus includes a base adapted to be positioned on the support surface and having opposing first and second sides. The base is adapted to transmit vibrations from the support surface. A tray holds the product to be weighed and has a center of gravity adjacent the first side of the base. A load cell supports the tray on the base at the first side of the base. Strain gauges connected to the load cell generate a signal indicative of the weight of the tray and any product held thereby. The signal includes oscillating noise corresponding to vibrations transmitted by the base through the load cell to the tray. An auxiliary beam and counterbalance weight stablize the tray by minimizing at least some of the vibrations transmitted to the tray and by converting at least some of the lower frequency vibrations transmitted to the tray into vibrations having a frequency which is higher than the frequency of the lower frequency vibrations. The tray transmits reverse-phase vibrations to the load cell which result in noise in the signal. The auxiliary beam and counterbalance converts at least some of the reverse-phase vibrations transmitted to the load cell into vibrations having a frequency which is higher than the frequency of the reverse-phase vibrations.
