摘要: A weight sensor includes a deformable body, a first strain resistor provided on an outer side surface of the deformable body, and a pressing member applying a load to the deformable body. The deformable body includes a tubular portion having a tubular shape extending along a center axis and surrounding the center axis, and a projection projecting from an inner surface of the tubular portion. The pressing member moves along the center axis so as to apply a moment to the tubular portion. The resistances of the strain resistors change greatly, allowing the weight sensor to measure a load with high sensitivity.

摘要: A non-contact position sensor includes a magnet, magnetoresistive elements arranged on a line extending in a predetermined direction on a pole surface of the magnet with predetermined intervals, and an object made of magnetic material displaceable in the predetermined direction. The magnetoresistive elements are connected serially between a power supply and a ground. A first magnetoresistive element is connected to the second magnetoresistive element at a first node. A second magnetoresistive element is connected to a third magnetoresistive element at a second node. The object includes a projection and a shaft connected to the projection. The projection can face the first to third magnetoresistive elements. The shaft is located away from the pole surface by a distance longer than a distance between the projection and the pole surface of the magnet.

摘要: In a liquid level sensor according to the present invention, a first detecting electrode being always in a liquid to be measured, a second detecting electrode which measures a level of the liquid to be measured, and a third detecting electrode being always out of the liquid to be measured are arranged, an operation of charging capacitor 45 for a time being in proportion to a ratio of a length of a part of the second detecting electrode in the liquid to be measured to a total length of the second detecting electrode and an operation of discharging the electric charge of the capacitor for a time being in proportion to a ratio of a length of a part of the second detecting electrode being out of the liquid to be measured to the total length of the second detecting electrode is repeated. With this configuration, the liquid level can be precisely detected without arranging a complex operational device even though a dielectric constant or a temperature of the liquid to be measured changes.
