Abstract: As a weighing device which can not only make water and dust less likely to reach the sensor unit, but also simply discharge water having reached that position if any, and which further can improve the maintenance workability of water-washing of the sensor unit, an electronic balance includes a weighing pan, a load cell that measures a load of a measuring object placed on the weighing pan, and a scale main body case that supports the load cell. The load cell is disposed outside and over the scale main body case, a cylindrical transparent cover that covers the whole side face of the load cell is integrally provided for the weighing pan, and the lower end of the transparent cover is disposed with a clearance over an upper face of the scale main body case.

Abstract: A low-cost, compact, high-precision axial force sensor is provided. The axial force sensor includes a pair of parallel pressing plates and a strain gauge sandwiched therebetween. The strain gauge includes a plurality of strain-sensitive resistive elements around its periphery, and is provided with a spacer that transmits a pressing force from the pressing plates to some of the strain-sensitive elements but blocks the pressing force to the rest of the strain-sensitive elements. The output signal of the strain-sensitive elements blocked from the pressing force provide an accurate baseline to compare the output signal of the strain-elements subjected to the pressing force. The spacer has a uniform pattern of open and closed portions. On the strain gauge, the strain-sensitive elements are provided at both the open and closed portions of the spacer.
