Abstract:
PROBLEM TO BE SOLVED: To provide a weighing apparatus having waterproofness and explosion-proof and capable of performing high precision measurement.SOLUTION: An upper case 80 has a release opening 811 on the upper surface. An inner case 70 has an upper surface opening 711 with a load bearing member 401 sealed by a diaphragm on the upper surface and a side opening 720 covered by a waterproof dust resistant air permeable member. The upper surface of the inner case 70 has a guiding groove 712 for guiding a liquid entered from the release opening 811 to the side face where waterproof and explosion-proof are not available. The explosion-proof is secured by the upper case 80 and the lower case 60, and the inner side of the inner case 70 stored with a measurement mechanism 40 has the water-proof protected. Since a vent hole 720 is provided on the side face of the inner case 70, a sufficient vent hole area can be secured. Since the liquid entered from the release opening 811 is guided to the side face of the inner case where the waterproof dust resistant air permeable member is not available, an adhesive agent used for adhering to the inner case 70 of the waterproof dust resistant air permeability member is not deteriorated.
