Title:
台秤及び荷重検出ユニット
Document Type and Number:
Japanese Patent JP5575128
Kind Code:
B2
Abstract:
A platform scale for weighing an object to be weighed by supporting it by a plurality of load detection sections, wherein the load detection section comprises a load sensor 40 having a block body 42 for transmitting an applied load to a tuning fork vibrator 41 coupled to the block body 42 by reducing the load, a circuit board having fabricated thereon circuitry for converting a signal from the tuning fork vibrator into a digital signal and a sensor case 33 for accommodating the load sensor and the circuit board. The sensor case 33 is made by casting stainless material by a lost wax process and is directly coupled to parallel base frames 20 for maintaining the distance between the base frames. The sensor case has sufficient mechanical strength and also acts as a structural member for the base frames, thereby reducing the number of components and the height of a weighing table.
