本発明は、主として秤に用いられるロードセルに関し、
該ロードセル゛の耐久性の向上を図るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a load cell mainly used in a scale.
The purpose is to improve the durability of the load cell.

る必要がある。This type of load cell is configured to electrically detect the amount of strain in a strain-generating body corresponding to an applied load using a L/in gauge attached to the strain-generating body.
In order to improve the durability or maintain the performance of the load cell, it is necessary to protect the strain gauge from water and moisture.

歪体の変形を妨げて荷重−歪特性を損なうという欠点が
ある。Conventionally, measures have been taken to cover strain gauges with a moisture-proofing agent such as silicone rubber or seal them with metal foil, but the former method is particularly useful in environments with a lot of moisture or greenhouses. As for scales, which are often used in
Although it has excellent moisture resistance, it has the disadvantage that the metal foil with poor elasticity prevents the deformation of the flexure element, impairing the load-strain characteristics.

久性の向上を図るものである。The present invention has been made in view of the above-mentioned conventional circumstances, and is directed to a load cell in which a strain gauge is adhered to a flexible portion formed on a flexure element. Because it is a very thin film, several thousand angstroms thick at most, it is highly flexible and elastic, and is characterized by being coated with a homogeneous, non-porous aluminum vapor-deposited film. This effectively protects the strain gauge from water and humidity without impairing the load-strain characteristics of the strain-generating body, thereby improving the durability of the load cell.
