Abstract
The invention relates to a micro hardness tester (durometer) having a penetration body such as a point or the like penetrating into a sample under load. An electrical means is provided for loading the penetration body and the bearing force of the penetration body is convertible into electrical signals for the purpose of measuring said force. The invention is characterized in that the penetration body is fixed to an arm or spring arranged on a mounting element which spring or arm also carries at least one strain gauge or a micro dynamometer cell for measuring the bearing force of the penetration body.
Claims11
A micro hardness tester comprising:
- a penetration body for penetration into a sample under load;
- a spring arm having first and second ends and along which the penetration body is mounted;
- an electrical means for controllably loading the spring arm at a loading position on the spring arm, the loading position being spaced apart from the penetration body and from the first and second ends of the spring arm;
- a mounting element to which the spring arm is attached at the first end, the mounting element being pivotably arranged on a sample carrier that is mounted for rotation about vertical and horizontal axes and moveable along two perpendicular horizontal axes to permit displacement of the sample in horizontal directions x and y, rotation of the sample and tilting of the sample;
- means, mounted to the arm, for indicating the load on the spring arm thereby indicating the bearing force of the penetration body on the sample.
