Strain Checker FGMH Series
Ordinary strain gauges measure the strain generated in a structure through adhesive, while strain checker (FGMH-1/FGMH-2A) is directly pressed against the structure with the attractive force of a magnet to measure the strain by the friction produced at the interface. Strain is easily and immediately measured by directly attaching the strain checker to a position of interest. The FGMH-1B is standard type strain checker with smallness and lightness and the FGMH-2A is strain checker specified for application in narrow space such as welding part.

Features
- Using friction
Fixed to a structure by magnet and strain measured by friction produced on the surface. - No adhesive needed
Removal of paint, grinding, degrease, adhesive bonding and curing are unnecessary. Measurement gets ready by only attaching the strain checker. - Painting after measurement not required
Measurement can be made without taking off the paint of a test object. - Reusable
Due to easy mounting and dismounting, measurement position can be easily moved. In combination of TML dynamic strain recorder DC-204R, it is possible to detect a position of the largest strain being generated by moving. - Simultaneous multi-point measurement
Several strain checkers can be used at the same time for finding stress distribution and principle stress direction.
