* Question
| What are the characteristics of metal foil strain gauges and silk strain gauges? |
* Answer
| Compared with the wire strain gauges, the metal foil strain gauges have the following characteristics.1 The metal foil grid is very thin, so the stress state it feels is closer to the stress state on the surface of the test piece.2 The foil has a large surface area and good heat dissipation conditions, so it is allowed to pass a large current, so that a larger signal can be output, and the measurement sensitivity is improved.3 The size of the foil grid is accurate and uniform, and can be made into any shape, especially for the production of strain gauges and small gauge gauges, thus expanding the use of strain gauges. |
