Definition
- Noun:
- A device for measuring strain in a surface: A "strain gauge" is a sensor whose electrical resistance changes in proportion to the amount of strain (deformation) in the object to which it is attached. It is used to measure stress, force, pressure, and weight.
Usage Examples
- Noun:
- Engineers attached a strain gauge to the bridge's support beam to monitor for structural stress.
- The data from the strain gauge indicated that the material was nearing its elastic limit.
- Accurate measurement of the force required a highly sensitive strain gauge.
Advanced Usage
- "to install/apply a strain gauge": The process of bonding or attaching the sensor to a surface.
- The technician carefully applied the strain gauge to the aircraft's wing.
- "strain gauge reading/measurement/data": The information or output provided by the device.
- The strain gauge readings were transmitted wirelessly to the monitoring station.
Variants and Related Words
- Strain gage (n): An alternative spelling for "strain gauge," primarily used in American English.
- Load cell (n): A type of transducer often constructed using strain gauges to convert a force into an electrical signal.
- Extensometer (n): Another instrument for measuring deformation, but typically used for larger displacements over a gauge length.
Synonyms
- Stress gauge: A less common term for a device measuring mechanical stress, often via strain.
- Deformation sensor: A more general term for a device that detects changes in shape.
Related Phrases
- Wheatstone bridge circuit: The standard electrical circuit used with strain gauges to measure small changes in resistance.
- The strain gauge was connected to a Wheatstone bridge to obtain a precise voltage output.
- Gauge factor: A key parameter of a strain gauge that describes its sensitivity.
- Selecting a strain gauge with a high gauge factor improves measurement sensitivity.
