What is strain gauge load cell?
Strain gauge load cells usually feature four strain gauges in a Wheatstone bridge configuration, which is an electrical circuit that balances two legs of a bridge circuit. The force being measured deforms the strain gauge in this type of load cell, and the deformation is measured as change in electrical signal.
How thick is a strain gage?
Gauge factor Foil gauges typically have active areas of about 2–10 mm2 in size. With careful installation, the correct gauge, and the correct adhesive, strains up to at least 10% can be measured.
Which metal is used in strain gauge?
Metal strain gauges The copper-nickel alloy is among the commonly used materials. Unlike semiconductor strain gauges, metal strain gauges change their resistance due to geometry changes. Although metals also show some piezoresistive effects, they are usually very small compared to those of semiconductors.
What can a strain gauge load cell be used for?
A strain gauge load cell can be manufactured in a variety of configurations to measure compression, tension or bi-directional forces. Our strain sensor, model XT50, is used to measure elongation in structures in such applications as on-board weighing, vehicle stability control and elevator overload systems.
How many strain gauges are made per year?
To ensure that our strain gauge load cells are highly precise and reliable, Flintec have a dedicated facility manufacturing strain gauges for use across our sensor range, with approximately 5 million made each year. What is a strain gauge?
Can a foil strain gauge be used on stainless steel?
Our years of experience in using load cell strain gauge configurations means we are able to apply foil strain gauges to different types of material. We can help customers who require a strain gauge bonding service for objects of varying shape and size that use materials such as aluminum, steel and stainless steel.
How are strain gauges used in force sensors?
A strain gauge, sometimes referred to as a strain gauge, is a bonded resistive foil sensor whose resistance changes with applied force. Our load cells and force sensors typically use four strain gauges arranged in a Wheatstone Bridge.
