The structure allows for the strip to be bent in either direction with travel limiters to prevent damage.
Ideal for showing the principle of a metal foil resistive strain gauge.
The device is bonded to a flexible plastic strip with connections brought out to 4mm sockets.
The gauge has a resistance of 120 ohms and gives about 1 ohm change at maximum flex.
For real measurements the unit would need to be used as part of a bridge network with suitable amplification.
A step gauge is provided to enable the strip to be bent in 5mm increments.
