1. Introduction element
model:BF350-3AA / 1.5AAGage Factor: 2.0Strain: 2%Grid wires: Longxwidth2x3.5mmSubstrate Size: lengthxWidth of 5x4.5mmSubstrate: Modified Phenolic substrate.The gate wire material: constantanResistance: 350 OhmFatigue life: 10000000Flux: ordinary solder rosinResistance strain gauge working principle is based on the effect produced by the strain, i.e., when the conductor or semiconductor material mechanical deformation under the action of the external force which changes corresponding to the resistance value, a phenomenon known as "strain effect."The strain gauge attached to the object to be measured, so that as the strain to be measured is bent together so that the metal foil on the inside with a bending strain. Many metal during mechanical bending resistance changes accordingly.
2. Introduction
- Voltage: 5V
- ~ Reverse diode protection (to prevent the reverse power)
- Board with a blue LED power indicator
- Analog Output
- The bending angle of 0-30
- The higher the voltage the greater the curvature of the output
- With zero potentiometer
- Potentiometer may regulate the output voltage of the starting
- Analog voltage output 0-3.5V
- Board size: 32 X 17 mm
- Behind the printed board output pin definitions
(Bending strain gauge can change the output voltage)
Q: how to use this principle?
This is the bending sensor
The principle is called, in terms of detecting the bending, the strain gauges attached on a carrier, such as: iron aluminum plastic carrier sheet then bent, to detect the bending strain gauge output voltage will change.
The strain gauges can be attached to the object, detecting the bending, and bending the module we converted voltage.
