Strain Gauge Bending Sensor Module Y3 Weighing Amplifier Module VERSI

Description: Model : BF350-3AA / 1.5 AA Sensitivity factor: 2 Strain limit: 2% Grid wire: longxwide2x3.5mm Base size: longxThe width of 5X4.5mm Base material: modified phenolic substrate. Grid wire material Resistance: 350 ohms Fatigue life: gt; times Flux: ordinary rosin solder The working principle of resistance strain gauge is based on the strain effect produced by mechanical deformation, namely the role of conductor or semiconductor materials in the external force when the resistance value changes, this phenomenon is called #34;strain effect #34;. The strain gauge is attached to the object to be measured, so that it is bent along with the strain of the measured object. A lot of metal in the mechanical bending of its resistance will change. Product Details: Voltage: 5V Two tube reverse protection ~ (to prevent the power supply connected to the back) On board with a blue LED power indicator Analog output The higher the bending degree, the higher the output voltage Zero potentiometer Can be used to adjust the output voltage of the starting voltage Output analog voltage 0-3.5V Board size: 32 X 17 mm The board is printed with pin output definition (bending strain gauge can change the output voltage) Q: how do you use this principle? This is the bending sensor Said the principle is also to detect the degree of bending, the strain piece affixed to the carrier, such as: Iron and aluminum plastic film and then bending the carrier, the strain gauge to detect the bending output voltage will change. The strain gauge can be affixed to any object, the bending is detected, and then the voltage of the module is bent. (welding strain films should not too high 300 degrees below the appropriate welding time of 3 seconds, please use the welding wire cord is appropriate)
