PRODUCT DESCRIPTION
A strain gauge is a device that measures how much an object is stretched or compressed. This module uses the BF350-3AA strain gauge, which has a built-in amplifier and a potentiometer to adjust the measurement results.
A strain gauge is a type of sensor that changes its electrical resistance when it is subjected to force. It can measure force, pressure, tension, weight and other quantities by converting them into electrical signals.
A strain gauge operates based on the principle of electrical conductance and how it depends on the shape of the conductor. When a conductor is stretched or compressed within its elastic limit, it does not break but becomes thinner and longer or thicker and shorter. This changes its electrical resistance, which can be measured by a circuit.
Features:
- Two tubes of reverse protection ~ (to prevent the power supply from 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.
