This S-Type load cell can convert up to 200kg of pressure (force) into an electrical signal. Each load cell can detect changes in electrical resistance as a result of the strain (pressure or force) applied to the form. This gauge can be used to measure how heavy an object is, if its weight changes over time, or simply to detect the presence of an object by detecting strain or load applied to a surface.

Each straight bar load cell is made of alloy steel and can hold up to 200 kg. In these load cells, four strain gauges are coupled in a Wheatstone bridge design. On the connection wiring, red denotes E+, green denotes O+, black denotes E-, and white denotes O-. Furthermore, these load cells have an IP66 protection certification and two M4 and two M5 sized through-holes for attachment.

A force-sensing resistor is a material whose resistance changes when a force, pressure or mechanical stress is applied. They are also known as force-sensitive resistor and are sometimes referred to by the initialism FSR. Play media. The Ohmite FSR Series (Force-Sensing Resistors) exhibit the unique characteristic of dynamic resistance related to the amount of applied force. In general applications, the more force applied to the surface of the sensor, the lower the resistance. The resistance change is inversely proportional to the applied force. At their core, Force Sensing Resistors are devices that produce a decrease in electrical resistance as more physical force or pressure is applied to them—putting them in the broader category of piezo resistive devices.

Applications:

• Airbag sensors
• Human-Machine Interface (HMI)
• Machine-Machine Interface (MMI)

A strain gauge is a device used to measure strain on an object. This strain gauge module uses the strain gauge BF350-3AA, it has an onboard amplifier and potentiometer to adjust the measured results

A Strain gauge is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured
