For that we ordered a LabJack U3-LV along a with an amplifier (datasheet) and a belt which is some kind of strain gauge I think. They are attached using adhesives to the object which is under application of force. Optical strain gauges (also called fiber optical (strain) sensors or FOS, optical (strain) sensors or Fiber Bragg Grating sensors) are used to measure strain, but can easily be integrated into different types of transducers, such as in temperature, acceleration or displacement. Instrumentation signals (for example from Wheatstone bridge sensors) are often in the order of mV (millivolts) or less, and need to be amplified for processing via ADC. To use it with Arduino we are using our HX711 digital bridge sensor interface module. It’s used mainly for machinery applications and objects that have curved surfaces. The, ST recently announced a partnership with Sanken, a Japanese company specializing in power modules, and we wanted to explore one.
