FluxDAQ+ Heat Flux Sensor and Thermocouple Measurement and Data Logging System The FluxDAQ+ is a low-cost Arduino based data acquisition system that is designed to accurately measure the small analog DC voltage output signals from PHFS heat flux sensors, their integrated thermocouples and independent...
During tests, the output voltage signal produced by each sensor was directly recorded using an Arduino Mega board connected to the acquisition interface. The data acquisition process was performed via the PLX-DAQ software communicating with an Arduino application for processing the outputs and the ...
The loadcells are connected to the analog pins of the Arduino. This is also the case for the pressure sensors; however, they use the I2C protocol, so the use of a multiplexer was necessary in order to address every sensor separately. All the sensors are carefully calibrated and programmed ...
The heat partition through the chips does not seem to remove more than 4% of the overall heat flux, and most of the generated heat in the edge grinding of GFRP with low depth of cut is dissipated through the work part and the diamond tool. In order to end up at significant and ...
Nevertheless, the time delay introduced by the LM35 sensor is only of a few seconds and the effect on the measurement and the closed loop control can be neglected. Therefore, it was decided that the LM35 was the appropriate choice of sensor for the prototype. Both sensors were installed as ...
