IoT based force indicating system
Measurement of axial force is important in the periodic calibration of tensile, compression and universal testing machines.
Additionally, portable load measuring systems are also in high demand. Weighbridges also require similar solutions for properly capturing digitised data of load.
Technical blueprint:
We have designed a thumb sized universal load cell indication system that can be coupled to any load cell. The device is equipped with a 24 bit delta Sigma analog to digital converter that helps the user get readings up to 3-4 decimal places. However, enhanced resolution is accompanied with a higher variability at low values due to accumulation of noise signals. In the pursuit of increasing the signal to noise ratio and achieving a stable and good result, the reading is obtained from the mean value of 25 instantaneous measurements that increase the stability as well as the homogeneity of the measurements.
