Development of a Wireless Weighing Transducer and its Calibration

This article presents research results concerning a weight transducer equipped with a WiFi interface. This solution enables conducting remote measurements of force in hard-accessible places where measurements with the use of a USB module are not possible. Additionally, the paper contains a description of a device calibration process during which the measured quantity is established. This is conducted by converting the voltage measured on an ADC transducer into the measured quantity in the form of force. Moreover, the influence of the accuracy of the calibration test bench construction on the obtained measurement results is shown. The research outcome, covering the calibration process and determining the measurement errors, and appropriate conclusions are presented in the form of tables and graphs.
