Abstract

This paper presents a real-time force measurement system of the pressing machine with a pressure sensor in the cylinder. It is an indirect measurement method of force with a pressure sensor in the cylinder. The air pressure is measured in the cylinder and also the voltage of the pressure sensor is measured. After that, the measured voltage is transformed into force by the equation from the experiments. The advantage of this method is that it can reduce the wasting time in the production process, resulting in increased productivity. The results of the force measurement comparing with the reference device (load cell) showed that performing force measurement experiments using the developed system compared to that of the load cells (reference device) at the battery pressing machine. The minimum error is 0.010% and the maximum error is 0.687%. Moreover, the results from the PCB connection pressing machine found that the minimum error is 0.043% and the maximum error is 1.768%. For the monitoring of the real-time force, the system showed the results of the force measurement in the website developed using PHP, HTML, JavaScript and Ajax. The results showed that the measured forces obtained the developed system were close to the measured force from the reference device (load cell) and it could measure and display the results in real-time.
