Temperature Estimation Using Infrared Thermal Imaging Camera and Temperature Sensor Probe in the Electromagnetic Diaphragm Pump

The electromagnetic diaphragm pump system, which includes electromagnets, permanent magnet, membrane, valves, and chamber, has electromagnetic forces that act to move the permanent magnet positioned above the thick rubber layer driven by magnetic polarization. The flow and pressure control are achieved with a digital cabinet. This study proposes a novel approach that uses a temperature sensor probe and an infrared thermal imaging camera to measure the temperatures of an electromagnetic diaphragm pump. The results show a good agreement between the infrared thermal imaging and temperature sensor techniques, confirming that the proposed technique could accurately estimate the temperature. The temperature varies as a function of the liquid pumped in the electromagnetic pump system, and as a result an equation model is proposed to express the formulation dependence between temperature, the switching speed of the permanent magnet and the pumped liquid.
