Vibration sensors are key equipment in monitoring the condition and performance of rotating systems, especially in sensitive industries such as oil and gas and power plants. In rotating systems with high moment of inertia, such as large steam and gas turbines, due to the low frequency range of vibrations, the use of speed transducers with appropriate sensitivity is essential. This study is dedicated to the design, simulation, and construction of a single-coil vibration sensor, which was developed with the aim of achieving a sensitivity of 10 mV/mm/s. The various components of the transducer, including the permanent magnet, coil, flat springs, and housing, were designed and fabricated using a reverse-engineering approach supported by detailed analysis of an existing commercial sensor. To determine the material and physical characteristics of the parts, experimental tests and field measurements were used, and modeling based on the law of electromagnetic induction was carried out to analyze the behavior of the sensor. Experimental results show that the produced sensor has an entirely linear voltage-velocity behavior with a sensitivity slope of 9.4374 mV/mm/s, which can be accurately compensated using a calibrated transmitter circuit. The operation of this sensor in the frequency range of 3 to 1200 Hz makes it a suitable option for use in heavy industrial conditions.
