■Product Description This product is a current detector designed to easily measure the signal current flowing through railway tracks, with the aim of quickly identifying faults in the electrical circuits formed by the rails and the locations of insulation failures. The current sensor is compact and lightweight, utilizing a pickup coil (induction coil) built into the tip of the sensor rod, and the sensor part is separated from the main body to facilitate easy operation and reading of measurements. There is also a portable, simplified version available (Product Name: Doctor Car Current). Various signal currents flow through railway tracks (rails) to control level crossings, signals, points, and more. These measuring devices are equipped with filters that have a narrow bandwidth and high attenuation to prevent interference from currents other than the ones being measured. This technology can be applied not only in the railway sector but also in other fields for current detection to ensure safety and for detecting leakage currents at insulation points.
