The new current sensors CT7812 (2 A) and CT7822 (20 A) are high-accuracy, finger-sized current sensors with excellent temperature stability, thanks to fluxgate technology. These sensors enable highly accurate current values to be measured by the modules U8556 or LR8536 (wireless) and recorded by the LR8450-series data logger. Due to their compact size, they can easily access wires even in the tight spaces of a vehicle's wiring box, making them suitable for simultaneous current measurements of multiple components. They also enable high-accuracy measurements for tasks such as assessing the appropriateness of fuse ratings and recording leakage currents when the EV is turned off.
In addition to the innovative current sensors mentioned above, Hioki offers a battery-operated and wireless module LR8536 that frees operators from complex wiring tasks, leading to reduced labor. Furthermore, the data logger LR8450-series can accommodate modules for acquiring not only current data but also temperature, strain, CAN signals, etc. This wide range of choices allows for the simultaneous, long-term recording of various data such as component temperatures, air conditioning, and shaft rigidity (more info).
