Battery-less wireless current sensor

Measurement data from a 3-channel current sensor can be collected wirelessly and without batteries using EnOcean.

URD Co., Ltd. is a specialized manufacturer of current sensors and power-related equipment, established in 1973 in Yokohama City, Kanagawa Prefecture. The current sensors have numerous adoption records in Japan, and in addition to approximately 600 types of current sensors, the company also supports the development of various application products and custom items. The battery-less wireless current sensor developed by the company uses EnOcean for device communication, allowing for wireless collection of measurement data from current sensors without the need for batteries.

basic information

■ Features 1. Power supply from the measurement cable to the wireless current sensor (energy harvesting) 2.
