Functional Devices, Inc., has released the first completely EnOcean-based self-powered wireless current sensor. Current sensors monitor the status of electrical current flowing through a power line, and this latest sensor from Functional Devices — RIBXKJF-EN — wirelessly transmits this status and enables remote monitoring or linking the operation of one machine with another. (EnOcean technology represents a combination of miniaturized energy harvesting modules with ultra low power radio technology as the basis for innovative maintenance free wireless sensors.)
A notable features of this new sensor is that it generates its own power for both sensing and wireless communication. Eliminating wires simplifies installation, especially retrofitting existing buildings; the self-powering eliminates maintenance throughout the product’s life. Functional Devices engineer Rob Pinto explains, “Many customers want to interlock an exhaust fan with a dryer; however, the equipment is often some distance apart. With our self-powered wireless current sensor, integrators simply clip the wireless current sensor to the dryer’s power line and connect a wireless relay to the fan. This saves time, cost and the headache or hard wiring to remote locations.”
The Functional Devices wireless current sensor detects load currents ranging from 3 – 150 Amps and transmits radio signals via the interoperable EnOcean wireless standard. The radio signal is sent to a wireless relay/repeater that uses load current data to switch electrical loads up to 20 Amps. When combined with the relay, the wireless current sensor provides a turn-key “interlocking load” solution for existing buildings.
