Power sensor cell remotely monitors pumps and process machine motors by using Ethernet communications. Hall effect sensors work on output of inverter drives. The device has a built in Ethernet control and communication-embedded web server that allows for scaling adjustments, setup of UDP (machine code) outputs through a port to a specific machine or to all machines that listen on that port. The system uses TCP/IP and UDP protocol with 10 Base T 10 Megabit Ethernet connection. The sensor has a 0-10 Volt DC analogue output, which can feed to a local monitoring display or to assist with troubleshooting.
