The CMCP-575 Speed Transmitters are compatible with proximity probe or Hall effect inputs, they provide a 4-20 mA output proportional to the overall measurement. Each unit provides power for the associated transducer, processes the signal, and outputs a 4-20 mA dc current that is proportional to a user specified range such as 0-1,000 RPM. Combining transmitters with an existing PLC or DCS system results in a high density, low cost monitoring system.
