PR 4225 Universal f/l-f/f Converter

$301.00

Frequency converters are useful for protecting rotating machinery by monitoring critical speed, over speed, and under speed. Commonly used with synchronous motors that turn or vibrate, frequency converters can also match new speed sensors to original units and control process temperature, pressure, or flow without the use of a separate controller.
