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.
Frequency converters can be used to verify other tachometers and offers an independent alarm for critical, over, and under speed. Reliable speed monitoring improves processes by ensuring accurate performance while decreasing equipment wear and downtime. Additionally, the frequency converters can transmit speed to an HMI control or PLC unit for data logging and more.
To maintain a safe working environment and improve safety ratings, the 4225 universal f-l/f-f frequency converter can be used to measure equipment speed in addition to the existing tachometers that monitor critical functions. Having redundant speed monitoring increases the reliability of the system by providing a backup source for process data if the primary tachometer fails and ensures accurate measurement of rotation speed.
Frequency converters measure the rotation of rotary machinery such as a generator, compressor, or gas turbine then generates a frequency that can be used to control pumps, fans, etc. By directly controlling equipment with the speed of rotation, systems can be synchronized thus increasing safety, reducing operating costs, and minimizing wear on equipment.
Frequency converters allow various instrumentation to communicate together by converting an AC frequency to a DC frequency. Through the use of a frequency converter, AC outputs from equipment like an engine can directly be used to signal operating conditions for other instrumentation, such as a fan that requires a DC frequency input.
Since many types of instrumentation require a DC input, frequency converters are commonly used in industrial processes, manufacturing, and power utilities to allow equipment to work as an integrated system.
