The IFM VKV021 is a compact vibration monitor designed for continuous machine vibration monitoring. It measures vibration velocity from 0 to 25 mm/s RMS over a 10 to 1,000 Hz frequency range. The unit provides one configurable PNP switching output and one 4–20 mA analogue output. Its 18–32 V DC supply and IP67 protection make it suitable for industrial machinery. The intuitive switch-point setting simplifies commissioning without requiring complex software configuration.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VKV021 is designed to monitor vibration according to DIN ISO 10816. Its measuring range is 0–25 mm/s RMS. The frequency range extends from 10 to 1,000 Hz. This allows the monitor to detect increasing machine vibration within the specified range. It is useful for early identification of abnormal machine operating conditions.
The monitor provides one digital switching output and one analogue current output. The digital output uses PNP technology and is normally closed in the factory configuration. The analogue output provides a 4–20 mA signal. This allows the vibration level to be used both for local alarm generation and PLC-based monitoring. The output arrangement supports straightforward integration into automation systems.
The VKV021 operates from 18–32 V DC and has a protection rating of IP67. Its MEMS sensing technology provides compact vibration measurement. The sensor is mounted using an M8 × 1.25 connection and a specified tightening torque of 15 Nm. The robust construction is suitable for industrial equipment. These features make the unit practical for machine-level vibration monitoring.

The VKV021 can continuously monitor vibration while the machine is operating. The 4–20 mA output provides a proportional signal for control-system monitoring. The switching output can be used for alarm generation. This allows machine vibration to be monitored without a separate diagnostic controller. The compact device is suitable for decentralised machine protection.
The intuitive setting concept simplifies adjustment of the vibration alarm level. This reduces the need for external configuration software for basic switch-point setup. The M8 mounting arrangement provides a defined mechanical connection. IP67 protection supports installation in industrial environments. The result is a straightforward vibration-monitoring solution for machine builders.
