The IFM VNB001 is a vibration sensor designed for direct machine vibration monitoring and condition assessment. It measures vibration velocity from 0 to 500 mm/s depending on vibration frequency and covers 2–1,000 Hz. The device provides two switching outputs and one scalable 4–22 mA analogue output. Its display allows vibration values and alarm states to be viewed directly at the machine. USB communication supports configuration and data access for maintenance and diagnostics.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The VNB001 uses a capacitive MEMS-based measurement principle. It measures vibration over a range of 0–500 mm/s depending on vibration frequency. The frequency range is 2–1,000 Hz. RMS measurement is used in the factory configuration. This allows the device to provide a direct indication of machine vibration behaviour.
The VNB001 provides two digital outputs for pre-alarm and main-alarm monitoring. The analogue output provides a 4–22 mA signal. The factory pre-alarm point is 2.8 mm/s and the main alarm point is 4.5 mm/s. The output settings can be configured for the application. This provides both local alarm functionality and continuous signal transmission.
The VNB001 provides direct display and recording functionality at the machine. USB communication allows connection to a computer for configuration. It includes self-test and Heartbeat functions for additional diagnostics. IP67 protection supports industrial machine installation. The -30 to 60°C operating range supports a wide range of equipment environments.

Maintenance diagnostics
The VNB001 provides vibration information directly at the monitored machine. Its display reduces the need for a separate local measurement instrument. The two alarm outputs allow early and main warning levels to be separated. The analogue output can transmit the vibration value to another control system. This makes the sensor suitable for decentralised condition monitoring.
USB communication provides access for configuration and analysis. Self-test and Heartbeat functions support device health monitoring. The 4–22 mA output can be integrated into automation systems. IP67 protection supports industrial installation. These functions make the VNB001 suitable for preventive and predictive maintenance strategies.
