The IFM VSA004 is a high-performance vibration sensor engineered for accurate detection and monitoring of mechanical vibrations in industrial machinery. Built with a wide measuring range, capacitive sensing principle, and robust cable design, it plays a crucial role in predictive maintenance and machine protection strategies.

One of the defining features of the VSA004 is its measuring range of -25…25 g, coupled with a frequency response of 1…10,000 Hz. This broad coverage enables the detection of both low-frequency structural vibrations and high-frequency anomalies such as bearing damage or imbalance. By monitoring these dynamic conditions, operators can identify early warning signs of machine wear and prevent costly failures.

The sensor employs a capacitive measuring principle, known for its accuracy and sensitivity. This design ensures reliable detection of small vibration changes, making it particularly effective in precision machinery and critical process applications. Its ability to provide consistent measurement over a wide range of operating conditions enhances process transparency and supports condition-based maintenance strategies.

Mechanically, the VSA004 is equipped with a rugged cable system engineered for industrial reliability. The cable is halogen-free, making it suitable for applications requiring compliance with strict fire safety standards. It is also screened to minimise electromagnetic interference and ensure clean signal transmission, even in electrically noisy environments. Furthermore, the cable is drag chain compatible, guaranteeing long service life in dynamic machine applications where continuous movement and flexing are required.

The VSA004 is specifically designed for connection to external IFM VSE diagnostic electronics, which analyse the raw vibration signals and provide actionable diagnostic data. This setup allows for advanced condition monitoring, enabling operators to evaluate machine health in real time and implement predictive maintenance strategies. When integrated into a monitoring system, the VSA004 helps reduce unplanned downtime, extend machine life, and improve overall plant efficiency.

Operating within a voltage range of 7.2…10.8 V DC, the sensor is designed for straightforward integration into industrial systems. Its low power consumption ensures efficiency, while its durable design supports long-term use in demanding environments such as manufacturing plants, rotating machinery, and process automation systems.

Typical applications of the VSA004 include monitoring pumps, compressors, fans, motors, and gearboxes—equipment where vibration is a critical indicator of performance and wear. By detecting imbalances, misalignments, and bearing faults at an early stage, the sensor helps maintain production reliability while reducing maintenance costs.

In summary, the IFM VSA004 is a robust and precise vibration sensor combining a wide -25…25 g measuring range, capacitive sensing principle, industrial-grade cable design, and compatibility with IFM diagnostic systems. Built for reliability and predictive maintenance, it delivers the performance and durability required for effective vibration monitoring in industrial applications.
