Dual-Output Vibration Sensors – Two Output Signals for Flexible Vibration Analysis
Dual-output vibration sensors are specialized devices for measuring vibrations and oscillations that provide two different output signals simultaneously. This combination enables particularly flexible use of measurement data for monitoring, analysis, and control.
Typically, dual-output sensors provide, for example, a dynamic output signal (e.g., IEPE) for detailed vibration analysis, as well as a low-frequency or DC signal (e.g., 4–20 mA) for continuous condition monitoring.
These sensors are mainly used in industrial applications where both high-resolution vibration analysis and simple process monitoring are required. They offer an efficient solution to cover multiple measurement requirements with a single sensor.
How Dual-Output Vibration Sensors Work
Dual-output vibration sensors detect mechanical vibrations and convert them into two separate electrical output signals that serve different requirements.
The measurement principle is usually based on piezoelectric sensing elements that convert vibrations into electrical signals. The internal electronics process the signal and provide it in two forms:
- Dynamic signal (e.g., IEPE output)
For detailed vibration analysis with a wide frequency range - Process signal (e.g., 4–20 mA or voltage)
For continuous monitoring and integration into control systems
This dual-output functionality makes it possible to support both condition monitoring systems and traditional process control systems in parallel.

How to Choose the Right Dual-Output Vibration Sensor
Selecting a suitable sensor depends on the specific requirements of the application, especially when multiple output signals are needed.
- Type of output signals
It is crucial to define which signals are required—for example, IEPE for analysis and 4–20 mA for process monitoring. - Measurement range and frequency range
The sensor must cover both the relevant vibration frequencies and the required amplitude ranges. - Sensitivity and signal quality
High signal quality and good noise performance are essential for precise diagnostics. - Integration into existing systems
Compatibility with data acquisition systems, PLCs, or monitoring platforms is an important factor. - Environmental conditions
Temperature, humidity, dust, or chemical influences must be taken into account. - Mounting and installation
The mounting method affects measurement quality and should be suited to the application.
