Low Frequency Vibration Measurement Systems

VC and Nano Criteria System

This System is used for vibration measurements on very sensitive equipment, e.g. electron microscopes, photo-lithography equipment or microelectronics and nanotechnology equipment.

In order to standardize the installation and operating conditions of these systems, so called VC limits (Vibration Criteria) were developed in the 1980s. There are the levels VC-A to VC-G

The instrument measures the third-octave spectrum of vibration velocity with three channels. This allows measurement in three orthogonal directions (X/Y/Z) or at three different positions simultaneously
 

Seismic Accelerometer Set

The seismic accelerometer set is designed to measure low-frequency vibrations. Its high sensitivity makes it ideal for a wide range of applications. 

The seismic accelerometer set with 2-channel USB DAQ offers precise and reliable vibration measurements in a compact form.

The highly sensitive accelerometer has a measuring range of 10 V/g, allowing it to detect even the smallest vibrations. 

The software provides fast and accurate data analysis, making it suitable for various applications.

RogaDAQ2 + KB12VD Set

Portable Vibration Analyzer RogaDAQ2 VIB-E-220

Applications include scientific research, industrial monitoring and construction.

The second measuring channel enables the connection of an additional accelerometer.

Alternatively, an impulse hammer can also be connected to carry out structural investigations, e.g. on bridge or building structures.

The USB connectivity of our sensor system ensures that it can be easily plugged in and used without the need for complex set-up procedures or processes.

Scope of delivery:

RogaDAQ2 AC/DC Coupling Setting

The RogaDAQ2 USB DAQ is designed for the acquisition of DC voltages and, in conjunction with IEPE vibration sensors, for the precise measurement of extremely low frequencies from 0.3 Hz.

Two analog inputs can be controlled independently to switch the IEPE supply on or off. This feature allows users to connect different sensors to the appropriate channels for specific applications. 

For instance, an IEPE seismic accelerometer with a sensitivity of 10 volts per g can be connected to channel 1, while a DC-coupled magnetic field sensor can be connected to channel 2. This allows users to determine the optimal configuration for an MRI system.
