Vibration Diagnostics Services
Independent expertise in vibration diagnostics for critical infrastructure
Since 1988, Vibro-Consult AG has analyzed vibrations of more than 1,200 machines and equipped over 250 with advanced monitoring systems worldwide. We make this extensive experience available to customers in the power generation and industrial sectors around the globe. As an independent and certified company, Vibro-Consult ensures the highest standards in measurement technology and machine diagnostics.
Your specialist in vibration-based machine diagnostics
It provides valuable input for monitoring and meeting key operational requirements of the power plant. The VC Fingerprint focuses on the following objectives:
VC Fingerprint
Get to know and assess the running behavior of
the machine group in the entire load range.
​
Assess the current condition.
​
Determine the causes of abnormal behavior of
the machine group.
​
Make customized adjustments to the vibration
monitoring system, taking into account the safety
requirements, the running behavior, the standards
and the operational situation.
Reduction of mechanical unbalance
A highly efficient and well-established method to reduce vibrations and mechanical forces acting on the machine. This is achieved by applying suitable balancing masses:
VC Balancing
Significantly improve the smooth running of the machine.
​
Reduce undesirable rotating forces that place unnecessary stress on bearings, pedestals,
foundations, rotor and housing structures, piping, etc., thereby preventing potential
damage.
​
Prevent shaft bending and thus reduce the risk of contact with stationary components.
Fast and precise root cause analysis of vibration issues
Unexpected vibrations on turbines, generators, or pumps can lead to costly downtime and damage.
With state-of-the-art measurement technology and decades of field experience, Vibro-Consult analyzes the root causes directly on site – independently, efficiently, and with clear focus.
​
By comparing the data with reference measurements (e.g. VC Fingerprints), unbalance, resonance, bearing defects, or assembly errors can be reliably identified. The results are translated into clear recommendations and, if required, immediate corrective actions.
VC Troubleshooting
The goal: minimize downtime, restore operational safety, and ensure long-term reliable machine performance.
The wide range of challenges in a power plant often requires specialized measurements to obtain the necessary information. Vibro-Consult AG offers additional services such as:
Special Diagnostics (on-demand)
Torque measurements (contactless or via telemetry)
​
Tensile measurements (via telemetry)
​
Noise measurements
​
Modal analyses
​
Vibration measurements during blasting
​
Winding head measurements, impact tests
​

…and many more
Vibration monitoring is one of the most important mechanical protection systems for rotating machinery. Like any protective device, it must be checked periodically to ensure proper functioning. It is generally recommended to repeat these functional checks every 3–5 years.
This guarantees reliable machine protection in the event of an incident and demonstrates compliance with maintenance obligations.
During a functional check of vibration monitoring systems, the entire signal chain is tested – from the probe to the machine trip function. On the one hand, the probes are verified for correct detection of vibrations (using a shaker simulator for both relative and absolute probes). On the other hand, the active measuring range is checked (linear range verification
with a micrometer).
Furthermore, the processing of vibration data is reviewed against the system configuration (programming). For this purpose, the machine must be at a standstill. If necessary, and in consultation with the customer, repairs, corrections, and readjustments can be carried out
immediately.
Periodic function controls of protection systems
Revisions of turbines and generators always involve significant time and cost. To ensure that everything runs as desired in the field of machine vibrations, Vibro-Consult AG provides dedicated support during the overhaul:
(Hot-) Commissioning of turbines

A basic VC measurement is performed BEFORE the revision. This serves both as a reference for the permissible vibration values after the overhaul and as valuable input for defining the scope of revision work.
During commissioning, Vibro-Consult is on site to monitor machine behavior. In case of irregularities, immediate support is guaranteed and corrective measures can be implemented without delay.
AFTER the overhaul, a basic VC measurement is carried out again, providing documented
proof of the improved vibration quality.
