Frequently asked questions about our products.


What is the difference between MIG16 SFE and a vibration monitor?

MIG16 SFE works just like a vibration monitor and constantly monitors a machine's vibrations, and sounds a pre-alert if the vibrations are too large, in order to protect the machine and its environment.

However, in contrast to a vibration monitor, MIG16 SFE is still able to perform this function reliably even if the operating conditions for the machine are highly dynamic. For example, motor-sport engines with accelerations from 0 to 8,000 rpm in 0.1 seconds can be monitored with individual thresholds for each speed band. Vibration monitors do not offer this function. They are generally designed to monitor machines that run constantly (e.g. permanently at 2,000 rpm).

How can we get to know MIG16 SFE?

We are happy to present the opportunities and the added value as well as reference applications for MIG16 SFE as part of a personal on-site demonstration.

In addition, we offer a budget-friendly way to find out firsthand about MIG16 SFE's excellent performance in your own testing environment: you can rent MIG16 SFE as part of a workshop for the duration of a test run. We support the test run together with you, and show you the simple use and the high information value of the measurement data, indicators, and reports generated by MIG16 SFE.

Can existing test stands be retrofitted with MIG16 AQS?

Yes. The integration effort is even very low for many modern test stands. Please contact us and we will provide you with a non-binding analysis of your application.

How is MIG16 AQS integrated into the test stand?

The MIG16 AQS interface for automated systems was developed to offer our partner firms, test machine builders, and others a superior NVH measurement and analysis platform. It can be easily integrated into the existing machine control unit and includes dynamic sensor data, part series numbers, and tolerance criteria via one of several available interfaces, such as Ethernet, Profibus and/or CAN-bus. The systems record time data while calculations are performed parallel and in real-time at the top level. The resulting amplitudes are compared with threshold values (MIG16 AQS complete NVH solution develops and manages the indicators internally; in the case of MIG16 AQS intelligent sensor, the data are transferred to the connected test stand computers for evaluation and threshold value analysis).

MIG16 AQS can either be integrated with an active user interface via a KVM switch or as a "blind unit" to control the computer that records the data.

Can the quality data from MIG16 AQS be fed into an existing quality database (e.g., ASAM ODS)?

Yes. MIG16 AQS is based on an open relational SQL database (MS SQL server). It is thus possible to link the data with current technology:

  • MIG16 AQS can actively play the data into QS sytems after completing the measurement stages (push function).
  • Data can also be replicated using the database engine.
  • QA systems can independently access the MIG16 AQS data.

How are sensors attached?

Depending on the specific application, vibration sensors are screwed or glued, attached using a magnet or a probe tip to the test item. Each form of attachment has its specific advantages and disadvantages. Just get in touch with us and we will provide you with a non-binding analysis of your application and suggest various means of attachment.

What is structure-borne sound and how is it measured?

Structure-borne sound is the noise which spreads through structures (e.g. in a gear or housing). Structure-borne noise is caused by dynamic forces that are primarily caused in gears by the transferring the force of the gear mesh from the pinion to the spur gear. The effect of the vibration causes noise to be reflected into the air, so-called airborne noise. 
Structure-born sound is technically usable to assess objectively the quality of

  • the gears
  • mesh gear
  • assembly
  • interaction of all of the components

Standards: DIN ISO 10816 | VDI 3832

Structure-borne sound is measured as surface vibration acceleration using an acceleration sensor (vibration sensor). Unit: g or m/s²

What is order analysis?

The order spectrum is a tried and trusted mathematical aid used to separate individual noises from various components and noise sources (e.g. gear, drive, test stand) within the entire noise of a rotating machine (e.g. gears). Order analysis is a key method for vibration analysis. MIG16 includes order analysis with a precision that is not offered by any other competing product.

What does red-ant do?

red-ant has developed a measurement technology product which can be used for applications including quality assurance for gears. One example: in general, at the end of a production line for car gears, each gear is automatically subjected to many tests before it is built into the car. Does it switch properly? Is the transmission correct? Is it easy to use? etc. The red-ant product MIG16 AQS performs one of these tests fully automatically: the so-called "acoustic test".

What is more, red-ant's employees are specialists for sound testing - or to put it in technical terms "vibration analysis".
As a result, red-ant's range of services includes

  • the sale of measurement technology
  • providing services for vibration analysis

What is the lead time/availability?

red-ant has a pool of readily available MIG16 measurement systems. Therefore, it can provide measurement technology without delay for time-critical use requests. Just contact us for non-binding information on what we have in stock. The lead-time when buying new systems is generally 4-6 weeks. If you need a system more quickly, we can cut the lead-time by supplying a measurement system from our rental inventory.

What does the term XY mean?

Despite our aim of keeping all of our publications as easy to understand as possible, even red-ant has to use specialist terminology from the area of measurement technology, vibration analysis, etc. Just read our glossary to find out what these special terms mean.
