ACE Stoßdämpfer GmbH expands its range of useful apps for vibration measurement. VibroChecker PRO is the name of the latest software for the iOS operating system, which simply, quickly and professionally turns an iPhone or iPad into a device for measuring vibrations and impacts.
The innovation is a further development on the very successful VibroChecker app, which has served thousands of users as a mobile vibration measurement device since its introduction in 2014 and, in the same year, was chosen as prize winner of the “automation app awards 2014” in the “Engineering-App” category by readers of the Elektrotechnik trade magazine.
Whilst vibrations can be quickly and simply measured on machines and components within a frequency range of up to 50 Hz with the free VibroChecker, the new VibroChecker PRO app expands the range up to 8000 Hz. This is made possible by simply connecting an external sensor with the iPhone or iPad via the lightning or USB interface and activating it with the app. In comparison with the regular, heavier measurement systems used up until now, this new combination provides users with very high-performance and cost-effective measurement equipment with a total weight of less than 1 kg. In the range up to 50 Hz, both the VibroChecker and the VibroChecker PRO optionally use the acceleration sensors, gyroscopes and microphones integrated in the iPhone and iPad. In the ranges above this level, the connection between the VibroChecker PRO and the external USB sensor Digiducer 333D01 (www.digiducer.com), not included in the nominal fee for the app of 23 Euros, respectively 23 U.S. dollars, ensures even more professional measurements of up to 8000 Hz.
ACE is expanding its service expertise even further with this solution and is providing its own technical staff as well as ACE’s sale partner experts with a professional tool for the measurement of vibrations and impacts with the VibroChecker PRO. After completing the measurement, the results can be saved or simply sent to your own desktop, own specialist department or to the customer by e-mail. This new app is available straight away in the iTunes store for the above-mentioned fee, which is charged for the further development of updates, by following the link:

Vibration plays an important role in manufacturing facilities with rotating machinery processes such as steel and paper formation, power generation and a variety of manufacturing processes employing high-speed cutting and milling. In order to obtain maximum material removal (efficiency), along with good surface quality, the feed and speed of the cutting has to be optimized. In high speed milling, this is directly affected by a number of factors including the sharpness of the cutting bit, the depth of the cut, and the rate of traverse of the cut.
Vibration monitoring can be a key to safeguarding performance, reliability and quality. For example, to monitor tool wear, the vibration signature of a sharpened tool is different from a dull tool. The ability to measure the difference between the two can alert to the need to replace the instrument. This, in turn, can lead to increased productivity and quality by ensuring maximum feed rates with adequate and quality material removal.
A second key to safeguarding quality is the capability from the vibration signature monitoring to distinguish cutting bit and part interaction leading to chatter. Attempting to remove too much material in a single pass or traverse too quickly during the cut can induce a dynamic effect, which causes the cutting bit to chatter or “bounce” which leaves and irregular scoring in the surface finish of the cut part. Chatter can lead to rejected or degraded surface finish quality along with degradation of tool life and reduced throughput.

[In the industrial environment, cables are often routed in cable trays or bundled along with existing cable harnesses necessitating the need for a longer length of sensor signal cable. Rarely can cable be run direct point to point along the floor due to both the trip hazard and likely damage to cable. A cable stretched taut across the facility presents a very real problem.] When it comes to the Digiducer’s USB Accelerometer, folks are less worried about tripping and more concerned about signal integrity that transmits the data through the cable. How long can the USB cable be extended without compromising the integrity of the data measurements?
The Model 333D01 provides a nominal 3 m (10 ft.) integrated USB cable. The matter of how far this cable can be extended without losing signal quality depends on the type of cabling extension used. Passive extenders, such as a wire extender, can transmit up to 4.6 m (15 ft.). This makes it possible to extend the Digiducer’s integrated cable up to an additional 1.8 m (6 ft.) before requiring an active extender. Active electrical extenders can be lengthened up to 9.1 m (30 ft.) coupled with the integrated cable. A USB to Ethernet cable allows for further extension. A single mode fiber optic cable will allow the signal to be carried up to 30 km (18.6 mi.)!
No matter the circumstance, if a longer cable is needed, length can be attained.
