NON-CONTACT VIBRATION MEASUREMENT
Polytec manufactures a wide range of laser vibrometers that are the acknowledged gold-standard for non-contact vibration measurement. No matter your measurement need in research, development and production or even for long-term monitoring, there is a Polytec system to provide the answer. Laser-Doppler vibrometers analyze samples of different size, from entire car bodies, large aerospace parts over engines and actuators to micron-sized MEMS or delicate HDD components.
Numerous other research applications in mechanical and civil engineering, biology and medicine benefit from the superior properties of non-contact Vibrometry. Laser vibrometers easily master challenging conditions like measuring on hot surfaces, on rotating parts, and characterize complex and sensitive structures even in the ultrasonic frequency range. Vibrometers from Polytec help to solve your measurement task fast, reactionless and precise.
NON-CONTACT SPEED AND LENGTH MEASUREMENT
When producing strip material, e.g. in steel or paper mills, knowing exactly the strip length and the current velocity is essential for lowering your costs and optimizing your products and processes. Here, Polytec offers solutions for precise process control. LSV Laser Surface Velocimeters are high-performance non-contact sensors for a reliable measurement of length and speed.
Thanks to the optical measurement the sensor captures length and speed reliably in challenging industrial environments. LSV offer a high level of robustness and process integrity at minimal maintenance cost.
Non-contact surface characterization
In order to characterize precision-manufactured and other sophisticated surfaces, it needs measurement technology that is reliable, quick and application-oriented. Guaranteeing functionality and detecting defects at an early stage avoids unnecessary cost and increases the overall product quality and lifetime.
Polytec addresses surface metrology applications with innovative, high-precision, non-contact optical technology that works on rough, smooth and stepped surfaces. White-light interferometers of the TopMap family are established quality inspection tools for the controls laboratory, in production environments or in-line.
Detecting errors and cutting costs
Mastering machine vision means finding the ideal combination of individual components – and taking interactions and ambient conditions into consideration while doing so.
And to do this, you should place your trust in Polytec – and its more than 40 years of experience as a distributor, manufacturer and service provider of machine vision solutions. This profound experience is also reflected by its practical portfolio. In this regard, you can choose from an extensive range of products that has something to offer for practically every application.
In addition to providing you with instrument-based systems, Polytec also has its very own Service department dedicated to training, support, calibration and repairs. After all, targeted consulting, rental solutions and feasibility studies help to optimally combine components that best suit your tasks at hand.
So, make Polytec your first choice!
Ideal measuring technology solutions
This technology area is by far the most diverse of all of Polytec’s areas of expertise – both with regard to the technology and the products. It ranges from optical, electro-optical and electrical measurement technology for use in the laboratory, field and production, to optical sources across all spectral ranges for an extremely wide range of applications.
And, nevertheless, we are still experts in every single area. Because, for each of the numerous product fields, we have consulting engineers who devote all their energies to that one specific area. These experts and the ideal service technicians have a wealth of experience and detailed knowledge which even some manufacturers are envious of. Place your trust in 50 years of experience and knowledge.
Analyzing ingredients and optimizing processes
Process analytics is used to optimize the production process, to ensure consistent product quality and, last but not least, to meet environmental requirements. The objective in this regard is to improve product quality and enhance efficiency with a view to reducing costs, saving time and cutting emissions. Automated real-time control allows for controlled interventions to be made even during the product manufacturing process. Costly and time-consuming faulty production operations are prevented as a result.
Process analytics can be used throughout the entire production chain: when inspecting incoming goods, during production (either online in the form of automatic sampling while bypassing process control, or inline in the form of automatic sampling directly during process control) and during final product control.
As they are easy to use and robust, spectroscopic methods – particularly near-infrared (NIR) spectroscopy based on dispersive diode array technology – are a popular choice in this area of application.
The available measured variables are diverse in this regard:
- Qualitative and quantitative compositional analyses to determine the concentration of products, additives and by-products, and to identify process-specific substances
- Physical parameters in both the reactor and the reaction mixture, such as the moisture level
- Layer thickness measurement
