Factors that Affect Accuracy DEA BRAVO HP: Environment Temperature Environment temperature variation is one of the factors affecting the metrologic performance of measurement equipment. To limit unwanted effects, the most common solution consists in simulating the ideal temperature conditions in enclosures or rooms. This solution is the simplest on a technical basis, but it is the most expensive one, particularly for large-sized measuring machines. In most cases, the DEA BRAVO HP series requires no air-conditioned machine enclosure since it is designed to work efficiently in a shop-floor environment. The technological solutions adopted are the outcome of many years of experience in the application of measurement systems in industrial environments.

The foundation on which the measuring machine is installed plays two significant roles: it stabilizes the geometric rigidity of dual-arm systems and it insulates vibrations. Depending on the nature (frequency and intensity) of vibrations, further insulating elements may be added to the foundation - both passive, and, in the most critical cases, active elements. In all cases, the rigidity of the X beam of the DEA BRAVO HP systems helps ensure that the initial performance is kept over time. Peak-to-Peak Acceleration (mm/s²)
