The LMS SCADAS III mainframe accepts up to 11 different module types, including any combination of input/output cards, tacho inputs and a variety of signal conditioning modules. The integrated signal conditioning and direct connection of each transducer to the inputs eliminates interconnection problems associated with multiple units or breakout boxes, such as hum, noise, and ground loops.
The entire measurement chain is continuously monitored during testing for open or short circuits. Overload checks are carried out on several places in the signal paths, including full bandwidth checking upfront of the anti-alias filters.
Finally, calibration is on a module-by-module basis and is an entirely digital process. This ensures high quality data over an extended period, or when cards are swapped over.
