Key Features Product Description Specifications Downloads

Use and Versatility
An intuitive web interface is available for easy configuration and interaction as well as display of live data graphs and state of health information, using any web browser.
The device configuration file in XML format can be alternatively edited on site through the instrument console, exchanged by replacing the memory card, remotely from a server or through SSH from anywhere in the world.
Modular plug-in electronics structure provides highly increased serviceability and maintenance as well as easy hardware field upgrades or replacements.
Data Analysis
scai slim can perform realtime single/double integration, differentiation, HP/LP/BP filtering, decimation, peak/average calculations on the physical sensor signal and can provide these as realtime virtual signal. All recording and monitoring features can be applied on the virtual signals, simultaneous to the physical signals.
