The VorTek incorporates a unique, modular design concept. This enables you to order only the functions that are required for a specific application, thereby eliminating the need to pay for features that are not required. Instead of multiple electronics platforms for different applications or “series” of models, the VorTek simplifies user selection by utilizing a single electronics platform that can be used from a base of one sensing point up to sixteen sensing points. Any unit can be easily changed in the field to add sensors or reconfigure the range using the free Accutrol Insight graphical software.
