It's not clear from your question if you have a system you want to demonstrate, or if you want someone else to demonstrate their system. If it is the latter, then I suggest you contact one of NI's alliance members (www.ni.com/alliance).
Mark, Point well taken! My company has a system for measuring driveline torque. It is called MONITORQ. Who would I contact in Austin for aproduct demo: about a 10 minute event. It could be described as a low level sensor gathering input for a plc etc Thanks
You should get in touch with your local Field Sales Engineer. Go to ni.com/niglobal for a listing of worldwide local NI contacts. The Field Sales Engineer can either demo the system for you or put you in touch with the right person in your area.
