GENERAL DESCRIPTION
The Robertshaw EXCALIBUR 7000 offers you TWO INSTRUMENTS
FOR THE PRICE OF ONE. Both a SMART RF capacitance microprocessor based
Level Transmitter and PID Controller, this unique instrument provides the
flexibility to meet all your level application requirements. The Excalibur
7000 has built-in PID Control with AUTO TUNE to eliminate offset and
provide accuracy and stability. The auto tune feature eliminates periodic
on-line tuning by automatically matching control action with your
particular process characteristics. This feature alone eliminates many
hours of fine tuning to your particular process and the need for, and the
cost of, a separate controller. Patented optional RF anti-coating
circuitry eliminates errors due to product build-up on the probe assuring
you of accurate level measurements in all types of coating applications.
