The EXCALIBUR 7000 has UP TO 1 MILE WITH STANDARD. built-in PID Control with AUTO TUNE to eliminate TWISTED PAIR CABLE (NO COAX. offset and provide accuracy and stability. The auto tune OR TRIAX NEEDED). feature eliminates periodic on-line tuning by NEMA 4/4X ENCLOSURES. automatically matching control action with your INTRINSICALLY SAFE PFM. particular process characteristics. This feature alone transmitter , UL/c-UL LISTED. eliminates many hours of fine tuning to your particular (STANDARD & LOW SPAN. process and the need for, and the cost of, a separate VERSIONS ONLY). 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.

3 1. Robertshaw 's patented Pulse Frequency Modulated requirements. Power supply requirement is 120/240. (PFM) transmitter technology provides digital VAC that is switch selectable in the field. Output is transmission up to 1 mile using economical standard isolated 4-20 mA. Adjustable response time to handle twisted pair wire. This eliminates the cost of more agitated or wavy processes is standard. expensive coaxial or triaxial cable and provides no-loss accuracy eliminating errors typically found Continuous Self-Diagnostics and remote Test/Verify with analog transmission. Built in field selectable push-button insure you of constant reliability and input linearization allows open channel flow safety. Error codes appear on the vacuum Fluorescent measurement and level control with volume Display when failures occur.

Setup is simple - just select from eliminating the need for ongoing manual calibration the menu. This eliminates programming at the checking, reducing downtime, and improving system factory, entering of time consuming strapping tables, performance and quality control. It permits early and allows the user flexibility to use the same detection and identification of sensing problems controller if his application changes. before they lead to a major breakdown. The test feature allows conformance to local and federal Simple menu prompts guide you step-by-step through environmental regulations. all Setup and Calibration. No technical knowledge is required.

This feature vessels, rigid, flexible, bare or insulated. Lengths are is in-valuable where tanks are emptied and filled only available up to 100 feet. once or twice a year during shutdown. All Setup and Calibration entries can be password protected with a In summary, the EXCALIBUR 7000 packs more selection of three distinct levels of access. Calibration features and benefits into one package than you will also offers selection of Engineering Units, type of find anywhere.

6 It provides local or remote calibration variable(s) to be displayed, measurement of level and capability, greater measurement accuracy/stability, /or volume or flow, etc. Non-volatile memory insures lower startup costs, reduced maintenance costs, setup and calibration data is retained if electrical quality control, and lower design costs. It provides power is lost. No battery backup is required. flexibility of configuration or reconfiguration. Features and options can easily be added in the field Displays are abundant to keep you informed of setup by simple plug in modules. It provides parameters selected, calibration data, setpoint, process self-monitoring/self diagnostic capability. This variable, alarm status, error codes, etc. In all there are transmitter /controller will suit ALL your level two (2) five digits LED displays ( one green and one Applications save time, money, and reduce your red), typically used to display the measured variable parts inventory.
