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.

TRANSMITTER, UL/c-UL LISTED
(STANDARD & LOW SPAN
VERSIONS ONLY)
Robertshaw's patented Pulse Frequency Modulated
(PFM) transmitter technology provides digital
transmission up to 1 mile using economical standard
twisted pair wire. This eliminates the cost of more
expensive coaxial or triaxial cable and provides
no-loss accuracy eliminating errors typically found
with analog transmission. Built in field selectable
input linearization allows open channel flow
measurement and level control with volume
conversions for non-cylindrical or horizontal
cylindrical vessels. Setup is simple - just select from
the menu. This eliminates programming at the
factory, entering of time consuming strapping tables,
and allows the user flexibility to use the same
controller if his application changes.
Simple menu prompts guide you step-by-step through
all Setup and Calibration. No technical knowledge is
required. Entry is by built-in keypad
Everything can be done with direct keypad entry.
Calibration can also be accomplished without
completely emptying or filling the vessel. This feature
is in-valuable where tanks are emptied and filled only
once or twice a year during shutdown. All Setup and
Calibration entries can be password protected with a
selection of three distinct levels of access. Calibration
also offers selection of Engineering Units, type of
variable(s) to be displayed, measurement of level and
/or volume or flow, etc. Non-volatile memory insures
setup and calibration data is retained if electrical
power is lost. No battery backup is required.
Displays are abundant to keep you informed of setup
parameters selected, calibration data, setpoint, process
variable, alarm status, error codes, etc. In all there are
two (2) five digits LED displays ( one green and one
red), typically used to display the measured variable
and control setpoint; one 2 line by 20 character
alpha-numeric vacuum fluorescent display (visible in
any type of lighting) for menu prompts during
setup/calibration and configurable as to the data
displayed during normal operation; eight (8) LED
controller status indicators and eight (8) LED alarm
status indicators. These displays give you a wealth of
information at a glance.
requirements. Power supply requirement is 120/240
VAC that is switch selectable in the field. Output is
isolated 4-20 mA. Adjustable response time to handle
agitated or wavy processes is standard.
Continuous Self-Diagnostics and remote Test/Verify
push-button insure you of constant reliability and
safety. Error codes appear on the vacuum Fluorescent
Display when failures occur. This self-monitoring
feature increases instrument stability and accuracy,
eliminating the need for ongoing manual calibration
checking, reducing downtime, and improving system
performance and quality control. It permits early
detection and identification of sensing problems
before they lead to a major breakdown. The test
feature allows conformance to local and federal
environmental regulations.
A variety of sensing probes are available to suit any
application; high temperature/pressure, sanitary,
flanged, inactive lengths, grounded for non-metal
vessels, rigid, flexible, bare or insulated. Lengths are
available up to 100 feet.
In summary, the EXCALIBUR 7000 packs more
features and benefits into one package than you will
find anywhere. It provides local or remote calibration
capability, greater measurement accuracy/stability,
lower startup costs, reduced maintenance costs,
quality control, and lower design costs. It provides
flexibility of configuration or reconfiguration.
Features and options can easily be added in the field
by simple plug in modules. It provides
self-monitoring/self diagnostic capability. This
transmitter/controller will suit ALL your level
Applications… save time, money, and reduce your
parts inventory. Applications are unlimited!!! These
include level and/or interface control in all storage or
process vessels
containing liquids, granulars or
slurries. This includes the chemical/petrochemical,
petroleum refining, water/wastewater, food and
beverage, electric power, pulp and paper,
pharmaceutical, mining and primary metals industries.
Relay options include two or four SPDT 10 amp relays
with independent selectable differential and time delay
on each. All relays are also field selectable High or
Low Level Fail Safe to suit the customer's particular
safety
