Robertshaw Excalibur Level Controller - Multi-Point
Probe is an option



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.

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.

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 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.

n summary, the Robertshaw 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.

Robertshaw 5400 Level-Lance Multi-Point On/Off Level Controller


GENERAL DESCRIPTION
The ROBERTSHAW Level-Lance Model 5400A is a microprocessor based, multi-point On-Off capacitance type level detection system. Utilizing the Pulse Frequency Modulation (PFM) method of signal transmission ensures that accuracy, repeatability and longevity are enhanced over level systems using conventional analog transmission schemes. The PFM transmitter, normally mounted directly on the sensing probe, requires no calibration or adjustments of any kind. The control unit can be mounted up to one mile from the PFM transmitter without requiring any special type of interconnecting wire or cable. Two wires are all that is required. The PFM transmitter does not require any primary power because it receives its operating power from the control unit over the same two wires used to transmit the level signal.

The PFM (Pulse Frequency Modulation) transmitter is also designed to provide electrostatic protection at the probe input. It transmits a frequency modulated pulse signal to the microprocessor based control unit. The variation in the frequency of the pulse is proportional to the product level on the sensing probe. The microprocessor in the control unit receives the pulse and processes it to extract the level information. The microprocessor then compares this level information to the “AUTO-SET” calibration data stored in the non-volatile memory. When the level data coincides with this previously stored data, the appropriate output relay is either activated or deactivated, to give the desired control action. The total system design has been optimized to yield the highest possible levels of both EMI and RFI rejection.

The Model 5400A Level-Lance is calibrated by means of the “AUTO-SET” feature. This feature permits all calibration of the unit to be done by the simple act of pushing a button.

The Model 5400A Level-Lance is designed with plug-in type relay output modules to allow for easy configuration changes. Relay outputs can be added or removed in the field by the user. The control unit has the capability of having up to four relay output modules installed. The PFM input is optically coupled for better noise immunity. 


Each relay output can be individually configured for:
  1. A)  Fixed minimum or adjustable differential (deadband).
  2. B)  High or Low level fail safe.
  3. C)  Adjustable time delay.
These selections are made by means of miniature selector switches located on the individual relay output modules. All relay output module functions are totally independent of other relay output modules.
An additional switch located on the main (microprocessor) board allows for selection of the overall operating mode as follows:
  1. A)  Normal operation.
  2. B)  Load sharing. This mode permits the sequential
    operation of two to four pumps or motors,
    alternated or rotated to prolong their life.
  3. C)  Test (self diagnostics). LED’s indicate transmitter (PFM) or receiver (RCVR) failure or
    calibration (CAL) error.
