PRINCIPAL OF SERVO MEASUREMENT PRINCIPAL OF SERVO MEASUREMENT Principle of measurement Figure 3-1 Principle of measurement The principle is based on detection of variations in the buoyancy of a displacer. The displacer is suspended from a strong, flexible measuring wire which is stored on a precisely grooved measuring drum. The shaft of the drum is connected to the stepper motor via a magnetic coupling.
Page 21
PRINCIPAL OF SERVO MEASUREMENT Level measurement A level variation of product, in which the displacer is partially immersed, causes a change in buoyancy, which will be detected by the force transducer. The resulting difference between measured and desired value will cause a variation in the position of the stepper motor and consequently raise or lower the position of the displacer until the measured value equals the desired value.
Page 22
PRINCIPAL OF SERVO MEASUREMENT Servo gauges Servo tank gauges (Figure 3-2) are a considerable improvement over the float driven instruments. They were developed during the1950s. In this gauge, the float is replaced by a small displacer, suspended by a strong, flexible measuring wire. Instead of a spring-motor, servo gauges use an electrical servo motor to raise and lower the displacer.
Page 23
PRINCIPAL OF SERVO MEASUREMENT The original servo gauge does not look much like today's modern version. The instruments have evolved into highly reliable mature products, and are gradually replacing mechanical float gauges, cutting down on maintenance and improving on inventory results. Modern intelligent servo gauge shave very few moving parts, resulting in long term reliability and accuracy.

SYSTEM ARCHITECTURE SYSTEM ARCHITECTURE 954 SmartServo FlexLine Architecture The 954 SmartServo FlexLine system is built up from interchangeable hardware modules. These modules consist of uniform printed circuit boards (PCBs), each of them representing a different, unique functionality. Together with the software implemented on these hardware parts, each PCB makes up a FlexConn module.
Page 25
SYSTEM ARCHITECTURE FlexConn Modules One of the main characteristics of the 954 SmartServo FlexLine architecture is its placement flexibility of the FlexConn modules. Any types of modules can be added. Two identical modules can also be placed in the 954 SmartServo FlexLine system. Each FlexConn module has one or more function.
Page 26
SYSTEM ARCHITECTURE Each FlexConn PCB consists of a generic and a specific electronic part. The generic part can be found on any FlexConn modules. The specific electronics part represents an application-specific function. Figure 4-3. Figure 4-3 A typical FlexConn PCB layout The following parts are available on the generic electronics part.

SYSTEM ARCHITECTURE 3 voltage monitors The output of these monitors, being voltage levels from three different FlexConn PCB locations, are used for diagnostics purposes. Figure 4-4 Figure 4-4 Locations of the 3 voltage monitors 1 temperature sensor For the operational PCB, this sensor acts as an input for environmental- temperature diagnostics.
Page 30
SYSTEM ARCHITECTURE Entities Information exchange between the various FlexConn modules takes place by means of the entities. An entity represents a unique information association in the FlexConn architecture. This information may consist of measuring data, status data, commissioning parameters, diagnostics data, or commands. In addition to the information exchange between FlexConn modules, entities are used for data presentation on the HART SmartView display, and for the communication between the Engauge service tool and the...
