2.1 Function and configuration
Function
The VEGASON … sensor systems or compact instruments are used for continuous and non-contact level measurement.
Short sound impulse packets are emitted by the transducer of the pulse-echo sensor. The combined emitter and receiver system detects the pulses reflected by the product.
The running period of the ultrasonic pulses is directly pro­portional to the distance between sensor and measured product.
The signal processing ECHOFOX of signal analysis to process the reflected ultrasonic pulses.
®
uses modern methods
The signal-to noise ratio is optimized by digital signal processing methods with mathematic algorithms (DSP).
The automatic configuration of a user specific data base enables an optimum adaption to the respective application.
The use of fuzzy-logic for echo evaluation ensures a reliable determination of the level. False echoes, e.g. from stirrers or other installations are detected and are not included in the generation of the measured value.
These measuring data are transmitted digitally to respective signal conditioning instruments or processing systems and processed.
The operation of the sensors is made via the signal conditioning instrument VEGAMET or via a PC (VEGACONNECT necessary).
Compact instruments are additionally equipped with an integral output of the measuring data and make a current output 0 … 20 mA available.
The operation of the compact instrument is only possible with PC via VEGACONNECT.
Configuration
Flange version
The sensor or compact instruments consist of a housing, integrated therein the above electronics and all required terminals, a mounting flange and a transducer.
Housing, flange and transducer are designed acc. to the type.

2.3 Configuration of a measuring system, sensor in not-Ex-area
Generally a measuring system consists of two components
- a local sensor and
- a signal conditioning instrument or processing system
The kind of signal conditioning instrument or processing system depends on the installation conditions.
Sensor(s) VEGASON 83 … 87
Signal conditioning instrument e.g. VEGAMET 514 V (VEGAMET 407 V)
Processing system VEGALOG 571
VEGACONNECT
RS 232
PC
EV -input card (via additionally EV-input cards max. 3 x 5 = 15 sensors each can be connected)
CPU-central unit
Sensor(s) and signal conditioning instrument or processing system are connected via a two-wire line. The power supply of the sensor or the sensors is ensured via this line and the measuring data are transmitted digitally to the signal conditioning instrument or processing system.
The indicating and operating surface VEGA Visual Operating, installed on a PC ensures a simple and comfortable configuration and parameter adjustment of the respective measuring system.
VEGACONNECT can be connected to respective sockets of the signal conditioning instrument or the sensor. If neces­sary, it is possible to connect VEGACONNECT directly to the two-wire line (signal conditioning instrument … sensor).
