2.1Function 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.
Separate version
The separate version consists of a housing with integral
electronics and all necessary terminal and mounting plate.
Transducer with mounting tube and connection cable as
separate modular unit. The transducers differ acc. to the
various types.
