3 .2 Principle of operation
VEGAPULS 63 is a radar sensor in K-band technology (emitting
frequency approx. 26 GHz) for continuous level measurement. It is
particularly suitable for small vessels that contain aggressive liquids
under easy process conditions.
The electronics version "Increased sensitivity" enables the use of
VEGAPULS
63 also in applications with very poor reflective properties
or products with low e
r
value.
The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reflected by the product
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an
appropriate output signal and outputted as measured value.
Power is supplied via the H1 Fieldbus. A two-wire cable according to
Fieldbus specification serves as carrier of both power and digital data
for multiple sensors. This cable can be operated in two versions:
l via an H1 interface card in the control system and additional power
supply
l via a Linking device with HSE (High speed Ethernet) and
additional power supply according to IEC 61158-2
