T he type label contains the most important data for identification and
use of the instrument:
l I nstrument type
l A rticle and serial number device
l A rticle numbers, documentation
l T echnical data: Approvals, antenna type, process fitting, process
seal/temperature, signal output, voltage supply, protection, pro-
tection class
l SIL identification (with SIL rating ex works)
W ith the serial number, you can access the delivery data of the
instrument via www.vega.com, "VEGA Tools" and "serial number
search". In addition to the type label outside, you can also find the
serial number on the inside of the instrument.
3 .2 Principle of operation
T he VEGAPULS 67 is particularly suitable for measurement of bulk
solids in silos with up to 15 m height.
T he 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 running 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.
