6 December 2006 -- Vega have introduced enhanced electronics versions of their standard radar level transmitters by utilising components from their high dynamic range solids level device. This is especially useful for really challenging liquids applications with ultra low reflectivity and for more difficult foaming, agitated processes. To measure solids level reliably, major technological advances have been achieved in signal processing to handle the weak return signals from low reflectivity products (e.g plastics), uneven product surfaces and heavy dust, both of which can scatter and attenuate return signals.
This is achieved with enhancements to the electronics design.
The solids radar was 1000 times more sensitive than standard radar when it came to the market.
Now some of these benefits have been passed on to the standard liquids radar ensuring even more reliable measurement.
But what does increased 'dynamic range' really mean?
It is the ability of the device to receive and differentiate the smallest echoes from background noise, the equivalent of literally being able to distinguish a 'pin drop from the roar of a football crowd': this is important for applications with weak level reflections.
As a result of these developments, the full range of market leading Vegapuls process radar transmitters has been enhanced with increases in dynamic range.
However, power is nothing without control, the unique Vega 'Echofox' software ensures that the correct echo is identified, chosen and tracked securely.
The result: Vega 2-wire loop powered radar devices are now available with measurement ranges up to 70m, SIL conformance and ATEX approvals.
