Press Release Summary:
Available with ranges up to 70 m, 2-wire loop powered radar devices utilize components with high dynamic range to meet needs of liquids applications with ultra low-reflectivity as well as difficult foaming and agitated processes. ECHOFOX software ensures correct echo is chosen and tracked securely, enabling products to handle weak return signals from low-reflectivity products such as plastics, uneven product surfaces, and heavy dust.
Original Press Release:
VEGAPULS Radar Gets 'Dynamic'
VEGA have introduced enhanced electronics versions to their standard radar level transmitters by utilising components of the 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', 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, VEGA's unique 'ECHOFOX' software ensures the correct echo is chosen and tracked securely. 2-wire loop powered radar devices are now available with ranges up to 70m, SIL conformance and ATEX approvals.
