The optically and technically redesigned air and gas velocity sensor excels in accuracy, reliability, and simplified installation. Optimised for demanding industrial applications with a measurement range from 0 to 40 m/s (0 to 8 000ft/min) and temperatures from -40 to +140 °C (-40 °F to 284°F), it is suitable for a wide range of uses – from pharmaceutical production to process monitoring in 3D printing. The optional external pressure sensor compensates for variations in ambient pressure. Thanks to its robust ceramic sensing element protected by a stainless steel probe head and a specialised coating, the AVS701 delivers stable measurement results even under corrosive and extreme conditions, significantly reducing downtime and lifecycle costs. Efficiency increases in process costs and quicker setup times by 60% make the AVS701 the best choice in its performance class.
