QPress – QHY-HYGIENIC 6600 Series
The QHY-HYGIENIC 6600 Series is a monosilicon hygienic pressure transmitter for sanitary food, beverage and process lines. A flush, cavity-free construction with a 1-1/2 inch tri-clamp connection cleans down with the line, and the monosilicon sensor reads to 30 bar at ±0.2 % of reading with a 4–20 mA and HART output. It gives a dependable, easily cleaned reading on hygienic equipment where product cannot be trapped at the process face. Choose the 6600 for standard 1-1/2 in tri-clamp points; the QHY-HYGIENIC 6200 covers a wider set of hygienic fitting standards.
