QPress – QSF-CLAMP 3500 Series
The QSF-CLAMP 3500 Series is a sanitary flush-diaphragm pressure transducer for food, beverage and general process duty. A flush 316L diaphragm leaves no cavity to trap product and cleans down easily, while the IP65 housing handles washdown environments. It reads to 100 bar at ±0.5 % FS with a fast 4–20 mA output and offers a wide range of flush process connections, from M20x1.5 and G1/2 to G1 and M30x1.5, for varied sanitary equipment. Choose the 3500 when sanitary duty runs above 10 bar or spans general process work; the QSF-CLAMP 1300 is the dedicated CIP/SIP pick.
