Description
Baumer AFF is a rugged, SS316‐wetted, glycerin-filled pressure gauge designed for vibration-heavy, corrosive, and industrial fluid environments. High repeatability, anti-pulsation damping, and wide pressure span make it ideal for chemical dosing, hydraulic skids, boiler lines, compressed air, and aggressive process fluids requiring long-life stability.
