Masoneilan SVI II AP is an advanced digital positioner leveraging a 32-bit microprocessor for precise pneumatic actuator control via 4-20 mA HART signals. Its non-contact Hall-effect position sensor ensures high resolution (0.0015%) and SIL 2 compliance, while the high-flow option (Cv 2.2) supports large actuators without boosters. Designed for retrofit on single/double-acting valves, it features robust electronics and field-upgradable firmware for long-term adaptability in demanding industrial settings.
