Product Overview
The AERA FC-D985c is a high-precision digital mass flow controller (MFC) engineered for accurate measurement and closed-loop regulation of process gas flows in semiconductor, thin-film, and advanced industrial vacuum systems. Manufactured by AERA Corporation, a recognized brand in precision gas delivery instrumentation, the FC-D985c operates on a thermal mass flow sensing principle combined with an integrated piezoelectric or solenoid-actuated control valve, delivering fast, repeatable flow control independent of upstream pressure and temperature fluctuations. As a core component within automated process control architectures, it interfaces directly with PLC, SCADA, and tool-level host controllers to maintain setpoint accuracy across demanding, continuous-duty manufacturing environments.
