Product Overview
The MASONEILAN 8012DEX-3-C is a precision electropneumatic transducer engineered to convert a standard electrical control signal (typically 4–20 mA or 0–10 VDC) into a proportional pneumatic output pressure for actuation of control valves, dampers, and other final control elements. Manufactured by Masoneilan, a globally recognized brand in process control instrumentation, this transducer serves as the critical signal interface between electronic control systems (DCS, PLC, or single-loop controllers) and pneumatically actuated process valves. The 8012DEX-3-C is designed for high-resolution, low-hysteresis signal conversion, ensuring accurate and repeatable positioning of pneumatic actuators in demanding industrial process environments. Its robust construction and stable output characteristics make it a reliable component in closed-loop process control architectures.
