The VAF Instruments 3504 is a high-performance process controller, manufactured by Eurotherm in the UK, specifically engineered for precise viscosity monitoring and control in centistokes (cSt). This model is calibrated for a measurement range of 0–50 cSt with a 4–20 mA input signal. It features advanced PID control logic, configurable alarm functions, and a user-friendly interface with manual/auto mode switching, programming, and run/hold capabilities. Designed for industrial and marine applications, it ensures stable and accurate control of fluid viscosity, making it ideal for fuel oil systems and lubrication processes where consistent viscosity is critical for operational efficiency and equipment protection.
