Yokogawa YCB146 製品紹介
The Yokogawa YCB146 is a high-precision, robust, and reliable current-to-pressure (I/P) converter designed for industrial automation and process control applications. It converts electrical signals (4–20 mA) into proportional pneumatic output pressure (3–15 psi or 20–100 kPa), ensuring accurate control / pneumatic actuators, valves, and other devices in harsh environments. The YCB146 is widely used in industries such as oil & gas, chemical, power generation, and water treatment due to its durability and exceptional performance.
