FISHER 646 pneumatic converter

The FISHER Type 646 is an electric-pneumatic converter designed to convert a current signal of 4-20mA into a proportional pneumatic pressure output. This device is essential for the precise control of processes where electrical signals from measurement technology or controls need to be translated into pneumatic control commands for valves or other actuators. With a typical current interface of 4-20mA, the 646 converter provides a reliable interface between the electrical control world and pneumatic actuation. Its design is focused on robustness and durability to meet the demands of industrial environments. Application areas include process automation, the chemical industry, oil and gas production, and power plants, where precise control valve positioning or pressure regulation is required. Order it as a spare part or for new installations.
