FFI SYSTEM OPTICAL-PNEUMATIC POSITIONER DATA SHEET This instrument converts the optical signal from a master station or the like into a pneumatic signal (0.2 to 1.0 kgf/cm 2, etc.) in order to drive a diaphragm type control valve. The operating position of the valve is fed back via link to this positioner to enable accurate positioning. A built-in microcomputer provides intelligent digital processing of signals with a high precision, and the use of a piezoelectric element flapper makes for a low power consumption. This articles are φ6mm optical fiber cable connection type.
