Model KFK Pressure indicating Controllers (adjustable range type) indicate and control a process variable by converting its pressure into mechanical displacement of a bellows or a spiral pressure receiving element. Indicating transmitters and indicating transmitting controllers also are available as well as indicating controllers. The controllers are available either in the local type to set the set-point value with the knob on the instrument or in the cascade type (remote type) to set the set-point value with a pneumatic signal. **A wide variety of measuring elements and control mechanisms are available to meet various applications. **A pneumatic circuit board and a heat-resistant weatherproof sturdy hard case are used, thereby greatly improving the durability and reliability. **The pneumatic circuit board system allows to readily add or eliminate control mechanisms and units, thereby enhancing the system modification and expansion flexibility. **Interchangeable parts are used to the maximum practicable extent, thereby reducing the number of parts to be kept in stock. **The detecting section is identical with that of the pressure transmitter of PREX3000 Pneumatic Transmitter Series.
