Manufacturer: Azbil Corporation
Model: KFDB

Feature

Model KFDB indicates and controls process variables by converting a change in the differential pressure into mechanical displacement of a torque tube or a torque arm.
A wide variety of measuring elements and control mechanisms to meet various application needs
A pneumatic circuit board and sturdy heat-resistant and weather-proof case greatly improve durability and reliability
The pneumatic circuit board system allows the user to readily add or eliminate control mechanisms and units for flexible modification of functions.

Summary

These units consist of a process variable measurement unit and an indicating controller unit. They measure and adjust temperature, pressure, flow, level, and pneumatic signals. The series offers a cost-effective lineup of controllers and transmitters designed for diverse functional requirements.
High Reliability: Features a pneumatic circuit board (replacing traditional piping), twin bellows for stability, and a weather-resistant metal case.
Vibration Resistance: Pressure elements include balance weights to suppress indicator oscillation and a design that prevents central shaft eccentricity.
Pulsation Countermeasures: Clog-free spiral elements with built-in damping resist process fluctuations.
Parts Standardization: Uses the same measuring elements as existing pneumatic transmitters. This modularity drastically reduces spare parts inventory while enhancing maintainability and economy.
