The KF Series of Field Mounted Indicating Controllers, which the special manufacturing techniques is introduced from Japanese Yamatak-Honeywell Co., Ltd, provides both application flexibility and instrumentation savings by employing a common type of indicating control section in each instrument. All process variables, such as temperature, pressure, level and flow, can be measured and controlled by the same type of instrument. The difference is only in the detector. Thus, the KF Series provides model simplicity and uniformity, and requires very little in the way of maintenance. The KF Series comprises not only Indicating Transmitters but also Indicating Transmitting Controllers. They are united in structure, and combined in functions, complete in varieties and specifications with stable performance, high precision, strong anti-interference ability, high reliability, and are easy to mount and maintain. They are intrinsically safe and explosion-proof, able to drive the pneumatic performance mechanism directly, so they have been generally well accepted and trusted by domestic and foreign customers.
