Detailed Product Description

This is an intelligent electropneumatic positioner that conforms to field equipment communication standard HART, which is a world standard.

It permits easy and positive digital adjustment of positioner response characteristics and zero and span from a host equipment mounting DDL or from an HHC (Hand Held Communicator). Furthermore, with 3-key calibration executed by a pushbutton built in the positioner, it is possible to set principal items by unit positioner, without need for HHC or the like.

It can be mounted to an actuator of any of single action type, double action type, rotary type and linear type, and it operates with a 4-20mA instrumentation signal and compressed air. Therefore, it is a positioner of broad universality, and it is capable of transmitting self-diagnosis information and others besides valve opening and open/close limit signals to a host equipment that conforms to HART.

KOSO is now developing FF dealing equipment, which digitalizes up to control signals and conforms to Fieldbus Foundation Standards.
