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.
