KOSO EP1000 Electro-Pneumatic Positioner

KOSO EP1000 Electro-Pneumatic Positioner is an intelligent electropneumatic positioner that conforms to field equipment communication standard HART, which is a world standard. KOSO EP1000 Electro-Pneumatic Positioner 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). KOSO EP1000 Electro-Pneumatic Positioner 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.

Product Features

KOSO EP1000 Electro-Pneumatic Positioner can be mounted to an actuator of any of single action type, double action type, rotary type and linear type, and KOSO EP1000 Electro-Pneumatic Positioner operates with a 4-20mA instrumentation signal and compressed air. KOSO is now developing FF dealing equipment, which digitalizes up to control signals and conforms to Fieldbus Foundation Standards. The outer shell of KOSO EP1000 Electro-Pneumatic Positioner is made of aluminum alloy. KOSO EP1000 Electro-Pneumatic Positioner uses epoxy-based paint. KOSO EP1000 Electro-Pneumatic Positioner is the main accessory of the regulating valve. It is usually used in conjunction with the pneumatic regulating valve. It receives the output signal of the regulator, and then uses its output signal to control the pneumatic regulating valve. When the regulating valve is actuated, the valve stem The displacement is fed back to the valve positioner through the mechanical device, and the valve position status is transmitted to the upper system through electrical signals.
