Coronavirus's Impact On Electropneumatic Positioner Companies in Asia Pacific
Electropneumatic Positioners: Introduction Electropneumatic positioners are devices used in control valves with pneumatically operated actuators. These valves are operated by means of electric controllers or control systems. Electropneumatic positioners convert the control signal into a pneumatic output in proportion to lift of the control valve. Electropneumatic positioners are the conventional pneumatic positioners that have an additional integrated electropneumatic transducer. The transducer receives the DC analogue input signal from the control system and converts it into a proportional pneumatic signal, which is then sent to the conventional positioner. Certain pneumatic positioners available in the marketplace have the option of adding an integrated electropneumatic transducer. This option provides customers with a facility to upgrade their existing control technology, while continuing to use their current reliable positioner technology with which they are comfortable and ...
