The device converts a current milli-ampere control signal to an equivalent pneumatic signal.
|
| |
Pneumatic
|
|
The device receives a pneumatic control signal and provides a pneumatic signal to the actuator.
|
| |
Digital
|
|
Also known as a "Smart" Positioner. A device that uses a microprocessor to position the pneumatic actuator and to monitor and record data.
|
| |
Electronic
|
|
The device receives an electrical control signal and provides an electrical signal to the actuator.
