Device for the remote control of pneumatically operated mechanisms, which has fast, high resolution response over a broad range of pressures and which is insensitive to position or vibration

摘要

An electropneumatic transducer which operates quickly and accurately over a broad range of pressures to control high pressure, high flow devices at their point of operation. The transducer is lightweight and insensitive to position or vibration, and can be readily mounted to the device to be controlled at its workpoint and operated remotely by a process controller or other electrical device. There is also provided both internal and external feedback whereby the repeated accurate operation of the transducer is assured.
