Pressurized gas to electrical energy conversion for low-power field devices

摘要

An industrial process field device with improved power generation is provided. The process device can be a process variable transmitter, process actuator, or any other suitable field device. The field device includes a wireless transceiver that transceives information related to the process via a wireless medium. A power supply within the field device is couplable to a source of pressurized gas and generates motion within the power supply that is translated into electrical energy. This electrical energy is then used to operate the field device.
