Abstract
A downhole pressure transmitter apparatus and method of making the same. A pressure fitting can be provided in association with a tube formed into a spiral shape. One end of said tube is sealed and the other end of said tube is affixed to said pressure fitting. As the tube is exposed to a differential pressure, said tube unwinds, thereby creating a rotary motion that is proportional and linear to said differential pressure sensor, thereby providing an indication of pressure within a downhole environment.
