ABSTRACT:
A pressure transducer for clean environments is disclosed. The pressure transducer includes a process coupler, a sensor module, a shield and electronics. The process coupler is configured to couple to a source of process media at a process inlet. The sensor module is coupled to the process coupler and has a pressure sensor therein. The pressure sensor has an electrical characteristic that varies in response to pressure within the sensor module. The shield is disposed adjacent to the process coupler and configured to obstruct substantially all lines of sight between the process inlet and the pressure sensor. Electronics within the transducer are coupled to the pressure sensor to measure the electrical characteristic and provide an indication thereof. A method of sensing a pressure in a clean environment is also provided.
