<p>Pressure transducer (102) is disclosed that includes a housing (110) defining a fluid cavity and a sensor cavity and having an isolation barrier (142, 152) to isolate the fluid cavity from the sensor cavity (126). The pressure transducer further includes a pressure sensor (136) disposed within the sensor cavity (126). The pressure sensor (136) includes at least one pressure inlet. The pressure transducer also includes a capillary tube (148, 158) extending from the at least one pressure inlet to the fluid cavity (144,1 54) through the isolation barrier. The capillary tube includes a lumen (146, 156) having a non-cylindrical shape, preventing flames from passing through the tube.</p> |
