Patent abstract
Methods and apparatus for sensing a gauge pressure use a pressure gauge pressure sensor that includes a housing and a gauge pressure sensing element having a first pressure inlet and a second pressure inlet. The first pressure inlet is associated with a pressure to be measured and the second pressure inlet is associated with an atmospheric pressure. A flame arrestor disposed within the sensor housing fluidly couples the second pressure inlet to an internal portion of an explosion proof device.
