Abstract
There is disclosed a header for a differential pressure transducer. The header has a cylindrical sensor housing section which has a front and a back surface. The front surface has a sensor accommodating recess. There is a plurality of terminal pins extending from the front surface and directed through the housing to extend from said back surface. The pins are arranged in a semi-circular pattern, said sensor housing having a stem aperture and cylindrical wall. A stem housing is positioned in the stem aperture and is brazed thereto. The stem housing has a stem passageway directed through the housing which communicates with a passageway in the cylindrical sensor housing. The cylindrical sensor recess contains a sensing device which receives a first input pressure on one diaphragm surface of the sensing device and a second input pressure on a second surface of the diaphragm to produce a differential output pressure. The header, as indicated, is rugged and simple to use and produce.
