Abstract: A pressure sensor includes an electrically insulating material covering wires for transmitting an electrical signal generated by a semiconductor pressure-sensing unit, the joints between the wires and the pressure-sensing unit, and the joints between the wires and leads connected to the wires for leading the electrical signal to the outside of the body casing of the sensor. Thus, detection of pressure is possible even in an intense-vibration environment, and it is also possible to reduce influences by changes in temperature.

Abstract: A pressure sensor comprising a hollow main body (11) defining a bore (14) extending therethrough and having a detection end and an output end. A pressure sensing assembly is disposed within said bore (14) to divide it into a detection cavity (17) and an output cavity (18) through which output signal lines from said pressure sensing assembly extend. A flexible diaphragm (19) is attached to the detection end of the bore to define a sealed detection cavity (17) in which a pressure transmitting liquid is filled. The pressure sensing assembly comprises support plate (24) welded to said main body (11) and supporting a pressure sensing element (26) within said detection cavity (17) through a mounting bed (4). The signal lines sealingly extend through said support plate (24) from said detection cavity (17) to said output cavity (18).
