Abstract: A sensor body for a flow through pressure sensor includes a strain gage surface to receive a strain gage. The strain gage surface has a curved section and a length extending along a portion of a length of the sensor body. A bore wall thickness is defined as a radial distance between the bore and an outer surface of the sensor body, including the strain gage surface. The curved section can have a substantially greater bore wall thickness over its area relative to the planar surface because a greater responsive surface area for strain measurement is available. Thus a larger strain gage may be used and pressure measurement accuracy increased.

Abstract: A sensor body for a flow through pressure sensor includes a strain gage surface to receive a strain gage. The strain gage surface has a curved section and a length extending along a portion of a length of the sensor body. A bore wall thickness is defined as a radial distance between the bore and an outer surface of the sensor body, including the strain gage surface. In comparison to other sensor bodies in which the strain gage surface is entirely planar, the curved section can have a substantially greater bore wall thickness over its area in comparison to the planar surface because a greater responsive surface area for strain measurement is available. Thus a larger strain gage may be used and pressure measurement accuracy increased. Other advantages include a wider range of pressure that can be measured with a single pressure sensor, and increased component reliability and lifetime.
