ABSTRACT:
The disclosure is drawn to a statc pressure unit having a circular dividing fitting with two silicon strain gauges glass bonded thereto. The strain gauges are located to place one strain gauge in tension and one in compression when the fitting is pressurized. One of two embodiments may be employed. In either case, one strain gauge is positioned in tension symmetrically across the center of the fitting. The other strain gauge is placed so that it is in compression.
