DIFFERENTIAL PRESSURE APPARATUS |
摘要 |
A differential pressure unit to induce tension and compression in respective strain gages to produce a change in the output of a Wheatstone bridge. The differential pressure or some function thereof is then indicated. Error due to temperature is avoided by maintaining the bridge current constant. The bridge voltage is elevated as a function of temperature to make the bridge current or bridge output independent of temperature. |
