Differential pressure measurement method for e.g. hydraulic system, involves computing corrected pressures based on pressure measured values and temperatures, and forming differential pressure as difference between pressures

摘要

The method involves determining pressure measured values (P1, P2) by pressure sensors (1, 2). A differential pressure (Pdiff) is computed based on the measured values. Temperatures (T1, T2) in environments of the pressure sensors are measured. Corrected pressures (P1korr, P2korr) are computed based on the respective pressure measured values and the temperatures. The differential pressure is formed as a difference between the corrected pressures. An independent claim is also included for a measuring arrangement for differential pressure measurement comprising a pressure sensor.
