Pressure Calibration Sample Clauses

Pressure Calibration. 2.3.1 Once the ▇▇▇▇▇▇ is reassembled a recalibration of the pressure sensor is done. The ▇▇▇▇▇▇ is secured to the test equipment and the ambient pressure is logged. Measurements of the pressure sensor’s output are polled and recorded at known levels of head pressure. These are then plotted and compared to what the head pressure and the atmospheric pressure are exerting and a linear relationship is plotted. From this linear plot an offset and gain value are recorded to be written to the ▇▇▇▇▇▇ software package. Once the ▇▇▇▇▇▇ is reassembled a recalibration of the pressure sensor is done. The ▇▇▇▇▇▇ is secured to the test equipment and the ambient pressure is logged. A test cylinder is filled with water and the control board polls both ▇▇▇▇▇▇’▇ pressure gauge output and the NIST pressure gauge. The two values are recorded and the cylinder is gradually drained of water while the two gauges continue to record measurements. The two data sets are then plotted and a linear relationship is found between them. This provides gain and offset coefficients for pressure which are recorded and then written to the ▇▇▇▇▇▇.
