    For differential pressure transmitters measuring the pressure drop across a primary element, the flow rate is directly proportional to the square root of the differential or pressure drop. The ST 3000 transmitter’s output is automatically converted to equal percent of flow when its output conformity is configured as square root.

  • Page 75: Figure 26 Square Root Dropout Point

    70% • 16 + 4 = 15.2 mA dc Output Square root dropout To avoid unstable output at readings near zero, the ST 3000 transmitter automatically drops square root conformity and changes to linear conformity for low differential pressure readings. As shown in Figure 26, the point is near 0.5% of input for ST 3000 transmitters.

    Preventive Maintenance Maintenance routines and schedules The ST 3000 transmitter itself does not require any specific maintenance routine at regularly scheduled intervals. However, you should consider carrying out these typical inspection and maintenance routines on a schedule that is dictated by the characteristics of the process medium being measured and whether blow- down facilities or purge systems are being used.

    Overview About calibration The ST 3000 Smart Transmitter does not require recalibration at periodic intervals to maintain accuracy. If a recalibration is required, we recommend that you do a bench calibration with the transmitter removed from the process and located in a controlled environment to get the best accuracy.

  • Page 125: Resetting Calibration

    Resetting Calibration Background Every ST 3000 transmitter is factory-characterized. The characterization process calculates a mathematical model of the performance of the transmitter’s sensors and stores that data in the transmitter’s memory. Small residual errors result from the sensor data acquisition and modeling process. These errors can be eliminated through calibration, using either a zero offset or a span correction.
