About this task

To verify that the P598 Series transducer is functioning correctly, complete the following steps:

Procedure

  1. Ensure that the transducer is in place and the controlled system pressure is stabilized. Measure the pressure at the transducer with an accurate gauge. The resulting value is the measured pressure (P).
  2. Determine the maximum (Pmax) and minimum (Pmin) pressure values for the transducer’s pressure range. See Table 5 and Table 9 for more information.
  3. Use the following equation to determine the calculated output current for the 4 mA to 20 mA transducers:

    • I = Calculated output current
    • P = Measured pressure
    • Pmax = Max span
    • Pmin = Min span
  4. Measure the transducer output current.
    1. Disconnect the common (-) wire.
    2. Set your multimeter to milliamperes (mA).
    3. Connect the multimeter’s red test-lead to the transducer output common (-) PIN wire and the multimeter’s black test-lead to the common (-) wire.

      The milliamperes (mA) reading on your multimeter is the measured output current. See Table 2 for the pin out configuration.

  5. Compare the output current calculated in Step 3 to the output current measured in Step 4. If the current from the measured output current differs greatly from the calculated output current, replace the transducer.
    Note: Under normal conditions, the transducer reading differs somewhat from pressure meter readings due to multimeter and pressure meter tolerances.
