About this task

To verify that the transducer is working properly, complete the following steps.

Procedure

  1. With the transducer in place and the controlled system pressure stabilized, measure the pressure at the transducer with an accurate and reliable gauge. This is the measured pressure (P).
  2. Determine the maximum (Pmax) and minimum (Pmin) pressure values for the transducer’s pressure range. (See Table 4.)
  3. Use the equation in Figure 1 to determine the calculated output voltage for the 0 VDC to 10 VDC transducers.
    Figure 1. Voltage calculation for 0 VDC to 10 VDC transducers

  4. Measure the voltage between the transducer Output (white) wire and Common (black) wire with a multimeter set to measure DC voltage. (See Figure 1.) This is the measured output voltage.
  5. Compare the calculated output voltage (Step 3) and the measured output voltage (Step 4). If the measured output voltage differs greatly from the calculated output voltage, replace the transducer.
    Note: It is normal for the transducer reading to differ somewhat from pressure gauge readings due to voltmeter and gauge tolerances, and other factors.
