The Portable Pressure Source PPS1100 offers quick, efficient and accurate means for checking pressure transducers in the field. To preform a pressure transducer test, simply remove the transducer from the process and install it in the pressure port on the PPS1100 manifold. Turn the PPS1100 on and select the required engineering unit. Adjust zero and pump the pressure source until the desired pressure appears on the PPS1100 display. Then compare the pressure readout on the PPS1100 to the pressure transducer readout to verify the transducer's accuracy.
