The differential pressure gauges of the PCE-PDA series are reliable differential pressure gauges for pressure measurement of gasses in the range of ± 200 Pa, ± 2kPa and 20 kPa depending on the model. The differential pressure gauge has many different pressure measuring functions. This gives the user more than 16 units. Furthermore, the differential pressure gauge measures in addition to the differential pressure, the temperature, flow velocity and volume flow. In addition, the maximum and minimum differential pressure can be displayed in the two-part graphic display. The resolution of the differential pressure can optionally be switched. The differential pressure gauge incorporates a high-precision mode that increases the resolution tenfold.

The PCE-PDA differential pressure gauge has a data logger function. This makes it possible to carry out a leak test on pressure lines in addition to the continuous storage of the measured values. In the data logger mode, it is possible to set the differential pressure gauge to a duration in which the data is stored at a previously selected interval. In the leakage measurement mode, the user must specify the measurement duration and the differential pressure level. After the measurement, the differential pressure gauge then displays the deviation from the set point. In addition to these two functions, the differential pressure gauge, with optional Pilot tubes, can determine the flow velocity or volume flow in pipes.
