Wide Line Pressure Margin and Highly Accurate
PD-A series pressure transducers can measure slight differential pressures highly accurately. They are suitable for long-term measurements and measurements requiring high accuracy. Furthermore, they can be used for not only differential pressure measurement but also indication and control of automation systems based on characteristics of differential pressure sensor like flow rate measurement.| Model | Rated Capacity | Natural Frequency(Approx.) |
