Differential Pressure Sensor Frequently Asked Questions

The PDT2 generally outperforms a Magnehelic gauge in accuracy, long term stability, and readability. It offers digital precision with accuracies around ±1 Pa, fast response, and extremely low drift, making it more reliable for continuous HVAC or cleanroom monitoring over time. A Magnehelic gauge is simple and durable but relies on manual visual readings, provides lower precision, and cannot maintain the same long term measurement stability or remote read visibility as the PDT2 s wireless, high resolution digital output.
