For example, if the pressure at point A is 100 psi and the pressure at point B is 30 psi, the differential pressure is 70 psi. It is crucial for monitoring pressure flow and levels to prevent leaks.  ### What is a Differential Pressure Transducer? ---  A differential pressure transducer is a device that measures the difference between the pressure at two points in a system. This is made possible when an absolute sensor reads the static -- also known as reference -- pressure while the gauge sensor reads the difference between the static and a measured, secondary source.  ### How Does a Differential Pressure Transducer Work? ---  A differential pressure transducer is similar to a gauge transducer. Where a gauge transducer uses atmospheric pressure as a reference, a differential transducer has a secondary input where you can vary the reference. The output of the transducer is the difference between the primary line of pressure and the secondary reference pressure.  --- ### ![IndustryExample_Aerospace](https://info.mensor.com/hs-fs/hubfs/IndustryExample_Aerospace.jpg?width=1200&height=800&name=IndustryExample_Aerospace.jpg) ### Aerospace Differential pressure is used across the the aerospace industry in various applications such as wind tunnels, air data test systems for pitot-static systems, engine characterization and testing, manufacturing processes and flight sensor calibration.   ### ![IndustryExample_Oceanography](https://info.mensor.com/hs-fs/hubfs/IndustryExample_Oceanography.jpg?width=1200&height=800&name=IndustryExample_Oceanography.jpg) ### Oceanography Differential pressure is used to monitor wave propagations and in seafloor seismometer systems. Accurate readings are valuable in modelling/predicting ocean activity.  ### ![IndustryExample_Calibrationlabs](https://info.mensor.com/hs-fs/hubfs/IndustryExample_Calibrationlabs.jpg?width=1202&height=800&name=IndustryExample_Calibrationlabs.jpg) ### Calibration Labs Differential pressure is used across a wide variety of markets, with varying accuracy requirements, leading to a large market of transducers to fit various needs. For these differential pressure sensors, calibration or verification can ensure that these sensors meet their specifications. ### ![IndustryExample_flowlevel](https://info.mensor.com/hs-fs/hubfs/IndustryExample_flowlevel.jpg?width=1200&height=800&name=IndustryExample_flowlevel.jpg) ### Flow Measurement Differential pressure can be used to measure flow across a barrier, like a filter or orifice. This is often used in more industrial settings, where measuring flow rates is used for process control and efficiency.  ### ![IndustryExample_level](https://info.mensor.com/hs-fs/hubfs/IndustryExample_level.jpg?width=1200&height=800&name=IndustryExample_level.jpg) ### Level Measurement Differential pressure can be used to measure the level of fluid in a tank by comparing the pressure of the top and bottom of the tank. Critical measurements might be needed where costly materials are stored or transferred.  --- ![CPT8900-glamour03](https://info.mensor.com/hs-fs/hubfs/CPT8900-glamour03.jpg?width=1800&height=1800&name=CPT8900-glamour03.jpg "CPT8900-glamour03") ## CPT8900 #### High Accuracy Differential Transducer CPT8900 High Accuracy Differential Transducer is the best class of accuracy existing in the market today! - Common mode correction to adjust for static line effects to maximize differential accuracy.  - The perfect accuracy range for applications in the aerospace, flow measurement and calibration labs. - Ideal for OEM instruments that require a high accuracy pressure transducer.
