Differential pressure sensors
These pressure sensors (pressure transducers or pressure transmitters) measure the difference in pressure between two points within a system, providing a direct indicator of flow rate, level, or other variables dependent on pressure variance. These sensors are pivotal for applications requiring precise monitoring of pressure gradients, such as in filter condition monitoring, fan and blower pressure, and fluid dynamics in piping systems. By detecting subtle changes in pressure, differential pressure sensors help maintain system efficiency, enhance safety by detecting leaks or blockages, and contribute to energy conservation by optimizing process operations. These sensors are integrated in advanced technologies to deliver reliable and actionable data, critical for automating and refining modern industrial processes.measure the difference in pressure between two points within a system, providing a direct indicator of flow rate, level, or other variables dependent on pressure variance.

Some things to consider selecting the right differential pressure sensor
- Ensure range coverage: Choose a sensor that accurately measures the full pressure differential in your application, with protection against overpressure.
- Prioritize accuracy: Select a sensor with the required accuracy and resolution for precise monitoring, especially in critical applications like flow measurement and filtration.
- Match materials to media: Ensure the sensor's materials are compatible with the fluids or gases it will encounter, particularly if corrosive.
- Environmental suitability: Opt for sensors that can handle the operating environment, including temperature variations and exposure to chemicals, with temperature compensation if needed.
- Choose the right output: Select a sensor with the appropriate analog or digital output that integrates smoothly with your system.
- Installation fit: Ensure the sensor’s size, shape, and mounting options suit your setup for easy integration.
- Consider power needs: For energy-sensitive applications, select sensors with low power consumption.
By considering these key points, you can choose the best differential pressure sensor for reliable, precise performance in your application.

Frequently asked questions about Differential pressure sensors
Answers to the most important technical questions
Are miniature differential pressure sensors available?
Yes. A compact example is the Sensorade mp2.40 differential pressure transducer, which is particularly suitable for measuring differential pressure in air and for aerodynamics applications.
Because a differential pressure sensor requires two pressure connections, it is generally larger than a single miniature pressure sensor. For applications with very limited installation space, it is therefore important to determine whether a compact differential pressure sensor provides sufficient space savings or whether a custom solution using miniature pressure sensors is more appropriate.
Althen can help select the most suitable differential pressure sensor or compact pressure measurement solution for the available installation space and measurement requirements.
What system or line pressures are available for differential pressure transducers?
Differential pressure transducers from Althen are available for different system pressures and static line pressures, depending on the model. For small differential pressures in gases, sensors in the mbar range are available. For wet/wet applications with liquids or gases, versions for significantly higher system pressures are available.
Depending on the series, static line pressures of approximately 100 bar to 600 bar are possible. Some models are designed for working pressure ratings of 160 bar, 250 bar or 400 bar. The available differential pressure measuring ranges vary by sensor and extend from very small mbar ranges to several hundred bar.
When selecting a differential pressure transducer, not only the differential pressure range but also the maximum line pressure, possible one-sided overload, medium, temperature, process connection and output signal should be considered. Althen can help select a differential pressure transducer that safely covers both the required measuring range and system pressure.
For which measuring ranges are differential pressure transducers available?
Differential pressure transducers from Althen are available for very small to very high differential pressure ranges, depending on the model. For fine pressure differences in gases, versions in the mbar range are available, starting from around 0.1 mbar. For industrial wet/wet applications with liquids or gases, sensors with measuring ranges from approximately 35 mbar up to several hundred bar are available.
Depending on the series, the available differential pressure measuring ranges extend approximately from 0.1 mbar to 500 bar. This makes the sensors suitable for applications such as filter monitoring, air and gas flow measurement or cleanroom technology, as well as hydraulic, process and test bench applications.
The right measuring range depends on the medium, static system pressure, possible overloads, required accuracy, process connection and desired output signal. Althen supports you in selecting the right differential pressure transducer for your application.
