Important selection criteria for industrial pressure transducers
When selecting a suitable industrial pressure transducer for your application, several key factors should be considered to ensure optimal performance and system compatibility:
1. Type of medium: Gas or liquid
Check whether the sensor is suitable for gaseous, liquid, or aggressive media.
Materials such as stainless steel or special coatings provide protection against corrosion.
2. Pressure range and overpressure resistance
Select the appropriate measuring range, such as 0–10 bar or 0–1,000 bar, according to your application.
Check whether the sensor can also withstand temporary overpressure or pressure peaks.
3. Accuracy and resolution
Most standard pressure transducers provide excellent accuracy for industrial applications.
For precise control and regulation processes, long-term stability is equally important.
4. Temperature range
Consider the permissible temperature range for both the medium and the surrounding environment, for example from −40 to +125 °C.
Optional temperature compensation can ensure stable measurement results under changing environmental conditions.
5. Design and installation space
Miniature versions are suitable for applications with limited installation space.
Compact designs make integration into existing systems easier.
6. Explosion protection (ATEX)
An ATEX-certified sensor is required for hazardous areas in the process industry, chemical industry, or energy sector.
7. Output signal and compatibility
Select the output signal according to the control system, such as 4–20 mA, 0–10 V, ratiometric, or digital signals such as I²C or CAN.
Check whether the signal is compatible with the existing PLC or display unit.
8. Service and product lifecycle
Calibration options, repair services, and the long-term availability of spare parts help control operating costs and ensure system availability.
Althen offers suitable services to support these requirements.

Frequently asked questions about General purpose pressure sensors
Answers to the most important technical questions
Which process connections are used for high-pressure transducers?
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.
Are custom pinouts available for industrial pressure transducers?
Yes. Depending on the model, industrial pressure transducers can be supplied with different electrical connections and pinouts. The standard pressure transducer pinout is specified in the relevant datasheet and depends on factors such as the output signal, wiring configuration and connector type, for example a 2-wire, 3-wire or 4-wire connection.
Many pressure transducers are available with different electrical connection options, including DIN connectors, M12 connectors and cable outlets. For the M20, for example, connection options include a 4-pin DIN connector, a 4-pin M12 connector and a PUR cable. Available output signals include 4–20 mA, 0–5 V, 1–5 V and 0–10 V, depending on the model.
A custom pinout or alternative electrical connection may be possible depending on the sensor model and application. The AGS4200 pressure transducer is available with different output and electrical connection options. For applications involving existing wiring, replacement sensors or customer-specific integration, the required pinout and connector configuration should therefore be specified before ordering.
Are industrial pressure transducers available for hydraulic pressures of 250–350 bar?
Yes. Althen offers industrial pressure transducers for hydraulic applications with typical pressure ranges such as 250 bar and 350 bar. These pressure ranges are commonly used in hydraulic systems, test benches, machine control systems and mobile machinery.
When selecting a hydraulic pressure transducer, not only the nominal pressure range should be considered, but also possible pressure peaks, overpressure capability, process medium, temperature range, process connection and output signal. Robust pressure transducers with suitable process connections and industrial output signals such as 4–20 mA or 0–10 V are commonly used in hydraulic applications.
Suitable pressure transducers include the MPM4511, AGS4200 and MPM380. These models cover typical high-pressure ranges in hydraulic systems and are designed for liquids and demanding industrial environments.
Althen can help select the appropriate industrial pressure transducer for your hydraulic application, including pressure range, connection, accuracy and electrical integration.
Ik vind dit beter dan de huidige Engelse versie om twee redenen. “Hydraulic pressures of 250–350 bar” klinkt natuurlijker dan “hydraulic measuring range (250–350 bar)”, en hydraulic pressure transducer staat nu op een logische plek in het antwoord als exacte relevante zoekterm.
De opmerking van de Duitse collega over de AST2000 is in deze versie ook goed verwerkt: die wordt niet genoemd en de AGS4200 staat juist expliciet tussen de aanbevolen modellen.
