Our Services: Pressure Sensors and Test Bench Engineering

We offer comprehensive solutions ranging from specialized pressure sensors to customized test bench engineering. Discover our entire portfolio of pressure sensors or learn more about our expertise in test bench construction.

Challenges of Pressure Measurement in Modern Test Benches

Central challenges in testing often include limited installation space requiring complex integration, as well as high dynamic loads caused by vibrations and pressure peaks. Simultaneously, the requirement for exact and reproducible measurement results under extreme thermal loads—covered by our sensors with operating temperature ranges from -40 °C to +150 °C—is crucial for valid test results. Furthermore, thanks to materials such as 1.4404 and 1.4435, our sensors are designed for compatibility with various liquid and gaseous test media.

Our Pressure Sensor Series for Test Bench Technology

Our entire range of pressure sensors is relevant for test bench technology, characterized by a focus on miniaturization without compromising performance.

All series are suitable for liquid and gaseous media and offer specific advantages for different requirements. The PV-25 and PX-25 series are suitable for simpler applications with sufficient installation space, while the PV-22 and PX-22 series are designed for wide temperature ranges from -40 °C to 125 °C (optionally up to 150 °C).

For small installation spaces, we offer the PV-15 series, which also operates across a wide temperature range. For the smallest spaces and high temperatures up to 150 °C, our PV-10 pressure sensor is the ideal solution. For precise detection of pressure differences, our PV-2722 differential pressure sensor is perfectly suited.

Developed for the Highest Demands in Test Bench Engineering

Measurement Accuracy You Can Rely On

Our accuracy is based on a low total error that combines the effects of linearity, hysteresis, and reproducibility, typically at ≤ 1% of the measuring range. This ensures reliable and precise results. Our sensors feature high thermal stability and long-term stability of up to ≤ 0.1% per year. To document the specified accuracy, every sensor is supplied with a factory calibration certificate as standard.

Seamless Integration into Your System Environment

You can choose from a variety of electrical connections such as M12, MIL, Lemo, or various cable options. Our sensors provide standardized analog output signals, including 0.5 to 4.5 V, 1 to 6 V, and 4 to 20 mA. Additionally, we provide a wide selection of standard and custom process connections to simplify mechanical integration. To support your engineering process, we provide detailed CAD data and comprehensive technical documentation.

Durability and Robustness for Continuous Operation

We exclusively use high-quality, wetted materials such as stainless steel grades 1.4404 and 1.4435 for demanding continuous operation in test benches. All models feature high shock and vibration resistance and are designed for high load cycle counts. Overload protection of up to 400% of the measuring range reliably protects the sensor against unforeseen pressure peaks and helps maximize its service life.

Typical Application Areas for Our Pressure Sensors

Our miniaturised pressure sensors are used in a wide range of applications within test bench technology:

• Engine Test Benches: For measuring oil pressure, fuel pressure, boost pressure and coolant pressure. 

• Gearbox Test Benches: For monitoring hydraulic and lubrication pressure. 

• Component Testing: For the validation of pumps, valves, filters and injectors. 

• Hydraulic and Pneumatic Test Benches: General pressure measurement tasks. The robust PV-25 and PX-25 series are ideal for this purpose.

• E-mobility Test Benches: Monitoring of cooling circuits for batteries and power electronics, often at elevated temperatures, for which the PV-22 and PX-22 series are ideal. 

• Hydrogen Applications:  Use in fuel cell test benches, where the PV-2722 differential pressure sensor can be used for monitoring. 

• Turbocharger and Brake Test Benches:  Measurement of highly dynamic pressures in the smallest of spaces using the PV-15 and PV-10 series. 

Test Bench Development with DDM Sensors

We realize test benches that operate in wide temperature ranges from -40 °C to 150 °C and are equipped with high-precision measurement technology. Our development process is standardized and transparent: to respond exactly to your requirements, we recommend a procedure based on a detailed functional and technical specification document (lastenheft/pflichtenheft). This ensures that all technical specifications are clearly defined and implemented in the final result.
