Miniaturized Pressure Sensors for Transmission and Clutch Test Benches

Our miniaturized pressure sensors are specifically designed for use in transmission and clutch test benches, providing valid results under the most demanding conditions.

Precise Pressure Measurement for Drivetrain Development

Test benches for drivetrain development place high demands on measurement technology, including high dynamics, extreme temperatures, and intense vibrations. As specialists in miniaturized sensor solutions, DDM Sensors offers the right pressure sensors with compact sizes for high temperature ranges up to 150 °C and fast response times up to 1 kHz.

Advantages of DDM Sensors for Test Benches

Our pressure sensors offer decisive advantages for test bench applications, focusing on accuracy, response time, robustness, and size.

Highest Accuracy and Resolution for Valid Results

Our sensors ensure the necessary measurement quality through minimal deviation (up to ≤ ± 0.25% FS) and high data reproducibility (up to ≤ ± 0.02% FS). This precision forms the basis for an objective and reliable evaluation of transmission and clutch functions during testing.

Extremely Fast Response Time for Highly Dynamic Processes

With a response time of up to 1 kHz, depending on the geometry relative to the pressure sensor, our sensors enable precise detection of rapid pressure peaks, such as those occurring during shifting operations. This allows for seamless data recording, serving as the basis for optimizing control and regulation algorithms.

Maximum Robustness and Durability for Continuous Operation

For demanding continuous operation on the test bench, our pressure sensors are characterized by high overload resistance (up to 400%) and excellent resistance to oils and high temperatures. These properties guarantee reliable performance even over very long test cycles.

Compact Size for Easy Integration

Thanks to miniaturized dimensions (as small as 19.1 mm length / 15.8 mm width) and low weight (approx. 10 g), our sensors can be easily integrated even in very confined spaces. The compact design also ensures minimal interference with the test object and the measurement setup.
