Produkt-Neuheit

At just 1.2 mm, the ultra-miniature pressure transducer from Sensorade is one of the smallest in the world. A key area of application for such small pressure transducers is aerodynamics, for example in wind tunnels, wind turbines or turbomachinery and turbochargers. In these applications, the installation space is often limited and dynamic, fast pressure measurement is required. For example, the sensor is integrated at neuralgic points on an object in the wind tunnel in order to precisely check how the flows along the object behave.

It is also helpful for turbochargers, which rotate very quickly at up to 100,000 revolutions per minute, if a pressure sensor is particularly small so that it can be attached to the side walls as close as possible to the rotor blades, for example.

Pressure and temperature detection in one sensor

A special feature of the Sensorade miniature pressure transducers is the simultaneous temperature measurement. The temperature has a major influence on the accuracy of the measurement result. The Sensorade sensors permanently record the temperature themselves, which can be taken into account in the measurement result using a calculation formula. In this way, the sensor achieves a very precise pressure measurement result in relation to the actual temperature.

Resonant frequency of 2.7 MHz

The particularly high resonance frequency of 2.7 MHz, which is unrivalled on the market, should also be emphasised. Such an extremely high number of measurements per second is particularly advantageous for dynamic measurements.

In addition to the cylindrical shape in the sizes 1.25 mm and 1.55 mm, a flat version is also available. Flat pressure sensors are suitable for use in wind tunnels, for example, as there is virtually no turbulence even if the sensor is not mounted flush with the surface.

Althen also supplies the measuring amplifier for the sensors, as these initially output a raw signal. The signal amplifier processes the raw signal into a standard output signal. Important for the installation space: The amplifier is built into the associated connector, so that the sensor retains its small size.
