Sensor-Technik Wiedemann (STW) has performed further qualification tests on its M01 pressure sensors and found them to be practically indestructible. Customers can therefore rest assured that M01 pressure sensors will cope with virtually any industrial environment.
Although M01 pressure sensors have already proven their robustness in numerous applications over many years, standardised tests provide an additional, objective confirmation. Therefore, verification in accordance with the ISO 16750-3 and DIN EN 60068-2-80 standards was conducted, requiring extremely stringent test conditions.
Over a total of 282 hours (more than 11 days), the M01 pressure sensors were subjected to vibrations with frequencies up to 2000Hz and accelerations of 18 'g' in three axes, with simultaneous temperature cycles of between -40 and +125degC. The test setup alone required a high level of development effort including 3D modelling and FEM simulations. While the pressure sensors themselves emerged from the test undamaged, both the test bench and the supply lines and plugs had to be repaired or replaced multiple times.
In addition to this now-certified extreme durability, the M01 pressure sensors also benefit form excellent long-term stability. It is possible to select different components and to combine the pressure range, pressure connection, electrical signal and electrical connection to match the needs of almost any application. There are even variants available for measuring hydrogen pressure. For the further processing of the sensor data, STW offers access to the open IoT platform machines.cloud via its control systems and telemetry modules.
