Applications for Miniaturized Low Pressure Sensors
Low pressure sensors from DDM Sensors are used in filter monitoring, variable air volume regulation (VAV), room pressure monitoring in cleanrooms, medical technology, and laboratory engineering. In industrial automation, they are deployed for pneumatic control systems and vacuum monitoring. A central field of application is leakage testing, where, for instance, a differential pressure sensor with a 50 mbar range measures the pressure drop between a reference volume and the test volume with ultra-high resolution to detect the smallest leaks.
Custom Low Pressure Sensors by DDM Sensors
Modification options for our low pressure sensors include customized measuring ranges and specific process connections that deviate from our standard options. Our proven process accompanies you from initial technical requirements through engineering to the finished prototype. If you require an individual sensor solution, our technical advisory team is available at any time to develop the optimal solution for your requirements.
