Differential Pressure Sensors
Differential pressure sensors from Sensirion measure thanks to the unique CMOSens® Technology in air and dry gases extremely accurately and offset-free! The digital ASP and the analog SDP family offer extremely high accuracy and resolution, especially in ultra low pressure ranges. The small and cost-effective design makes them an ideal match for price-sensitive solutions, especially in medical and HVAC applications. Reliability, speed and sensitivity have made them the first choice in new medical designs and redesigns. CMOSens® offers unsurpassed long-term stability. Each Sensirion differential pressure device is individually callibrated and temperature compensated due to internal intelligence.
