The DS85 series of differential pressure sensors are suitable for measuring pressure difference in air or any other non-aggressive gas. Two pressure tappings feed either side of a silicon membrane which deflects to convert the pressure
difference into a 0-10V DC signal. The output is linear and proportional to the pressure difference with respect to the range of the sensor. For example, a difference of
250pA measured on a DS85 with a range of 0-500 Pa will give an output of 5V DC.
The DS85 can be connected directly to ebm-papst EC centrifugal fans with integrated electronics to provide a constant pressure system. When used with a special inlet ring incorporating its own pressure tapping a constant air volume system can also be created.
