The Sensirion differential pressure sensor SDP1108 offers you superior performance at lowest differential pressure levels. The unique performance of the SDP1108 is unequaled thanks to Sensirion's CMOSens® sensor technology.
CMOSens® combines an economical yet highly precise sensor element with electronics for signal processing on a single chip (ASIC). SDP1000 product family is extremely well suited for numerous applications, such as medical applications (homecare ventilation, intensive care ventilation / ICU, invasive ventilation, non-invasive ventilation, neonatal ventilation, CPAP equipment, sleep apnea monitors, anaesthesia equipement, spirometry), HVAC, air and environmental protection, and portable instruments. The housing is made from a high-quality, chemically inert PPS plastic.

Technical Data
The differential pressure is measured by a thermal sensor element. This also enables highly precise measurement below 0.1 cm H20 (10 Pa). In comparison with other differential pressure sensors, which operate according to this principle, only an extremely small amount of air is required thanks to CMOSens® Technology. This also enables reliable and stable operation under very harsh conditions.
