The Sensirion differential pressure sensor SDP2000 offers you an extended measurement range up to 3500Pa. The unique performance of the SDP2000 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). SDP1000/2000 product family is extremely well suited for numerous applications, such as HVAC (VAV, filter monitoring, ventilator regulation, clean-room monitoring, etc.), medical applications, 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 under 20 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.
