SDP600 Series - Differential Pressure Sensors
With the SDP600 series, Sensirion provides the first digital, dynamic differential pressure sensor. The sensor has a digital I²C output and measures with highest sensitivity and accuracy even at low differential pressures (< 10 Pa). Its excellent long-term stability makes drift issues a thing of the past. Thanks to its exceptional integration level and clever packaging, the small, fast and reliable CMOSens® sensor can be offered at an economical price.
The fully calibrated and temperature compensated sensors are available in different versions. The SDP600 is intended for a direct threaded connection to a pressure manifold via O-ring sealing, while the SDP610 is designed for a tube connection. SDP600 series is designed for high-quality mass production, which makes it a perfect fit for demanding OEM applications.
