SDP511

DP sensor (+500 Pa) calibrated for mass flow, tube connection

Last time buy: July 26, 2026
 

The digital differential pressure sensors of the SDP500 series provide a digital I²C output, excellent long-term stability and measure with high sensitivity and accuracy even at low differential pressures (10 Pa). Thanks to its high integration level and clever packaging, the reliable CMOSens® sensor can be offered at an economical price. The fully calibrated and temperature compensated sensors are available in different versions. The SDP500 is intended for a direct threaded connection to a pressure manifold via O-ring sealing, while the SDP510 is designed for a tube connection. SDP500 series is designed for high-quality mass production, which makes it an ideal fit for demanding OEM applications.
