SDP810-500Pa is a tube-connected digital differential pressure sensor from Sensirion’s SDP800 series with a ±500 Pa measurement range. Its CMOSens® thermal measuring principle shows no zero-point drift and offers long-term stability. With smart averaging functions and several measurement modes it is a preferred choice for precise airflow measurement in cost-sensitive HVAC applications that still need high accuracy.
