SENSIRION SDP600 Series (SDP6xx/5xx) Low-cost Digital Differential Pressure Sensor
The SDP600 series is a family of low‑cost digital differential pressure sensors from Sensirion, designed for high‑volume applications such as medical, HVAC, automotive, and process automation. The sensors measure air and non‑aggressive gases with high accuracy and feature a 2‑wire I2C digital interface.
Key features include operation from a 3.3 V supply, selectable pressure ranges up to +500 Pa, 12‑bit resolution, temperature compensation, and robust mechanical designs suitable for wave‑soldering. The datasheet also covers OEM customization options, mechanical mounting details, and handling instructions.

How should SDP600 sensors be stored before use?
Store them in the original ESD tray packaging or in ESD bags, keep the environment dust‑free, and maintain a temperature of 0 °C to 50 °C (‑40 °C to 80 °C for limited time).
From: Sensirion SDP600 Series Differential Pressure Sensor Handling Instructions Application Note
What handling precautions are required during assembly?
Protect the sensor ports from dust, solder flux, and liquids, avoid any mechanical force on the pins, and handle the sensor only in an ESD‑protected area with grounded personnel and equipment.
From: Sensirion SDP600 Series Differential Pressure Sensor Handling Instructions Application Note
How can the pressure drop in a hose be compensated when using an SDP600 sensor?
Calculate the hose pressure drop using the Hagen‑Poiseuille based formulas and add it to the sensor reading (Ap_hose + Apsensor).

What hose inner diameter can be used to neglect pressure drop?
Hoses with an inner diameter of 6 mm or larger can be used, as the pressure drop becomes negligible.
