Fermion: LWLP5000 Differential Pressure Sensor

SKU: SEN0343

This high-resolution differential pressure sensor with I2C communication measures pressure difference between two device points. It contains a high-performance MEMS pressure chip and special conditioning chip, providing comparative two-point measurement. Its IC uses a unique multi-stage temperature-compensation algorithm to reduce environmental effects on output. NOTE: Use in clean air to ensure resolution and lifespan; keep water out of nozzles to avoid damage.

    FAQ

    • Hallo, Is there a tax fee for shipping to Indonesia?

      This sensor won't work for long term applications for the following reasons:

      1) The sensor calibration drifts over time
      2) Upon each reboot the sensor calibrates itself. What this means is if you have this installed in an application, but power goes out or your board otherwise loses power, your readings will be reset to zero pressure differential.
