The document outlines the technical specifications for the ddedde--0088 sensor, designed for vehicles with air suspension, including its voltage ranges and error tolerance. It details the installation process, warning about high pressure, and provides calibration methods for axle load sensors. The sensor's output signal is linear and stable, independent of the onboard supply voltage.

DDE-08 is preferably installed into the standard
hole of main supply air cushion of vehicle air
suspension (instead of screw-cap/plug).
Can be installed into any convenient location using
a T-splitter.
