Product Details
High Precision Load Cell & Highway Overload System & Weigh
In Motion Sensors
Product Description
The quartz sensor with quartz crystal as the "core" has perfect
linear output and consistent repetitive weighing output signals,
ensuring accurate weighing stability, no signal drift and easy
calibration. At the same time, the unique cutting process of quartz
crystal and the unique structural form of the sensor determine its
insensitivity to lateral forces (forces other than vertical
downward), Therefore, even when the vehicle passes through the
sensor, the behaviors such as braking, acceleration and direction
change will not affect the weighing accuracy of the system.
