The 9170 mainfall sensor allows for precise measurement of slope in the direction of travel and serves as a junction box to sensors and valves.
The Mainfall Sensor uses the same type of precision electronic device that is used by the Blade Slope Sensor. It mounts under the Hydraulic Manifold Assembly and measures the slope of the machine in the direction of machine travel.
The Mainfall Sensor is a sealed unit and contains no manual adjustments.
The sensor follows the System Four RS-485 communication protocol, developed by Topcon, to provide the first digital communication system available for construction machine automation.
