GRADER WATCHMAN-3
Grader Slope Meter
GRADER WATCHMAN-3 is a grader slope meter that is used for control and monitoring of the blade slope of different graders. The device allows the operator to keep the blade slope at a desired angle with the aid of sound and light signals.
The device comes with two separate units:
Control unit
High accuracy wireless slope sensor
The slope sensor is connected to the grader blade and the control unit is attached to the window of the cabin, allowing the operator to view the measurement results and alarms directly from the cabin.
GRADER WATCHMAN-3 allows the operator to keep the blade slope at a desired angle with the aid of sound and light signals. Additionally, the device allows the operator to measure slope of an existing surface by lowering the blade of the grader to the desired surface location and then taking the measurement.
GRADER WATCHMAN-3 Features and Benefits
Wide slope measuring range
Adjustable blade turnout angle compensation
Alarms and signals to help keep the blade slope at desired angle
Measurement with display
Wireless sensor is easy to install and requires less cabling
Can be used during construction or to measure slope of existing surfaces
