Technical details and manufacturing context for Grade Sensor

Definition
A Grade Sensor is a critical component within a Grade Control System, designed to precisely measure the inclination, slope, or grade of a surface (e.g., on construction machinery, agricultural equipment, or industrial platforms). It provides real-time angular data to the control system, enabling automated adjustments to maintain a desired grade or level during operations such as excavation, grading, paving, or material handling.
Working Principle
Typically utilizes inertial measurement principles, such as MEMS (Micro-Electro-Mechanical Systems) accelerometers or gyroscopes, to detect changes in orientation relative to gravity. It measures the tilt angle by sensing the gravitational force component along its axes. The sensor's output (often an analog voltage or digital signal proportional to the angle) is transmitted to the system's controller for processing and corrective action.
Common Materials
Silicon (MEMS wafer), Epoxy resin (encapsulation), Copper alloy (leads/contacts)
