Technical details and manufacturing context for Grade Sensor

Definition

A Grade Sensor is a component used in grade control systems to measure the inclination, slope, or grade of a surface. It is commonly applied on construction machinery, agricultural equipment, and industrial platforms. The sensor provides real-time angular data to a control system, enabling automated adjustments to maintain a desired grade or level during operations such as excavation, grading, paving, or material handling. The sensor typically uses inertial measurement principles, such as MEMS accelerometers or gyroscopes, to detect orientation relative to gravity. It measures tilt angle by sensing gravitational force components along its axes. Output is often an analog voltage or digital signal proportional to the angle, transmitted to a controller for processing and corrective action. Key parameters include a measurement range of -45 to 45 degrees, accuracy of ±0.1 degrees at 25 °C, resolution of 0.01 degrees, and a 4-20 mA analog current loop output. Supply voltage is 9-36 V DC with reverse polarity protection. Operating temperature range is -40 to 85 °C. The housing is anodized aluminum, with an ingress protection rating of IP67 (dust-tight and immersion up to 1 m) per IEC 60529. Vibration resistance is 20 g (10-2000 Hz) per IEC 60068-2-6, and shock resistance is 100 g (11 ms half-sine) per IEC 60068-2-27. Approximate weight is 200 g. Materials include silicon (MEMS wafer), epoxy resin (encapsulation), and copper alloy (leads/contacts). These specifications are typical reference values; verify model-specific data with the manufacturer or supplier before procurement.

Working Principle

The sensor operates on inertial measurement principles, using MEMS 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 output, often an analog voltage or digital signal proportional to the angle, is transmitted to the system's controller for processing and corrective action.
