Technical details and manufacturing context for Angle Sensor

Definition
Within a Load Moment Indicator (LMI) system, the angle sensor is a critical component that precisely measures the boom angle of a crane or lifting equipment. This angular data is a primary input for calculating the load moment (load × radius) to ensure safe operation and prevent tipping or structural overload. The sensor is designed for integration into LMI systems, providing real-time angle feedback to the control unit. It features a measuring range of 0–360° without dead zone, an accuracy of ±0.5° (higher accuracy available on request), and a resolution of 0.1° based on magnetic sensing. The output is an analog ratiometric signal of 0–10 V DC, powered by a supply voltage of 9–36 V DC with reverse polarity protection. The operating temperature range is -40–85 °C (extended range -40–125 °C optional), and the ingress protection rating is IP67 per IEC 60529, suitable for harsh environments. The shaft diameter is available in 6–12 mm (custom sizes available), and the housing material is aluminum (stainless steel optional). The weight ranges from 50–150 g depending on shaft size and housing. The sensor is constructed with electronic components (semiconductors, resistors), a housing of aluminum alloy or engineering plastic, and a stainless steel shaft. These specifications are directory reference ranges and must be confirmed for the actual model and application with the legal manufacturer or supplier. The angle sensor is a component, not a standalone system, and its performance is influenced by the installation, calibration, and the LMI system's requirements. It is essential to verify model-specific values and standards with the manufacturer to ensure compatibility and safety.
Working Principle
The angle sensor operates by measuring a physical change as the shaft rotates. It typically uses one of three principles: potentiometric (change in resistance), Hall effect (magnetic field), or optical encoding. In this product, the magnetic sensing principle is used, providing a resolution of 0.1°. As the shaft rotates, the sensor converts the angular displacement into a proportional analog voltage signal (0–10 V DC). This signal is ratiometric, meaning it varies proportionally with the supply voltage. The sensor is designed to measure the full 360° rotation without dead zone, ensuring continuous angle detection. The output can be interfaced with an LMI control unit for processing.
