Angle Sensor

Angle sensor is a rotary position sensing device designed to measure angular displacement, rotational position, and direction of motion. It converts mechanical rotation into precise electrical signals for real-time feedback and closed-loop control applications. Widely used in servo motors, robotics, CNC equipment, industrial automation systems, and mobile machinery, angle sensors offer high measurement accuracy, rapid response, excellent repeatability, and stable performance under harsh operating conditions.

Main Types and Principles

• Magnetic Angle Sensor: Magnetic angle sensor is a non-contact device that measures angular position by sensing changes in a magnetic field. As the magnet rotates with the shaft, Hall effect or magnetoresistive elements detect the field variation and convert it into electrical signals. The system then processes these signals to determine the exact shaft position.
• Potentiometer Angle Sensor: Potentiometer angle sensor is a contact-based rotary sensor that measures angle through changes in electrical resistance. When the shaft rotates, a wiper moves along a resistive track, producing a voltage signal that corresponds to the angular position.

Key Specifications and Output Options

• Measurement Range
  The standard measurement range is 0–360° full rotation, suitable for continuous rotation and position feedback tasks in rotating equipment.
• Power Supply
  The sensors support a wide 9–36V DC power supply range, allowing easy integration into most industrial control architectures.
• Accuracy Options
  Two accuracy levels are available depending on control requirements:
  ±0.3° for general industrial positioning
  ±0.1° for precision motion control and servo feedback
• Output Signal Options
  Multiple output interfaces are available for system compatibility:
  Voltage Output (0–10V / 0–5V): for standard PLC and control units
  Current Output (4–20mA / 0–20mA): for long-distance transmission and anti-interference wiring
  Digital Output (RS485 / Modbus / CAN bus): for networked control systems and multi-device communication

Angle Sensor Applications

• Construction and Heavy Machinery: Used in cranes, excavators, asphalt paving machines, and weighing systems for tilt compensation and stable load positioning.
• Rail Transportation: Applied in high-speed trains and passenger rail systems for bogie inclination monitoring and vehicle stability control.
• Marine Systems: Used for pitch and roll measurement, vessel stability control, tanker monitoring, and antenna positioning systems.
• Drilling and Mining Equipment: Provides accurate tilt feedback for directional drilling and equipment alignment in underground and surface operations.
• Mechanical Systems: Supports alignment monitoring, structural tilt detection, and bending control in large mechanical structures and industrial equipment.
• Defense and Aerospace Systems: Used in radar alignment, artillery positioning, navigation support, and mobile platform stabilization systems.
