High-precision tilt sensors enable medical automation equipment to operate stably and efficiently.

Customer Background

A medical equipment manufacturer specializing in medical rotary assembly machines and automated production lines. Their systems are mainly used for the assembly and inspection of precision medical devices.

During operation, the equipment requires real-time monitoring and closed-loop control of the rotary platform angle to ensure assembly accuracy and product consistency.

Project Requirements

The customer outlined several key requirements:

• High-precision angle measurement with minimal error
• Fast response speed to match high-speed assembly cycles
• Stable performance over long operating periods to reduce calibration frequency
• Strong resistance to vibration and shock for high-speed machine environments
• Support for industrial communication interfaces for easy integration into existing control systems

Solution

For this project, our HCA516/526T series tilt sensors were selected. Key specifications include:

• Measuring range: ±10° / ±30° / ±60° / ±90° optional
• Resolution: 0.001°
• Accuracy: up to 0.005° (@25°C)
• Long-term stability: as low as 0.01°
• Zero Temp.coefficient: 0.0005 ° / ℃
• Sensitivity Temp.coefficien: ≤50 ppm/C
• Response frequency: 20Hz, with output rate up to 100Hz
• Output interfaces: RS232 / RS485 / RS422 / TTL / MODBUS

Implementation

The sensor is installed on the key axis of the rotary assembly platform. By continuously capturing tilt data and transmitting it to the PLC control system, it enables:

• Precise positioning of the rotation angle
• Dynamic compensation during motion
• Alarm and correction for abnormal angle deviations

Results

After implementation, the customer achieved significant performance improvements:

• Over 20% improvement in assembly angle accuracy
• Enhanced repeatability and positioning consistency
• Extended maintenance and calibration intervals due to excellent long-term stability
• Reliable and stable output even under high-speed operating conditions
