Position Sensor Installation on Scotch Yoke Actuators
Sensor Selection
1. Inductive Sensors
Detect metallic targets without physical contact. Ideal for non-contact sensing applications where durability is important.
2. Magnetic Sensors
Work with ferromagnetic materials. Excellent for harsh environments where other sensors might fail.
3. Potentiometric Sensors
Provide analog position feedback by measuring changes in resistance. Suitable for precise measurements.
Mounting Requirements
- Identify optimal location near output shaft or yoke mechanism
- Ensure clear line of sight between sensor and target
- Verify no interference from other moving components
- Consider environmental factors (temperature, moisture, vibration)
Installation Process
1 Mounting: Use manufacturer-provided brackets/adapters. Secure firmly to prevent movement during operation.
2 Wiring: Connect sensor wires to control system following the provided wiring diagram.
Calibration & Testing
- Move actuator through full range of motion during calibration
- Adjust sensor settings for accurate position indication
- Perform multiple test cycles to verify reliability
- Fine-tune as necessary for optimal performance
Maintenance Considerations
Regularly inspect the installed sensor and its connections during routine maintenance to ensure continued accurate operation. Check for:
- Physical damage to sensor or wiring
- Loose mounting hardware
- Corrosion or environmental degradation
- Signal consistency throughout the range of motion
