The BT-33-75D Cable Tension Gauge, also known as the BT3375D, is a mechanical tensiometer designed to accurately measure the tension in small-diameter aircraft control cables. Manufactured by Arete Manufacturing, this tool is widely used in aviation maintenance to ensure that control cables are properly tensioned, which is critical for safe and responsive aircraft operation.
Key Features and Uses
- Cable Compatibility: The gauge is designed for use with 1/16″, 3/32″, and 1/8″ diameter cables, which are common sizes in aircraft control systems.
- Tension Range: It measures cable tension within a range of 10 to 70 pounds, providing readings with an accuracy of ±10% .
- Ease of Use: Operation involves squeezing the ball handle, placing the gauge on the cable, releasing the handle, and reading the tension directly from the dial. This straightforward process eliminates the need for conversion charts
- FAA Approval: The BT-33-75D is FAA-NR approved, indicating its acceptance for use in aviation maintenance tasks
Applications
This tension gauge is primarily used in the aviation industry for:
- Routine Maintenance: Ensuring that control cables are within specified tension limits during regular inspections.
- Post-Installation Checks: Verifying proper tension after cable installation or replacement.
- Safety Assurance: Maintaining correct cable tension is vital for the safe operation of flight control systems.
