Pacific Scientific T5-2001-104-00 Cable Tensiometer

The Pacific Scientific T5-2001-104-00 is the highest-range instrument in the T5-2001 sub-series — the model shops reach for when primary flight control cable tensions exceed what lighter-duty tensiometers are rated to measure. With a low range of 30–200 lbs for cable sizes 1/16", 3/32", and 1/8", and a high range of 30–300 lbs for 5/32" and 3/16" cables, it covers the upper end of the tension spectrum found in larger general aviation aircraft, turboprops, light twins, and military platforms. Carrying the U.S.A.F. C5 designation, the T5-2001-104-00 is qualified for military aviation maintenance programs and is supported by the same proven T5-2000 series platform trusted by commercial and defense MROs worldwide.

When Mid-Range Isn't Enough

Aircraft primary control cable tensions vary significantly by airframe type and size. Many GA aircraft operate their flight control cables in the 50–150 lb range, but larger singles, twins, and turboprops routinely specify primary cable tensions well above that — sometimes reaching 200–300 lbs on elevator and aileron runs. The T5-2001-104-00 is purpose-matched for that upper tier. Its dual range means a single instrument covers both the lighter secondary control cables and the heavier primary runs on the same airframe without swapping tools. Each unit ships factory-calibrated with its own individual calibration chart (T595-104), providing direct dial-to-pounds conversion for every supported cable size. The T5 series is engineered with zero temperature error — accuracy is maintained in extreme heat or cold without any adjustments, preliminary setup, or rechecking between measurements.

Precision Where It's Needed Most

• Upper-range dual coverage — 30–200 lbs for small cables; 30–300 lbs for mid-size cables
• Full five-size compatibility — 1/16", 3/32", 1/8", 5/32", and 3/16" aircraft control cables
• Pointer lock brake lever — retain the dial reading before removing the instrument from the cable
• One-handed operation — complete a cable tension check in seconds, no assistance required
• Zero temperature error — calibration-stable from extreme cold to high heat
• U.S.A.F. C5 qualified — suitable for military aviation maintenance programs
• No batteries or electronics — fully mechanical, no power source required
• Compact form factor — fits through small access panels and confined airframe areas

Pacific Scientific T5-2001-104-00 Calibration

The T5-2001-104-00 requires recalibration on a scheduled basis — annually at minimum, and immediately following any overload event, mechanical shock, or drop. Because this instrument is used on primary flight control cables where under- or over-tension has direct safety implications, maintaining calibration currency is especially important. Pilot John International operates an ISO 17025-accredited calibration laboratory capable of recalibrating Pacific Scientific T5 series tensiometers to original manufacturer specifications, with a fully traceable calibration certificate issued upon completion. Whether your program operates under FAA oversight, a DOD contract, or an ISO 9001 quality management system, PJi's calibration services provide the documentation your compliance requirements demand.
