Pacific Scientific T5-8005-111-00 Cable Tensiometer

The Pacific Scientific T5-8005-111-00 is the highest-range instrument in the standard T5 product line — calibrated for primary flight control cable tension measurement from 500 to 2000 lbs on cable sizes 3/16" through 5/16". No other standard T5 instrument in current production exceeds this range. The T5-8005-111-00 exists for the most demanding aircraft primary cable systems in operation — large transport-category aircraft, heavy military platforms, and specialized aerospace programs where primary flight control cable tensions are specified in the range that begins where every other T5 instrument ends. Built on the T5-8005 Ref C mitten-grip platform and delivering the same factory-calibrated, zero-temperature-error precision of the entire T5 line, it is the definitive instrument when only the maximum tension ceiling in the standard T5 product range will do.

The Ceiling of the Standard T5 Line — 2000 lbs

The T5-8005 sub-series defines the upper boundary of standard T5 capability, and the T5-8005-111-00 is its highest point. At 500–2000 lbs across 3/16"–5/16" cables, it covers the extreme tension zone above the T5-8005-110-00's 1600 lb ceiling and extends to the maximum rating the standard T5 platform is designed to handle on conventional cable sizes. One calibration characteristic sets this model apart from every other T5-8005 instrument: a split reading interval structure. Calibration card T597-111 provides 50 lb reading intervals for the 500–1000 lb range and 100 lb intervals for the 1000–2000 lb range — two-tier guidance that reflects the practical resolution needed at the extreme upper end of primary cable tension measurement. The supplementary Table 6-1 within T597-111 provides the reference for the highest readings on 1/4" cable. The riser configuration follows the T5-8005 sub-series standard: Riser #2 for 3/16" cables (not Riser #2C — a critical distinction from the T5-8003 sub-series); Riser #2C for 7/32" and 1/4"; Riser #3A for 5/16". At tension levels approaching 2000 lbs, riser selection accuracy is non-negotiable — always confirm against T597-111 before taking any measurement. Zero temperature error means the instrument is accurate from -53°C to 71°C without any preliminary adjustments.

Maximum Range. Maximum Platform. The T5 Standard Line Ceiling.

• Riser #2 for 3/16" — T5-8005 sub-series pattern; NOT Riser #2C; confirm against T597-111 before every measurement
• T5-8005 Ref C mitten-grip platform — heaviest T5 frame; engineered for extreme-tension cable work and cold-weather heavy maintenance
• Zero temperature error — calibration-stable from -53°C to 71°C, no adjustment required
• Pointer lock brake lever — retains reading before removal in confined or overhead access areas
• One-handed mitten-grip operation — operable at the maximum T5 tension ceiling with heavy gloves
• No batteries or electronics — fully mechanical, always ready

Pacific Scientific T5-8005-111-00 Calibration

The T5-8005-111-00 should be recalibrated on a scheduled basis — annually at minimum, and immediately following any overload event, mechanical shock, or drop. At tensions up to 2000 lbs on primary flight control cables, calibration currency is a fundamental safety-critical maintenance requirement. A calibration error at the maximum T5 tension range represents the largest absolute tension deviation possible on a standard T5 instrument, with direct airworthiness implications on the primary cable systems of the largest aircraft in service. Pilot John International operates an ISO 17025-accredited calibration laboratory capable of recalibrating Pacific Scientific T5-8005 series tensiometers to original manufacturer specifications, issuing a fully traceable calibration certificate upon completion. Whether your maintenance program operates under FAA oversight, a DOD contract, or an ISO 9001 quality management system, PJi's lab delivers the traceability and documentation your compliance requirements demand.
