Pacific Scientific T60-1002-C9-00 Cable Tensiometer

The Pacific Scientific T60-1002-C9-00 is the British/CWT high-range model of the T60 series — delivering the riser-free, direct-reading platform of the T60-1001-C9-1A to maintenance programs working on British CWT-specification primary flight control cables. It covers five CWT cable sizes from 10 CWT through 45 CWT at a single unified tension range of 150–450 lbs, reading tension directly from the dial in pounds without a calibration chart, conversion table, or interchangeable risers. It is the CWT British counterpart to the T60-1001-C9-1A and the high-range companion to the T60-1002-C8-00 within the T60 British/CWT family.

The T60 High-Range Platform for British CWT Primary Control Cables

Where the T60-1002-C8-00 covers the lighter 3–45 CWT cable sizes at tensions up to 200 lbs, the T60-1002-C9-00 is calibrated for the five larger CWT cable sizes — 10, 15, 25, 35, and 45 CWT — at the 150–450 lb primary flight control tension range. The 3 and 5 CWT sizes are not included because lighter cables of that diameter do not carry tensions in the C9 range. The unified 150–450 lb range across all five CWT sizes means there is no range-switching by cable size group — unlike the T60-1002-C8-00's three tension sub-ranges, the C9-00 reads 150–450 lbs consistently for every CWT cable size it supports. The workflow is the same as the T60-1001-C9-1A: the built-in cable diameter gauge identifies the cable, the technician presets the dial to the CWT cable size marking, and tension is read directly from the dial in pounds. For technicians already familiar with the C9-1A on standard inch cables, the T60-1002-C9-00 requires no additional training — the handling is identical, the range is the same, and the only difference is the CWT preset positions on the dial. Each unit ships with a serialized calibration bar preset to the 10 CWT position for C9 British model accuracy verification; a reading within ±2% of the bar's tag value confirms the instrument is in specification. Zero temperature error means accuracy is unaffected from -65°F to 160°F without any adjustments.

High-Range CWT Direct Reading. Five Cable Sizes. No Risers.

• 150–450 lb unified range — single range across all five CWT cable sizes; same ceiling as T60-1001-C9-1A
• Five CWT cable sizes: 10, 15, 25, 35, 45 CWT — the mid-to-large CWT primary control cable range
• Direct-reading dial — tension in pounds displayed directly; no chart conversion required
• No risers required — handles all five CWT cable sizes with no accessories to select or manage
• Built-in cable diameter gauge — integrated gauge identifies CWT cable size directly on the instrument
• 3-point positive cable grip — essential at primary cable tension levels for stable, accurate measurement contact
• Push-button pointer lock — holds dial reading precisely before removal in confined or low-visibility areas
• Serialized calibration bar — preset to 10 CWT; serial-matched field accuracy verification within ±2%
• USAF Type C9 equivalent — British/CWT version of the C9 designation
• Zero temperature error — calibration-stable from -65°F to 160°F, no adjustment required
• No batteries or electronics — fully mechanical, always ready

Typical Applications

• British-origin and Commonwealth aircraft primary control cable tension verification at 150–450 lbs on 10–45 CWT
• RAF and British military programs requiring riser-free high-range CWT cable tension measurement
• Multinational MRO facilities pairing T60-1001-C9-1A (inch) with T60-1002-C9-00 (CWT) for complete high-range coverage
• Primary control cable rigging and post-rigging verification on British-specification aircraft
• British-spec aircraft programs where the T60-1002-C8-00's 200 lb ceiling is insufficient for primary cable tensions
• Post-repair and return-to-service verification on high-tension British CWT primary cable systems

Pacific Scientific T60-1002-C9-00 Calibration

Like all T60 series instruments, the T60-1002-C9-00 should be recalibrated on a scheduled basis — annually at minimum, and immediately following any overload, mechanical shock, or drop event. Each unit ships with a serialized calibration bar for pre-use field accuracy verification: preset the dial to the 10 CWT position, place the instrument on the calibration bar, compare the reading to the bar's tag value, and confirm it is within ±2% before use. This field check confirms current accuracy but does not replace formal annual recalibration. Pilot John International operates an ISO 17025-accredited calibration laboratory capable of recalibrating Pacific Scientific T60 series tensiometers — including British/CWT models — to original manufacturer specifications, issuing a fully traceable calibration certificate upon completion. Whether your maintenance program operates under FAA oversight, UK CAA requirements, a DOD contract, or an ISO 9001 quality management system, PJi's lab delivers the traceability and documentation your compliance requirements demand.
