Pacific Scientific T5-8002-401-00 Cable Tensiometer

The Pacific Scientific T5-8002-401-00 is the T5-8000 series British/CWT dual-calibration cable tensiometer — the direct counterpart to the T5-2002-401-00 on the heavier-duty T5-8000 platform. It covers 10 through 70 CWT cable sizes across four tension ranges (10–100 lbs, 15–150 lbs, 15–150 lbs, and 25–150 lbs), simultaneously cross-reads on the equivalent standard American inch cable sizes via calibration card T594-101, and is classified by OPTI Manufacturing's service documentation as a full dual-calibration instrument. Two calibration cards ship with every unit: T594-101 for standard inch readings and T610-401B for CWT readings. It is the instrument for multinational MRO facilities, British military programs, and defense maintenance operations that require the broadest CWT coverage in the T5-8000 line — combined with the ~1 lb / 0.45 kg T5-8000 platform robustness that heavy maintenance environments demand.

The T5-8000 Platform for British/CWT Maintenance Programs

The T5-8002-401-00 is functionally equivalent to the T5-2002-401-00 in every calibration respect — same CWT cable sizes (10–70 CWT), same tension ranges, same dual-calibration card set (T594-101 and T610-401B), same standard inch cross-read capability. The distinction is platform: the T5-8000 series weighs approximately 1 lb / 0.45 kg versus the T5-2000 series' 0.77 lb / 0.35 kg, offering greater structural robustness for demanding MRO environments, high-frequency maintenance operations, and programs that specify the T5-8000 series by contract or preference. For maintenance facilities already standardized on the T5-8000 platform for their other tensiometer needs, the T5-8002-401-00 extends that platform choice to their British-spec CWT cable work without requiring a separate T5-2000 series instrument. Zero temperature error ensures accuracy is unaffected by ambient conditions, and no preliminary adjustments are required between uses regardless of environmental conditions.

Broadest CWT Coverage on the T5-8000 Platform

• 10–70 CWT coverage — broadest CWT range in the T5-8000 sub-series, including 70 CWT for specialized British aircraft
• Dual-calibration — OEM-classified as Dual Calibration; reads CWT British and standard inch on the same instrument
• CWT cable sizes: 10, 15, 20, 25, and 70 CWT
• Standard inch cross-read via T594-101 calibration card
• Two calibration cards included — T594-101 (inch) and T610-401B (CWT); select the card for the aircraft specification
• T5-8000 heavier-duty platform — ~1 lb / 0.45 kg; built for demanding MRO and heavy maintenance environments
• 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 low-visibility areas
• One-handed operation — complete a cable tension check in seconds
• No batteries or electronics — fully mechanical, always ready

• Multinational heavy maintenance facilities requiring both CWT and standard inch coverage on the T5-8000 platform
• Defense programs standardized on T5-8000 series instruments extending coverage to British-spec CWT cable work
• Post-repair and return-to-service verification on British-specification aircraft in demanding MRO settings

Pacific Scientific T5-8002-401-00 Calibration

The T5-8002-401-00 should be recalibrated on a scheduled basis — annually at minimum, and immediately following any overload event, mechanical shock, or drop. As a dual-calibration instrument covering both British CWT and standard inch profiles on primary flight control cables, maintaining calibration accuracy across both profiles is essential to airworthiness compliance on every aircraft type it serves. Pilot John International operates an ISO 17025-accredited calibration laboratory capable of recalibrating Pacific Scientific T5-8000 series tensiometers — including dual-calibration 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.
