Pacific Scientific T5-2001-101-00 Cable Tensiometer

The Pacific Scientific T5-2001-101-00 is a dual-range aircraft cable tensiometer purpose-built for precision tension measurement on control, trim, and secondary cable systems throughout the airframe. Covering a low-range of 10–100 lbs and a high-range of 15–150 lbs, and accommodating cable diameters from 1/16" through 3/16", this instrument gives A&P mechanics and MRO technicians a single tool capable of verifying tension across the broadest spectrum of aircraft cable systems — from light general aviation controls to complex multi-engine and rotary-wing flight control runs.

Why the T5-2001-101-00 Is the Industry Standard

The T5 series has earned its place in maintenance toolkits worldwide because it simply works — reliably, repeatably, and without fuss. Each T5-2001-101-00 leaves the factory fully calibrated with an individual calibration chart unique to that instrument. Converting a dial reading to actual cable tension is as simple as matching the dial number to the appropriate cable size column on the chart — no secondary math, no lookup tables, no guesswork. Because Pacific Scientific engineers the T5 with zero temperature error, the readings you take in a cold hangar on a January morning are just as accurate as those on a hot ramp in July. The instrument requires no preliminary adjustments and no resetting between measurements, allowing technicians to work through a cable rigging check quickly and confidently during scheduled aircraft maintenance or post-maintenance inspections.

Engineered for the Realities of Aircraft Maintenance

• Compact form factor — fits through access panels and confined airframe areas that larger instruments cannot reach
• One-handed operation — complete a cable tension check in seconds without assistance
• Pointer lock mechanism — brake lever rod retains the dial reading so you can remove the tensiometer before viewing the result, ideal in low-visibility locations
• Dual tension range — 10–100 lbs for lighter secondary control cables; 15–150 lbs for primary flight control cable systems
• Multi-cable compatibility — accommodates 1/16", 3/32", 1/8", 5/32", and 3/16" cable diameters using the included riser set
• Temperature-stable accuracy — no mechanical drift in extreme heat or cold, no recalibration required after temperature excursions

Pacific Scientific T5-2001-101-00 Calibration

Like all precision aviation instruments, the T5-2001-101-00 should be recalibrated on a scheduled basis — annually at minimum, or sooner following any overload, shock, or drop event. Pilot John International operates an ISO 17025-accredited calibration laboratory, giving you access to traceable, standards-compliant calibration for your Pacific Scientific tensiometer and a wide range of other precision test and measurement instruments. Our lab technicians are trained to calibrate T5 series tensiometers to the original manufacturer specifications, issuing a fully traceable calibration certificate upon completion. Whether you need a one-time out-of-cycle calibration or want to establish a recurring calibration program for your shop's fleet of instruments, PJi's calibration services deliver the documentation and accuracy your QMS demands.
