STREAMLINED FLYING WIRE TENSIOMETER

Our flying wire tensiometers are designed to be used in conjunction with a standard dial or beam type torque wrench to easily and accurately indicate the tension on your aircraft's flying and tie wires.

Using the charts below, you can convert the torque wrench readings directly to wire tension readings. The numbers in the left-most column in the charts below are the tension readings in pounds of tension that are on the wire when you have a torque reading that matches the figure on the same line in the column for the  wire size that you are testing. These torque readings are in inch or foot pounds of torque. For example: A 26 foot pound reading on a 7/16 flying wire indicates that the flying wire has 1000 pounds of tension on it.

Torque readings are always taken in a clockwise direction and are read just as the wire makes contact with the anvil on the tensiometer frame. Once the wire contacts the anvil, you'll see a sharp increase in the torque reading. The correct reading will be indicated just prior to that sharp increase. We strongly recommend that you lubricate the threads on your flying wire ends prior to attempting adjustment.

If you have further questions or would like one of these fine products, please contact us via one of the following means: Telephone us at 530-283-2500, fax us at 530-283-0250 or e-mail us at radial@inreach.com

Please note that a flying wire's size is measured at the round, threaded end of the wire, not across the flat. Tie wires are also measured by the thread size and pitch.

In both charts below, RED = Inch-pounds, BLACK = Foot-pounds
and BLUE = Pounds of Tension
