Mechanical Aircraft Cable Tension Meter

The Model ACM series of Aircraft Cable Tension Meters are designed to precisely measure static tensions in aircraft cables. Use with flexible cables with diameters from 1/16” up to 1/4”, CWT cable sizes from 5 to 25 and tension from 5 to 600 pounds.

OPERATION:

First select the cable size and the associated Riser from the instrument’s selection chart on the back of the instrument. Rotate the Riser so that the appropriate Riser number is facing you. Then separate the instrument’s outer cable contact guides by rotating the engagement lever open and hanging the instrument onto your tensioned cable. Then rotate the lever closed to engage the instrument onto the cable allowing your cable to automatically drop into place. Read the number under the needle on the dial face and then convert that number to a tension value by cross referencing the numbers on the Material Selection Chart.

STANDARD FEATURES OF ALL MODELS

Calibration:

Tensitron calibrates instruments using the “free hanging weight” method. This means that we vertically suspend an accurately-sized cable, attach a NIST-certified weight to the bottom of it, engage the instrument on the cable, and the tension reading on the instrument will correspond to the amount of the weight. If you require a different calibration method, please contact Tensitron.

To verify the accuracy of your Tensitron meter, use the “free hanging weight” method as a standard rather than comparing your meter’s readings to those of another gauge. Also do not use a tensioning device that converts rotational torque into tension values, and do not simulate tension using a calibration bar, because these systems are often inaccurate and may damage your meter. If you need assistance, please refer to your meter’s Operating Instructions or contact Tensitron.
