Non Contact Tension Meter

Digiforce from Applied Measurements Ltd, UK is a non contact tension meter, mainly meant for measurement of tension in the wire and strands in the precast concrete fabrication. Other areas are aerial ropeways, cable car, wire rope in lifts, power lines/towers, cranes and winches. It works on the principal that when a tensioned member anchored between two points is struck, it vibrates at a particular frequency, which is directly related to its tensile stress. Digiforce needs the length of the member close to ±5 mm and weight of the member in grams/meter to be keyed in and held close the vibrating member (after it is struck once to start the vibration). Vibration frequency is picked up, internal calculation is done and the display shows the tension force.
