Abstract
Aiming at the insitu detection for the cable tension of cable-stayed bridge and shortage of the existing cable tension sensor
a new insitu cable tension sensor based on magneto-elastic effect is introduced
it’s principle is described
the factor of effect is analyzed.The experiment system is designed
the experiment of pulling tension is carried on
the experiment results indicated that dynamic characteristic is good
it’s repetition error is ±0.2 %
adapt to requirement of insitu measurement cable tension.
