There are two lightweight

purpose designed Tension

( Load ) Cells  in line  with

the reins. The reins are of

a high breaking strain and

very  flexible webbing that

conforms better than a conventional rein to both the bit ring and the Tension Cell. This gives improved rein tension measurement sensitivity, negligible hysteresis, and avoids "dead spots" in measurement due to sloppy rein connections.

The data logger is positioned under the chin and attached to a standard bridle by a 50mm wide velcro band around the bridle chin straps. This position has proven to be well tolerated, quick to mount, and reliable.  

Just taking tension measurements in reins provides an interesting but limited story. In order to answer the question "is the rider or the horse pulling ?", an accelerometer mounted inside the data logger could provide this information.

 

SignalScribe - Rein Tension Meter

Quantify communications between horse and rider for Training and Behavioural Science

The Rein Tension meter measures and continuously records the left and right rein tensions close to the bit. Data is recorded using the versatile 8 channel SignalScribe datalogging system on to a mini SD card typically used in digital cameras.  Measurements could be used for research into equine behaviour,
horse / rider training and
equestrian sport.
