1. A load sensor arrangement for installation on a vehicle axle of a vehicle, the load sensor arrangement comprising:
a non-invasive load sensor for measuring a load subjected to the vehicle axle;
a sensor holder comprising a sensor holding portion and a mounting portion; the
mounting portion configured for arrangement to the vehicle axle; and
an attachment element for releasable connection of the non-invasive load sensor to the sensor holding portion;
wherein:
the non-invasive load sensor comprises a magnetic sensor configured to measure a change in an inductive response from the vehicle axle by applying a magnetic field to the vehicle axle, or an optical sensor;
the sensor holding portion is configured to hold the non-invasive load sensor in a position for direct measuring on the vehicle axle;
the sensor holding portion comprises a protective bracket arranged to at least partly cover the non-invasive load sensor on a side of the non-invasive load sensor facing away from the vehicle axle; and
the attachment element comprises a spring element extending from the protective bracket towards the non-invasive load sensor for applying a force on the non-invasive load sensor for maintaining the non-invasive load sensor in the position.
