There is enough clearance in the head area to allow rotation of the face plate and thus torsional force is transmitted to the torque cell. Product Support: www.instron.com... - Page 32 Chapter: Operation • When the clamp lever is put in the disengaged (horizontal) position, the torque cell assembly is pushed forward in the housing so that each engagement pin is in the neck of its slot (2e). The neck area has minimal clearance and does not allow the face plate to rotate, and thus no torsional force is transmitted to the torque cell.
