Laboratory Vane Shear Apparatus, Motorised
Product Code : JA-ST-9814
The Laboratory Vane Shear Apparatus, Motorised (SKU JA-ST-9814) measures the shear strength of soft cohesive soil specimens in the laboratory. The vane is lowered into the specimen by a lead screw and drive wheel, and an electric motor turns the upper end of a calibrated torsion spring at 0.1° per second. A resettable pointer shows the angle on a dial graduated in degrees, and the dial reading multiplied by the spring factor gives the torque.

Frequently asked questions
At what rate does the vane rotate?
The motor turns the upper end of the calibrated torsion spring to give a rotation of 0.1° per second.
How is the torque worked out?
The resettable pointer shows the angle on the dial graduated in degrees; multiplying that reading by the spring factor gives the torque.
How is the vane lowered into the specimen?
The motor unit is adjusted in height by a lead screw rotated by a drive wheel.
