Micro Cross Plate Shear InstrumentIt consists of 1 spring torsion meter, 3 cross plate heads of different sizes, and 1 internal hexagonal wrench. Using three different plate heads, the testing range is 0-0.2, 0-1, and 0-2.5 kg/cm2. The dial scale is divided into 50 scales, and the testing accuracy is better than 5%.

1Micro Cross Plate Shear InstrumentProduct Features

1. Portable instrument, with a total weight of 0.8kg
2. Different models of cross plate heads can achieve different ranges and testing accuracies
3. Precision stainless steel integrated cross plate head, not easy to break
4. All metal structure, durable and cost-effective
5. Separated packaging boxes for easy carrying and better protection

The scale range of one circle on the dial corresponding to the middle plate head (standard) is 0-1kg/cm2, and the minimum displayed scale is 0.02 kg/cm2; In addition to the standard plate head, the other two plate heads have ranges of 0-2.5kg/cm2 (small) and 0-0.2kg/cm2 (large), respectively.

2、 Board head description

This product includes 1 torque meter and 1 small, 1 medium (standard), and 1 large plate head each. When using a standard plate head, the dial reading is the actual shear strength value. When using small and large plate heads, the dial readings should be multiplied by 2.5 and 0.2 respectively to obtain the actual shear strength.

3、 Operation steps

1. Grasp the handshake of the instrument and turn the pointer counterclockwise (with your fingers) to align with the zero position of the dial

2. Select a sample with a flat surface and appropriate size (generally the diameter of the soil sample area, not less than 3 times the diameter of the plate head used).

3. Estimate the shear strength of the soil sample and select a suitable plate head (usually a standard plate head can be used for testing first). Place the plate head perpendicular to the surface of the soil and press it into the soil sample below the depth of the plate head teeth. Maintain appropriate vertical pressure and rotate the handshake clockwise at a rate of 5-10 seconds per cycle until the soil is sheared and destroyed.

Tip: Once the soil is cut, the pointer on the dial will remain unchanged.

4. After the soil is sheared and damaged, slowly release the spring torque, that is, slowly lift out the instrument. Before manual reset (i.e. step 1), the dial reading indicated by the pointer ismaximumShear strength value (i.e. soil shear strength).
