    DMTY miniature earth pressure box 
    Introduction:
    DMTY series strain-type earth pressure cell is suitable for measuring the stress of sand body in or around soil, mud, sand and model pile in model test. The strained full-bridge circuit can accurately eliminate the influence of temperature changes on the instrument. There are two ways of outlets: side outlet and bottom outlet. The smallest product size can be customized with a diameter of 10mm
    Technical Parameters:
    Diameter (mm) 12 16 20 28 40 48 80
    Thickness (mm) 4.2 4.8 6.5 6.5 10 10 25
    Range 0.05-10 (MPa) (range customization)
    Accuracy ≤0.5% F • S (Note: F • S is the full-scale output value)
    Bridge resistance 350 (Ω) full bridge
    Full scale output Around 1000, up to 3000 micro-strain, the smaller the diameter, the smaller the full-scale output
    characteristic Static and dynamic measurement
    Outgoing way Side outlet, bottom outlet
    Wiring method Red yellow blue black connection A B C D
    K Strain amplifier sensitivity coefficient K = 2.0
    Remarks Size and range can be customized
    Grouped equipment DMYB series dynamic and static strain acquisition instrument
    Sensor principle and structure:
    The earth pressure cell adopts the principle of strained full-bridge circuit. The high-precision full-bridge strain gauge is pasted inside the sensor sensing membrane. When the external pressure acts on the surface of the sensing membrane, the membrane is deformed and transmitted to the strain gauge, which causes strain Change, use strain collection equipment to collect the strain change information and process the calculation, you can get the corresponding external pressure.
    DMTY series strain earth pressure gauge is composed of support plate, induction plate, observation cable, strain gauge, etc. The smooth surface of the earth pressure box is the stressed surface, and the other side is the support surface
