QCX series bearing seat sensor is mainly installed under the bearing seat, can also be used in other structural forms, is the main measurement of a bearing seat bearing capacity of the special sensor sensor.  The principle of structure is shear resistance strain sensor which is supported by the center at both ends.  High quality alloy steel is used as elastomer and foil resistance strain gauge is used as sensitive switching element.  The bearing seat is installed in the middle of the sensor, and the two ends of the sensor are fixed on the base.  When the bearing seat is loaded, the load is transferred to the base through the shear elastic beam at both ends, and the strain proportional to the load is generated in the elastic beam, which is converted into the corresponding electrical signal through the strain gauge.  Suitable for lifting, water conservancy and other industries under the bearing seat tension testing and control system.
