[0007] Preferably, the installation claw includes installation claw 1, installation claw 2, installation claw 3 and installation claw 4.

[0008] Preferably, the installation claw 1, installation claw 2, installation claw 3 and installation claw 4 can be circular or square.

[0009] Preferably, the outer side of installation claw 2 and installation claw 3 is installed with the strain gage, the cable is arranged in the shell, one end of the cable is arranged on the outer wall of the shell, the other end of the cable is connected with the strain gage, and the strain gage is filled in the glue pouring cavity through the silicon gel.

[0010] Preferably, the cable is a wire wrapped cable.

[0011] Preferably, the shell is also silk-screened with a product model.

[0012] Compared with the prior art, the novel elevator weighing sensor has the advantages and positive effects that,

[0013] In the utility model, in use, the sensor is embedded in the steel belt, the steel belt passes through the four installation claws of the sensor, no fastener is needed, the installation efficiency is high, the structure is simple, the installation is convenient, can be installed on the steel belt and cooperate with the weighing control instrument to monitor the elevator weighing condition, compared with the conventional situation that no related sensor is arranged for the steel belt elevator, the overall structure of the sensor designed in the utility model is simple, the staff is convenient to install and maintain, no fastener is needed in the installation process, the steel belt directly passes through the installation claw, the overall structure is compact, the staff is easy to install and maintain, the structure is compact, the problem that most of the current sensors can only be applied to the elevator using the steel wire rope, the installation is difficult, and no easy-to-install weighing sensor is designed for the elevator using the steel belt is solved.
