The QCX-2M lifting limiter adopts 51 series microcontroller technology, digital circuit design, and the sensor part is the same. The instrument has functions such as automatic calibration, switching between gross and net weight display, zero point tracking, and accumulation and memory of overload times. Please refer to the commonly used instrument for the appearance diagram. The QCX-2W lifting weight limiter transmits sensor signals to the main instrument through wireless remote control.

The QCX-2M type lifting weight limiter instrument mainly adopts single-chip technology digital circuit, which has 2B type function, as well as automatic verification, gross net weight switching, zero point tracking, and overload accumulation memory function.

The QCX-2W lifting weight limiter instrument is an improved version of the 2M model, which enables wireless transmission of sensor signals to the instrument. The instrument is divided into two parts: the main instrument (receiving signal display and control) and the wireless transmitter.
