Skip scale of two-channel weighing

The utility model relates to a dual channel weighing skip scale, belonging to a weighing device. The weighing device makes use of two weighing devices to conduct skip weighing and automatically cuts out defective channels. The utility model is primarily to eliminate technological difficulty of prior skip scales, such as low serviceability and low accuracy of measuring of weighing systems. The technical proposal of the utility model is the dual channel weighing skip scale comprising a base, a head sheave bearing block and two weighing sensors, and a weighing and a defective channel cut out electronic system consisting of an amplifier, an analog-to-digital conversion circuit, a computation recognizer and peripheral equipment. The two weighing sensors are arranged on the left base and the right base and on the bottom surface of the head sheave bearing block and are permanently connected with the head sheave bearing block. An output port of each of the weighing sensors is connected with an input end of the amplifier on the same side; and an independent weighing signal is accordingly formed, which will goes into the computation recognizer through the amplifier and the analog-to-digital conversion circuit.
