What do you know about electronic crane scales?
 The electronic crane scale is refers to the collection program control, the group control, the telex printing record, the screen flash and so on modern electronic crane technology's supporting application, will cause the weighing implement function to be complete, the power is higher. Measuring equipment using the principle of radioactivity and the principle of hydraulic transmission ratio will have limited opening. In the contact between weighing and production process, the instrument connected with the electronic crane hook scale will play a corresponding role in saving manpower and material resources, and its application plan will be further expanded. With its root measurement function, the commercial value and reliability requirements of the scale will gradually increase. When measuring goods with high value, the measurement accuracy is required to be high; Measure the value of lower goods, then the primary consideration of measurement power. This will promote the weighing apparatus to diversify, multi-level direction open.
 Electronic crane scale is mainly composed of three parts: sensor, scale frame and weighing display master. Scale frame is the load acceptance and transmission installation of transferring the weight of the items on the belt to the weighing sensor. The accuracy and stability of a certain link plays a decisive role in the function of the electronic crane transmission belt scale.
 Secondly, we need to know the weighing principle of electronic crane scale.
 Fx→  sensor →OP expansion →A/D conversion →CPU→ flash driver
 People in different places can see all kinds of weighing facilities, is commonly known as the scale. It is also based on the principle of lever. The lever is installed on the upper part of the transmission belt that is in continuous operation, and the bearing surface of the lever is how many buoys are installed to satisfy the requirement that the transmission belt is flowing through the period below to reduce the weighing error caused by the friction between the transmission belt and the bearing surface. Simultaneous show up for Numbers signal to stop the internal artificial control, make weighing electronic crane belt scale according to the practical request of the feed rate of active change speed transmission belt's progress, for a given feed rate of stop tracking, which constitute a belt feeding time, progress is slow, small progress faster, without the fastest progress, when the overload when the slowest characteristics that will stop up.
 Finally, let's take a look at the electronic crane scale operation process.
 When the object is suspended on the electronic crane hook scale, the pressure is applied to the sensor, and the sensor deforms, so that the impedance changes, together with the use of induced voltage changes, output an analog signal. The signal is amplified by an expansion circuit to an analog-to-digital converter (A/DF), which converts the signal into an easily processed digital signal for CPU operation and control. The CPU outputs this effect to the meter according to keyboard instructions and programs, and then the meter displays the weighing  quantity, records and prints it. It can also be connected to the weighing management system, and the weighing quantity can be counted by the computer.
 Professional terms of electronic crane scale:
 1.  Maximum weighing: an electronic crane scale does not count tare weight, and the maximum weighing capacity (full load value) is the maximum load that can be weighed;
 2.  Minimum weight: a relative error of an electronic crane scale when it is lower than the value;
 3.  Safety load: 120% normal weighing range;
 4.  Rated load: normal weighing range;
 5.  Allowable error: the maximum allowable deviation during grading verification;
 6.  Sensitivity: the minimum scale displayed by an electronic crane scale; It's usually denoted by a "d".
