Electronic crane scale through the load loading hook action on the sensor, so that the explosion-proof sensor elastomer undergoes a small change, the explosion-proof sensor is converted into the corresponding analog voltage signal transmitted to the data acquisition board, through the amplification, filtering, A/D converted into the corresponding digital signals, through the wireless transmission system to the instrumentation of the data processing board to obtain the corresponding weight data.

Electronic crane scales are mainly used as the core chip to measure the force, the main part of the force measurement principle for hook scales are bent elastic steel, deformation of the load cell and the scale body is an integrated unit, the weighing scale unit is hung on the hook of the lifting machinery, powered by rechargeable batteries; the display unit is placed on the ground on the operating platform, the operating platform can be 100-400m away from the site of the crane. The operating platform is located on the ground at a distance of 100-400 m from the site of the lifting machine, and the electrical signals of the weight are transmitted in the form of coded carrier waves through the radio transmission device on the weighing unit, and the receiving device on the weighing controller unit accepts the signals and sends them to the microprocessor for processing, and then finally displays the mass of the object to be weighed or prints out a record.

High-temperature electronic crane scales utilize the load cell of the thermal state ring to adapt to high temperatures above 1,000 degrees Celsius, and there will be a high-temperature heat insulation board under the crane scale instrument, and the heat insulation board is a prerequisite for high-temperature resistance. Thermal insulation material is added to the casing of the scale. This isolates all the remaining heat through the insulation board. This ensures that the high-temperature-resistant hook scales work at temperatures of up to 1800 degrees Celsius.

Electronic crane scale's hanging ring hangs on the crane's hook, when the electronic crane scale's hook hangs on the item, the sensor in the scale body is deformed by the tension, and the current inside the sensor changes, and then this change of current is converted by the A/D, and then through the transmitter to send out the radio signals, according to the regulations of the State Radio Regulatory Commission, the electronic crane scale is generally used 230MHZ and 450MHZ. According to the regulations of the State Radio Management Committee, the electronic crane scale is generally used 230MHZ and 450MHZ to send out, and the receiver receives the signal and transmits it to the meter, and then it is converted and calculated by the meter and finally displayed.

The electronic crane scale is composed of load cell amplification circuit, AD conversion circuit, microcontroller circuit, display circuit, keyboard circuit, communication interface circuit, voltage stabilized power supply circuit and other circuits. The weight of the object through the hook on the sensor, the sensor is converted into a corresponding analog voltage signal sent to the data acquisition board through amplification, filtering, A/D into a corresponding digital signal, and then processed by the instrument's data processing board to obtain the corresponding weight data, by the display to show the number of the display is directly embedded in the crane scales on the scale body.

Wireless electronic crane scale is a relatively advanced crane scale which transmits the weighing data to the ground display by radio, which greatly facilitates the use of electronic crane scale, and at the same time, it can easily print, store, and transmit the weighing results to the computer or big screen. It mainly includes wireless instrument, upper hanging ring, lower hook, receiving and transmitting protective seat, receiving and transmitting device, AD box, AD converter, sensor, antenna, battery and other main components. It fundamentally realizes the separation of weighing body and display, and transmits the data after weighing body load bearing to the display through radio, which is convenient for printing and storing data.

The wireless crane scale is the ideal measuring instrument for weighing suspended goods, with LED display, all-steel construction shell, good anti-electromagnetic interference performance, and can be used directly on electromagnetic suction cups. Excellent dynamic performance, even under strong shaking can quickly obtain stable and accurate weighing results.

The electronic crane scale allows the operator to obtain a series of data such as gross weight, net weight, tare weight and totalized address of the material from the display of the receiving instrument or from the printer when the operator is far away from the weighing site, and the instrument together with the printer facilitates real-time recording and printing of the data. The functions of automatic/manual printing, zero tracking and system calibration can be realized through the keyboard and the function switches on the receiving instrument, making it very easy to operate and use.

Explosion-proof crane scales are electronic scales for measuring the mass (weight) of an object in a suspended state. The scale body, load cell and weight indicator form a whole, and use intrinsically safe batteries, sensors, instruments or explosion-proof instruments to form a direct-view crane scale with intrinsic safety or explosion-proof functions.
