working principle

The working principle of an electronic hanging scale is composed of electronic components such as weighing sensors, amplification circuits, AD conversion circuits, microcontroller circuits, display circuits, keyboard circuits, communication interface circuits, and voltage regulation power supply circuits.

Working principle of wireless suspension scale

The weight of the object is applied to the sensor through the hook, which converts it into a corresponding analog voltage signal and transmits it to the data acquisition board. After amplification, filtering, and A/D conversion, it is converted into a corresponding digital signal and sent to the data processing board of the instrument through a wireless transmission system for processing. The corresponding weight data is obtained and displayed on the instrument display screen. The weight data can be output through a serial port and printed by a printer, displayed on a large screen, or sent to the upper computer when needed.

Working principle of direct view suspension scale

The weight of the object is applied to the sensor through the hook, which converts it into a corresponding analog voltage signal and sends it to the data acquisition board. After amplification, filtering, and A/D conversion, it is converted into a corresponding digital signal, and then processed by the data processing board of the instrument to obtain the corresponding weight data. The digital data is displayed on the display screen, which is directly embedded in the suspension scale body. The operator can directly view weight data and other related information from the display window of the scale body.

Workflow Description

When an object is hung on the hook of a tension gauge, pressure is applied to the sensor, which deforms, causing a change in impedance. At the same time, the excitation voltage changes and outputs a changing analog signal. The signal is amplified by an amplification circuit and output to an analog-to-digital converter. Convert it into a digital signal that is easy to process and output it to the CPU for operation and control. The CPU outputs this result to the display based on keyboard commands and programs. Until this result is displayed.

Correct usage

(1) Before using the electronic hanging scale, the corresponding battery should be installed into the scale body and handheld device

When installing or replacing the battery, it is necessary to tighten the locking screw of the battery clamp, check whether the battery clamp is firmly fixed on the scale body, and then close and lock the hanging scale door to prevent accidents. When the instrument displays undervoltage, the battery pack should be replaced immediately and the replaced battery should be charged in a timely manner to prevent battery damage. When the battery pack is not used for a long time, it should be charged at regular intervals. The battery should be stored in a dry, ventilated, and suitable temperature environment, and avoid contact with corrosive substances. When loading and unloading the battery pack connection wire aviation socket, do not hold the wire clamp cap that clamps the wire with your hands, but should hold the base tightly. When connecting the power supply on the other side of the transmitter to the aviation plug, do not hold the wire clamp cap. Instead, hold the rotatable cap on the head for loading and unloading to prevent loose power connections and faults. Before connecting the transmitting device to the power supply, the antenna and its feeder must be reliably connected, otherwise the transmitting device will be damaged.

(2) Prevent the electronic suspension scale from being subjected to severe pulling and collision

There are many electronic components inside the electronic suspension scale, such as integrated circuits, quartz crystals, sensors, displays, etc. When the electronic suspension scale is subjected to severe collisions, these components may be damaged, causing the scale to malfunction, affecting accuracy and normal use. It is necessary to avoid collisions between the scale body and other objects or falling from a high altitude. The instrument should be handled gently and not placed randomly to prevent unnecessary losses. When the instrument is fixed on the crane for use, vibration reduction measures should be taken to avoid affecting reliability.

(3) Do not dismantle the components on the electronic hanging scale at will

When using the electronic suspension scale normally, do not disassemble the components on the scale at will, and do not open the sealing port on the sensor or disassemble the integrated circuit and other components on the instrument. Necessary repairs must be carried out under the guidance of relevant technical personnel or with certain maintenance knowledge to prevent the fault from expanding.

(4) The shell of the electronic hanging scale is made of ABS engineering plastic. When cleaning, please use a soft cloth with water or detergent to wipe it. It is strictly prohibited to use corrosive substances such as benzene, nitro solvents, and caustic soda liquids for cleaning.
