Description :

　　Fujian Institute of Metrology Standard Force Gauge 2000kN 3000KN 5000kN Detailed Description: YOLO-LOADCELL, a brand of Youzhongli, produces weighing sensors and various weighing modules, which can be used for single item weighing, batching system weighing control, and can output communication and analog signal connection in the control system. It has high accuracy (0.05%~0.1%) and good stability (annual stability of 0.03%). Aluminum alloy material, alloy steel material, stainless steel material, explosion-proof type, etc. can be selected according to the on-site environment. Force sensor, used for various small space force measurement, large hydraulic equipment force measurement, tension and pressure calibration measurement, can be matched with various digital display instruments, tension and pressure controllers, standard force measuring instruments

　　Key maintenance points for weighing sensors

　　1. Some "baffles" should be set up around the weighing sensor as much as possible, and even thin metal plates should be used to cover the sensor. This can prevent impurities from contaminating the sensor and certain movable parts, which often cause discomfort in the movement of the movable parts and affect the weighing accuracy. The presence or absence of motion discomfort in the system can be determined using the following methods. Add or subtract approximately one thousandth of the rated load on the weighing platform to check if the weighing display reflects. If it does, it indicates that the movable part is not "contaminated".

　　2. Shielded cables should be used for wires leading to or from the display circuit. The connection and grounding points of shielded wires should be reasonable. If it is not grounded through the mechanical frame, it will be grounded externally, but if the shielding wires are connected to each other and not grounded, it will be floating. Note: There are 3 sensors that are fully connected in parallel. The sensors themselves are 4-wire, but they have been replaced with a 6-wire connection in the junction box. The sensor output signal readout circuit should not be placed in the same box as devices that can generate strong interference, such as controllable silicon and contactors, or devices that can generate considerable heat. If this cannot be guaranteed, it is necessary to consider setting up barriers to isolate them and installing fans inside the box. Electronic circuits used to measure sensor output signals should be equipped with independent power transformers as much as possible, rather than sharing the same main power supply with equipment such as contactors.

　　3. Sensors should use hinged copper wires (with a cross-sectional area of approximately 50mm2) to form an electrical bypass to protect them from the hazards caused by welding currents or lightning strikes. During the use of sensors, it is necessary to avoid strong thermal radiation, especially on one side.

　　4. In terms of electrical connections (such as signal cables for sensors, they should not be arranged in parallel with high-voltage power lines or control lines (for example, do not place sensor signal lines, high-voltage power lines, and control lines in the same pipeline). If they must be placed in parallel, the distance between them should be kept at least 50cm, and the signal lines should be covered with metal tubes.
