　　500kg single point sensor packaging scale weighing sensor 300kg Youzhongli sensor manufacturer detailed instructions:

　　A weighing sensor is actually a device that converts a mass signal into a measurable electrical signal output. The first thing to consider when using sensors is the actual working environment in which the sensor is located. This is crucial for selecting sensors correctly, as it relates to whether the sensor can work properly, its safety and service life, and even the reliability and safety of the entire weighing apparatus. In general, high temperature environments cause problems such as melting of coating materials, cracking of solder joints, and structural changes in the stress inside the elastomer for sensors; Dust and moisture can cause short circuits in sensors; In highly corrosive environments, it can cause damage to the elastic body of the sensor or result in short circuits; Electromagnetic fields can interfere with sensor outputs. We must choose the corresponding weighing sensor to meet the necessary weighing requirements under the corresponding environmental factors.

　　Accuracy level selection

　　The accuracy level of weighing sensors includes technical indicators such as nonlinearity, creep, repeatability, hysteresis, sensitivity, etc.

　　Application scope and purpose

　　For example, aluminum alloy cantilever beam sensors are suitable for electronic pricing scales, platform scales, cutting scales, etc; Steel cantilever beam sensors are suitable for electronic belt scales, sorting scales, etc; Steel bridge sensors are suitable for railway scales, truck scales, etc; Column sensors are suitable for car scales, dynamic track scales, large tonnage hopper scales, etc. Weighing sensors are mainly used in various electronic scales, industrial control fields, online control, safety overload alarm, material testing machines, and other fields. Such as electronic car scales, electronic platform scales, electronic forklifts, dynamic axle scales, electronic hook scales, electronic pricing scales, electronic steel scales, electronic track scales, hopper scales, ingredient scales, canning scales, etc.

　　Wiring method

　　There are two types of wiring for weighing sensors: 4-wire and 6-wire. There are also two types of wiring for modules or weighing transmitters: 4-wire and 6-wire. Whether to connect 4-wire or 6-wire depends on your hardware requirements. The principle is that sensors that can be connected to 6-wire should not be connected to 4-wire, and those that must be connected to 4-wire should be short circuited.

　　Generally, weighing sensors are six wire systems. When connected to a four wire system, the power lines (EXC -, EXC+) and feedback lines (SEN -, SEN+) are respectively short circuited. SEN+and SEN - are used to compensate for circuit resistance. SEN+and EXC+are pathways, while SEN - and EXC - are pathways.

　　EXC+and EXC - are used to power the weighing sensor, but due to circuit losses between the weighing module and the sensor, the voltage received by the sensor will actually be lower than the supply voltage. Each weighing sensor has a characteristic of mV/V, and the mV signal it outputs is closely related to the received voltage. SENS+and SENS - are actually high impedance circuits inside the weighing sensor, which can feedback the actual voltage received by the weighing module to the weighing module. Assuming EXC+and EXC - are 10V, with a line loss of 2mV/V for the sensor, in reality, the maximum output signal of the sensor is () * 2=19mV instead of 20mV. At this point, the internal weighing sensor will consider 19mV as the maximum range, provided that the sensor must feedback the actual voltage to the weighing module through a feedback loop. Short circuit EXC+to SENS+and EXC - to SENS - on the weighing sensor is only suitable for situations where the sensor is close to the weighing module and the voltage loss is very small, otherwise there may be measurement errors.

　　YOLO-LOADCELL, a brand of Youzhongli, produces weighing sensors and various weighing modules that can be used for single item weighing, ingredient system weighing control, and can output communication and analog signal connection control systems. 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 displays, tension and pressure controllers, and standard force measuring instruments.
