Anti-biting signal cable

The anti-chewing weighing sensor signal cable of Weight Worth is a type of cable specifically designed to prevent rodents from chewing.

1.Structural Design:
(1.)Multi-layer Protection: Generally consists of TPU layer, PVC layer, rat-proof layer, insulation layer and wire core. The rat-proof layer is formed by the intersection of multiple soft metal wires, with a thickness ranging from 0.8mm to 1mm. This structure can effectively resist the gnawing of rats.
(2.)Metal Shell: Some signal lines are wrapped with a metal shell. For example, the external part of the Vittorovas scale line has a metal shell, which can play a good role in preventing rat bites.

2.Material characteristics:
(1.)Adding chemical substances: Some signal lines are treated with special chemical additives. These additives cause the cables to emit unpleasant odors and tastes that rodents find repulsive, thereby preventing them from gnawing.
(2.)Malleable polymer core: Made with a malleable polymer core, it enhances the strength and durability of the cables. Not only can it resist rodents' gnawing, but it can also withstand certain mechanical wear and trampling.

3.Advantages and features:

(1.)Strong anti-chewing ability: Through special structural design and material selection, it can effectively prevent chewing by rodents such as rats, reducing problems with abnormal weighing data transmission caused by damaged cables, and lowering maintenance and replacement costs.
(2.)High durability: With wear-resistant polymer core and multi-layer protective structure, it has good wear resistance and tensile strength, capable of withstanding certain external forces and environmental erosion, and has a long service life.
(3.)Stable signal transmission: With excellent electrical performance and anti-interference ability, it can ensure the accurate and stable transmission of weighing signals, guaranteeing the reliability of the weighing system.
(4.)Application scenarios: Mainly used in various weighing equipment such as electronic floor scales, belt scales, packaging scales, etc. Especially in environments prone to rodent infestation, such as warehouses, farms, and livestock farms, it can effectively ensure the normal operation of the weighing system.

1. Stainless Steel Material: Excellent corrosion resistance and structural stability, suitable for complex medium environments
Stainless steel (commonly in types such as 304 and 316L) is the core material foundation of this type of sensor. Its advantages directly address the key pain point of "environmental erosion":
(1.)Strong corrosion resistance, suitable for various media scenarios
Most sensors use carbon steel as the material, which is prone to corrosion by water, oil, chemical reagents (such as acid-base solutions, pesticides, industrial cleaning agents), leading to rust on the structure and failure of the strain gauge; while stainless steel (especially 316L) contains alloy elements such as chromium, nickel, and molybdenum, which can form a stable oxide film on the surface, capable of withstanding:
Ⅰ.Wet environments (such as fishery processing workshops, water accumulation in slaughterhouses, high humidity);
Ⅱ.Corrosive media (such as acid-base fumes in chemical workshops, disinfectants in livestock farms, salt water / soy sauce in food processing);
Ⅲ.Outdoor rain and snow, coastal salt fog (such as weighing platforms at port docks, outdoor material tank weighing), avoiding material rusting that leads to accuracy decline or structural fracture.
 (usually 2-3 times longer than ordinary carbon steel sensors).

IP68 sealing grade: "Fully dust-proof + Deep water-proof", completely preventing all foreign objects from entering
1.Dust-proof grade IP6X: Completely prevent dust, avoiding blockage of internal components
Achieving IP6X means that the sensor housing can completely prevent any dust from entering the interior (including fine sand, cement dust, industrial dust, etc.). Ordinary sensors (such as IP65) can prevent large particles of dust, but fine dust is prone to enter the strain gauge area through gaps, resulting in:
Dust accumulation at the interface between the strain gauge and the elastic material, affecting deformation conduction and causing accuracy deviation;
Internal circuit contacts are covered by dust, causing poor contact and signal interruption.
The sealing structure of IP68 (such as welding sealing + double protection with sealing rings) can completely isolate dust and is suitable for "high dust environments".
2.Waterproof grade IP68: Deep immersion does not get water, suitable for underwater / high humidity scenarios
The waterproof standard of IP69k is "Long-term immersion at the specified pressure (usually ≥ 1m water depth) without getting water", far exceeding the protection capability of ordinary IP67 (short-term immersion), and can cope with:
Short-term immersion scenarios (such as workshop water accumulation over the sensor, outdoor heavy rain causing weighing platform water accumulation);
Frequent rinsing scenarios (such as high-pressure water gun cleaning of food processing equipment, disinfection rinsing of livestock farms);
Water-level weighing scenarios: Avoid internal circuit short circuits and strain gauge moisture failure (this is the core reason for "high failure rate" of ordinary sensors in humid environments).

FAQ

What is the working principle of the cantilever beam load cell?

The cantilever beam weighing sensor operates based on the principle of strain gauges. When an object is placed on the sensor, the cantilever beam will undergo a slight deformation, and the strain gauges attached to the cantilever beam will also deform accordingly, resulting in a change in their resistance values. By measuring the change in the resistance values of the strain gauges and converting them into corresponding voltage or current signals through the signal conditioning circuit, the final weight value of the object can be obtained.

What is the measurement range of this cantilever beam load cell?

The range of different types of stainless steel IP68 cantilever beam load cells varies. Common ranges include 10kg, 20kg, 30kg, 50kg, 100kg, 200kg, 350kg, and 500kg. Some models can also reach larger ranges, such as 1134kg, 2268kg, and 4536kg.

Compared with other types of load cells, what are the characteristics of cantilever beam load cells?

The cantilever beam weighing sensor features simple installation, quick operation and convenient maintenance, which can save downtime for maintenance. It also has the capabilities of resisting overload, fatigue and unbalanced load, and can withstand both tension and compression working modes. Moreover, it has a small self-weight and is suitable for the weighing control of large-tonnage tankers during the batching process in harsh environments.
