"Quickly get on the scale, let me see how much you weigh! "In daily life, this is the moment when we have the closest contact with a weighing sensor. Taking a household weighing scale as an example, the editor will introduce the working principle of a weighing sensor to everyone-
When a person stands on a weighing scale, pressure is generated, causing the surface to deform and triggering a change in the shape of the built-in resistor. The deformation of the resistor causes a change in its resistance value, which is then processed by an integrated circuit and causes a change in the internal current, resulting in the generation of corresponding electrical signals.
Different pressures correspond to different current sizes, and this electrical signal becomes a weight visible number after processing. From this, we can know what our weight is
Less.
In fact, not only household weighing scales, but also weighing sensors have a wide range of applications, including but not limited to the following aspects
1.Industrial production: used for automated weighing, batching, etc. on production lines to determine the stability of product quality.
2.Logistics transportation: used for weighing and billing of goods, providing data support for the accounting of logistics costs. three
3.Commercial commission sales: Electronic scales used in supermarkets, agricultural markets, etc., providing convenient weighing services for sellers. four
4.Medical Health: Used for weight monitoring in medical devices, etc., to provide better medical services for patients.
5.Scientific research: used to measure sample weight in laboratories, providing accurate data for experiments and studies.
In different fields, the type of weighing sensor used varies. Generally speaking, how should we choose the appropriate weighing sensor? What are the precautions?
Classification and Application of Weighing Sensors
S-type weighing sensor
It is mainly used for weighing feed and ingredients, with the advantages of easy installation, stability and reliability, and is generally used in sample stations.
The bridge type weighing sensor
It is more complex than the S-type, mainly due to the lack of structural design. The bridge type is a double shear structure design, mainly suitable for electronic weighing equipment such as car scales, spreading scales, axle scales, overhead crane scales, etc.
The cantilever beam type weighing sensor
It is mainly used in monorail weighing, and its structure is a cantilever shear structure. Its advantages are easy to use and high accuracy.
Column type weighing sensor
A compression type weighing sensor, whose deformable part is cylindrical and will shorten under load: this allows the weighing sensor to withstand high loads while maintaining a limited diameter. Generally installed on a weighing scale or large mileage silo, each group should have at least 4 parallel weighing sensors.
Spoke type weighing sensor
Adopting a fully sealed welding technique, it provides good protection against water, oil, and even harmful gases. It can be used as a standard sensor and is mainly suitable for tension and pressure testing instruments such as universal material testing machines, hopper scales, hook scales, belt scales, as well as automation equipment and testing fields.
matters needing attention
1. Regular inspection and maintenance: Regularly inspect the weight sensor, including its appearance, cables, connectors, and other components, to ensure that it is intact and undamaged. For problems discovered, timely repair or replacement should be carried out.
2. Environmental improvement: Optimize the working environment, reduce the impact of temperature, humidity, and electromagnetic interference on sensors. For example, adding ventilation facilities, using anti-interference cables, etc.
3. Reasonable operation: During installation and use, the operating procedures should be followed to avoid mechanical damage and overload.
4. Power management: Regularly check the power circuit to ensure stable and reliable power supply. For situations with significant power fluctuations, it is recommended to consider using a regulated power supply or UPS equipment.
5. Correct selection: Choose the appropriate weighing sensor according to the actual application scenario to ensure that the sensor can meet the requirements of accuracy, range, etc.
