The weighing sensor is a sensor device that measures the force of the object by examining the load of the force support, the weighing sensor can convert the pressure from the carrier into a corresponding electrical signal, thereby achieving the purpose of the measurement, and the weighing sensor is The quality signal is converted to a device that can be measured.

Before installing the weighing sensor, you should first consider the actual working environment of the load cell, which is very important to select the correct installation load cell, the use environment of the load cell and the load cell is normal, life and reliability And safety is related, the weighing sensor is divided into 8 types of types according to the conversion method: photoelectric, hydraulic, electromagnetic, capacitance, magnetic pole variation, vibration type, gyroscope, resistance strain type, etc.

There is a difference in the quality of the technical indicators and national standards between the basic concepts and evaluation methods, such as S-type weighing sensors, cantilever weighing sensors, spoke weighing sensors, board ring weighing sensors, Corrugated tube weighing sensor, bridge type weighing sensor, column weighing sensor, etc.

The working principle of the weighing sensor is to stretch the metal resistance wire under the tension, then the resistance increases, that is, the metal resistance varies with the strain to be subjected, and the weighing sensor is used to convert the weight signal or pressure signal to the electric quantity.  The signal conversion device, the constructor of the weighing sensor is that the metal resistance has the characteristics that hinder current flow. In general, the finer the metal wire, the larger the resistance value, and when the metal resistance line is expanded under external force, the resistance value is  It will increase or decrease within a certain range, and therefore, if the metal wire (or film) is tightly adhered to the measured matter, the metal resistance line will be proportionally telescope.  The resistance value changes the corresponding changes, and the weighing sensor pastes the metal resistance strain gauge on the metal weighing beam to measure the weight signal.

The elastomer of the weighing sensor is a structure of a special shape. It has two functions, first and the external force of the weighing sensor, and produces a reaction force to the external force to achieve relative static balance, secondly, the elastomer of the weighing sensor can be Generating a high-quality strain field (region) to adhere to the region, the elastomer of the weighing sensor is ideal for completing the strain signal conversion task, the above is all the contents of this article, thank you for watching, you have to know more Please pay attention to us, goodbye!
