Parallel Beam Load Material
Hanzhong Quanyuan Electronic Co.,Ltd | Updated: Oct 13, 2017

Parallel beam sensor is one of the most commonly used sensors in the weighing sensor, widely used in electronic scale, kitchen scale, jewelry scale, and other areas of the industry, is indispensable to industrial and agricultural automation of core components, such as box shape appearance, collectively known as parallel beam weighing sensor in the industry.

Aluminum alloy material, colorless anodizing, sealant. The main application of electronic balance, weighing scale and other small table electronic scales

principle

Parallel beam sensors based on the principle that elastomer (elastic element, sensitive beam) elastic deformation under the action of external force, the resistance strain gauge on the surface of the paste in his (cell) also along with the deformation, deformation resistance strain gauge, its value will change (increase/decrease), and then through the corresponding measurement circuit convert the resistance to electrical signals (voltage or current), so as to complete the process of external force transform into electrical signals.

Considering the strategy use site acceleration and air buoyancy influence on conversion, performance of the parallel beam sensors mainly consists of linear error, hysteresis error, repeatability error and creep, zero temperature characteristic and temperature characteristic sensitivity, etc.

Parallel beam sensor has the advantage of high precision, wide measurement range, long life, simple structure, good frequency response characteristics, can work in harsh conditions, easy to realize miniaturization, integration, and species diversity, etc. Its disadvantages are that the large strain has a large nonlinear and weak output signal, but it can take certain compensation measures. Therefore, it is widely used in automatic test and control technology.

Installation method

First prepare two tablets, the material and the size according to need. According to the fixed hole of the sensor; Then prepare the four screws, the screwdriver, and the bottom pads. With the sensor as between the two boards, with the inner hexagonal screw, the plate and the parallel beam weighing sensor are fixed firmly. The top plate is fixed to the end of the sensor, and the other end of the plate is fixed. It is necessary to add a pre-prepared gasket to the sensor between the upper and lower plates, so that the sensor can be suspended. Finally, the installation of the sensor can be completed by fixing the foot and other parts.
