Parallel Beam Load Cell Installation Method
Edit: Hanzhong Quanyuan Electronic Co.,Ltd    Date: Apr 13, 2016

Parallel beam sensor is one of the most commonly used sensors in the load cell, it is widely used in electronic scale, kitchen scale, jewelry scale and other industries.Industrial and agricultural automation system is an indispensable core components, shape, such as quadrilateral shape, industry Internal collectively referred to as parallel beam load cells.


Using aluminum alloy material, colorless anodized, sealant,it is mainly applicable to electronic price scale, weight scale and other small table electronic scales:

Principle: The parallel beam sensor is based on the principle that the elastomer (elastic element, sensitive beam) is elastically deformed under external forces so that the resistance strain gauge (switching element) pasted on his surface is deformed and the resistance strain gauge is deformed , Its resistance will change (increase or decrease), and then the corresponding measurement circuit to convert this resistance into electrical signals (voltage or current), thus completing the external force into the process of electrical signals.

Considering the influence of the strategy acceleration and the air buoyancy on the conversion, the performance index of the parallel beam sensor mainly includes linearity error, hysteresis error, repeatability error, creep, zero temperature characteristic and sensitivity temperature characteristic.

Parallel beam sensor has the advantages of high precision, wide measurement range, long life, simple structure, good frequency response characteristics, can work in harsh conditions, easy to achieve miniaturization, integration and variety diversity. Its shortcomings are for large strain has a large non-linear, the output signal is weak, but can take some compensation measures. So it is widely used in automatic test and control technology.

Installation method: first prepare two flat, material and size according to the need to set. Hold the eye in accordance with the sensor's retaining hole; prepare the four screws, the screw cap, and the lower pad. The sensor as between the two plates, with hexagonal screws and the parallel beam beam sensor fixed fixed. The upper plate fixes one end of the sensor, and the lower plate fixes the other end of the sensor. Fixed when the upper and lower plate and the sensor should be added between the pre-prepared gasket, so as to be able to make the sensor hanging force. Finally, the pad and other components are fixed to complete the sensor installation.
