Latest company news about Features of Load Cells

Resistance, inductance, and capacitance are the three major types of passive components in electronic technology. Capacitive sensors convert changes in the measured quantity into variations in capacitance; essentially, they are capacitors with variable parameters.

 

Capacitive sensors have the following advantages:

(1) High impedance and low power consumption, requiring only minimal input energy.

(2) They can achieve large variation ranges, thereby offering high signal-to-noise ratio and system stability.

(3) Fast dynamic response, with operating frequencies reaching several megahertz, allowing for contactless measurement, and the target can be a conductor or semiconductor.

(4) Simple structure and strong adaptability, capable of operating in harsh environments such as extreme temperatures and intense radiation, with broad applications. With the development of electronic and computer technologies, the issues of susceptibility to interference and distributed capacitance that capacitive sensors face have been continuously overcome. Moreover, capacitive displacement sensors and integrated capacitive sensors have been developed. Therefore, they find widespread use in non-electrical measurement and automatic detection, capable of measuring parameters such as pressure, displacement, rotation speed, acceleration, temperature, thickness, liquid level, humidity, vibration, and composition content. Capacitive sensors have a promising future.
