Limin sensor has great potential in the consumer electronics industry
Force sensors are sensors used to detect interactions between gases, solids, liquids, and the like. Common materials are semiconductors, metals and synthetic materials. Currently commonly used are silicon piezoresistive force sensors and capacitive force sensors. The advantages of the silicon pressure sensor are that the sensitivity is high, the precision is high, and the disadvantage is that it is greatly affected by temperature.
The force sensor is mainly used in the equipment manufacturing industry, such as industrial automation systems, mechatronics, scientific test instruments, etc. It mainly involves the detection, control and execution of two major parameters of pressure and flow for process control.
Household appliances and consumer electronics
The household appliances and consumer electronics industries are developing in the direction of automation, intelligence, energy saving and pollution-free. They require force-sensitive components and sensors to be in line with this direction. The center of automation and intelligence is to develop a control system consisting of sensors and microcomputers. For example, an air conditioner with a microcomputer and sensor technology can realize the control system of starting, stopping, and fan reversing of the compressor.
The application of silicon-based force-sensitive element and force sensor usually involves pressure measurement, differential pressure measurement, liquid level measurement, etc. The measurement amplification circuit involved in the relevant application is as follows: in-phase series differential operation amplification circuit, in-phase parallel differential operation amplification circuit, The instrument uses an amplifying circuit, an amplitude modulation circuit, a frequency modulation circuit, and the like.
