Sensing technology is mainly based on the study of the principle of sensing face, the material of sensor, the design of sensing goose, the production of sensor and the application of sensor answer. The principle and application method of various types of sensors are the points of the textbook, which will be described in detail in the second core. This article will briefly introduce the basic characteristics of the sensor, the material of the sensor, the manufacturing technology of the sensor, the design method of the sensor, and the information processing of the sensor application circuit system.
The sensor usually consists of a scanning element and a sensing element. The sensory element is directly dependent on the side of the non-electrical t, and is converted into an element that is in a defined relationship with the side basin, which is generally a non-electrical basin. For example, the diaphragm and the bellows are converted into displacement by the side pressure and the like. The sensing element, also known as the transducer, is a component that can directly convert the non-electrical t that is sensitive to the sensitive component into the desired signal, which is generally the most probable. For example, the elastic diaphragm in the strain gauge pressure transmitter is sensitive. The component, and the strain gauge is the sensing component.
The sensitive component and the sensing component can also be combined into one, which is called a primary sensing component, which can directly output electricity t. Such as piezoelectric crystals, thermoelectric power supply, thermal limit, optical devices, they directly feel the measured t and find the electrical double with a certain relationship. Some types of integrated circuit sensors also integrate sensitive components, sensing components, and signal processing circuitry into one device.
The basic characteristics of the sensor generally refer to the sensor's ingestion and output characteristics, which are divided into dynamic and dynamic.
