What industry does the sensor belong to?

Sensors are both sensitive components in the electronic component classification and industrial automation devices in the industrial automation classification.

Which majors are related to sensors?

Automation, electrical, telecommunications, communications, electronics, anything that has anything to do with it is related to this thing.

But there are some applications in industrial control, instrumentation, and other hardware fields.

What is a sensor professional course?

This course is offered to majors in sensor measurement and control engineering, and it is the most basic sensor technology. If you go deeper into your studies, this course will also be offered at the graduate level, covering modern sensor technology or many other miscellaneous topics. However, those who study this generally have majors in the direction of hardware measurement and control automation, and general measurement and control is a must-learn. Hope to adopt it

Which discipline is sensor?

Many majors have a sensor orientation, but there is no specialized major. For example, I am majoring in biomedical engineering. The sensor direction focuses on chemical and biological sensing, vehicle engineering, machinery manufacturing, and related sensing directions. It's just that the focus and background are different.

Which profession is involved in designing and manufacturing sensors? Is it also automated?

The automation major mainly cultivates system analysis, system design, and system operation in the fields of industrial process control, motion control, detection and automation instrumentation, power electronics technology, electronics and computer technology, information processing, management and decision-making, etc. , senior engineering and technical talents in scientific research and development. The detection and automated instruments inside should be related. In fact, there is no major to study this. It is all auxiliary learning

I want to study sensors in college. What major should I study?

1. The instrumentation major in the automatic control department of the university is intertwined with other majors and has the most knowledge about sensors.

2. However, original breakthroughs in sensors are often contributions made in the field of materials. If you really want to make a career, you might as well choose a major in functional materials in relevant universities while maintaining a strong understanding of circuit theory and Practical emphasis.

I wish you success!

What are the types of sensors? What properties or other attributes are used to distinguish them?

A sensor that converts the rotational speed of a rotating object into electrical power output. Speed ??sensors are indirect measurement devices that can be manufactured by mechanical, electrical, magnetic, optical and hybrid methods. According to different signal forms, speed sensors can be divided into two types: analog and digital. The output signal value of the former is a linear function of the rotational speed, and the output signal frequency of the latter is directly proportional to the rotational speed, or its signal peak interval is inversely proportional to the rotational speed. There are many types of speed sensors and they are widely used. The reason is that various motors are widely used in automatic control systems and automated instruments. In many cases, low speed (such as one revolution per hour or less) and high speed (such as tens of seconds per minute) are required. There are strict requirements for accurate measurement of steady speed (such as the error is only a few ten thousandths) and instantaneous speed. Commonly used speed sensors include photoelectric, capacitive, variable reluctance and tachometer generators.

Photoelectric speed sensor is divided into two types: projection type and reflection type. The reading plate and measuring plate of the projected photoelectric speed sensor have gaps at the same intervals. The measuring disk rotates with the object being measured. Every time it rotates through a gap, the light projected from the light source onto the photosensitive element (see photoelectric sensor) changes in light and dark, and the photosensitive element outputs a current pulse signal (Figure 1). The reflective photoelectric sensor is equipped with a reflection mark on the measured rotating shaft, and the light emitted by the light source is incident on the measured rotating shaft through the lens and semi-transparent film. When the rotating shaft rotates, the reflectivity of the reflected mark to the projected light spot changes. When the reflectivity becomes larger, the reflected light is projected onto the photosensitive element through the lens and a pulse signal is emitted; when the reflectivity becomes smaller, the photosensitive element has no signal. The rotational speed value of the rotating shaft can be measured by counting the signals within a certain period of time (Figure 2).

Variable reluctance speed sensor It is a variable reluctance sensor.

The three basic types of variable reluctance sensors, inductive sensors, transformer sensors and eddy current sensors can all be made into speed sensors. Inductive speed sensors are widely used. They use changes in magnetic flux to generate induced electric potential, and the size of the electric potential depends on the rate of change of magnetic flux. This type of sensor is divided into open magnetic circuit type and closed magnetic circuit type according to different structures. The open magnetic circuit speed sensor (Figure 4a) has a relatively simple structure and a small output signal, so it is not suitable for use in situations with severe vibration. The closed magnetic circuit speed sensor consists of an external gear, an internal gear, a coil and a permanent magnet mounted on the rotating shaft (Figure 4b). The inner and outer gears have the same number of teeth. When the rotating shaft is connected to the measured shaft and rotates together, the reluctance changes due to the relative movement of the inner and outer gears, and an AC induced electric potential is generated in the coil. By measuring the magnitude of the potential, the corresponding rotational speed value can be measured.

Which category of trademark class 45 does the sensor belong to?

The sensor is a product in Part (4) of the similar group 0913

What third-level discipline does wireless sensor routing belong to?

Third-level science of engineering technology.

A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the needs of the information. Requirements for transmission, processing, storage, display, recording and control.

The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systematization and networking. It is the primary link to realize automatic detection and automatic control. The existence and development of sensors give objects senses such as touch, taste, and smell, making objects slowly become alive. It is usually divided into ten categories according to its basic sensing functions: heat sensor, light sensor, gas sensor, force sensor, magnetic sensor, humidity sensor, sound sensor, radiation sensor, color sensor and taste sensor. .

What type of sensor does the proximity switch belong to?

Proximity switches are non-contact sensors. They are generally divided into: photoelectric, electromagnetic, and capacitive. This can be selected according to your installation environment and control circuit requirements.
