Since its establishment, Hongbaoshi (Sanhe) Technology Co., Ltd. has established a perfect research and development, production, sales and service integration of modern management system. Focus on technology, pay attention to innovation, and constantly improve the technical level of products and service quality. With precise products, precise service, precise market as the core, and domestic machinery, shipbuilding, electric power, petroleum, railway, automobile and other industries of users to establish a long-term stable relationship of cooperation.

Our company according to the market demand design and development - pressure, temperature, temperature and humidity, speed, liquid level and other series of sensors and intelligent automation instruments, but also according to the specific requirements of users to design unique sensors, to meet the special environmental needs of users, and provide users with after-sales service.

Sensor is according to the material characteristics and laws of physics, chemistry, biology, designed the device, phyletic and various, usually based on its basic awareness into thermal sensor, light sensor, gas sensor, force sensor, magnetic sensor, moisture sensor, acoustic sensor, radiation sensitive element, color sensor and sensor etc. 10 major categories.

In the field of measurement and control, a sensor designed by a certain principle can measure a variety of non-electric quantity at the same time, and sometimes a kind of non-electric quantity can be measured by a variety of sensors with different principles, so there are many classification methods of sensors, generally classified according to the following methods.

Classification by use

According to the input can be divided into pressure, displacement, velocity, temperature, humidity and other sensors.

This classification clearly expresses the use of sensors, but it is not easy to find out the similarities and differences of the conversion principles of each sensor.

According to the principle of measurement

This classification method is based on the principles, laws and effects of physics and chemistry, which can be divided into physical sensors, chemical sensors and biological sensors. Such as voltage type, thermoelectric type, resistance type, photoelectric type, inductance type and so on.

The advantage is that the working principle of the sensor is relatively clear, less categories, which is conducive to the in-depth analysis and research of the sensor.

According to semiconductor related theory classification

It is divided into semiconductor force sensitive, heat sensitive, light sensitive, gas sensitive and other solid state sensors.

Classification by manufacturing process

It can be divided into integrated sensor, film sensor, thickness sensor and ceramic sensor.

Categorize by output

According to the output, there are switch, analog and digital sensors. The output signal of analog sensor is analog quantity; The output signal of digital sensor is digital quantity, which is easy to be used with computer and has strong anti-interference.

Classification by composition

It can be divided into basic sensor, combined sensor and application sensor.

By form of action

Can be divided into active sensor, passive sensor.
