The shockproof pressure sensor is the most commonly used sensor in industrial practice. It has shockproof function and has a certain benign response in case of various shaking. It is widely used in various industrial automatic control environments, including water conservancy and hydropower, railway transportation, intelligent construction, production automatic control, aerospace, military industry, petrochemical, oil well, electric power, ship, machine tool Pipeline and many other industries.
The integrated sensor is manufactured with standard process technology for producing silicon-based semiconductor integrated circuits. Usually, some circuits used for preliminary processing of the measured signal are also integrated on the same chip.

The main business is Keheng (300340.SZ), which is a rare earth luminescent material, lithium battery and LED display project. In 2014, it achieved operating income of 390 million yuan, a year-on-year increase of 2.64%; net profit has a certain loss.
Keheng shares said that the main reason for the loss is that the operating income of rare earth luminescent materials is affected by the decline in the prices of rare earth raw materials, the downward adjustment of the company's product prices, and the replacement of energy-saving lamps by LEDs. The growth of other business activities, including lithium materials, may not be able to hedge the decline in the business of rare earth luminescent materials.
This has also prompted Keheng to accelerate the transition to LED materials and lithium materials.
"Last year, we have been vigorously developing phosphor projects in the LED field." Chen Tao, general manager of the LED and Photobiology Division of Keheng, told reporters that some domestic packaging plants and lighting factories have established cooperative relations with Keheng.
As LEDs enter indoor lighting, the requirements for light efficiency and display are getting higher and higher. Keheng shares develops phosphors for LEDs with its research and development strength and technical process precipitated by energy-saving lamps. The preparation of the nitride red phosphor is mainly used to adjust the color temperature and improve the color rendering performance of the white LED. According to reports, this project product has been certified by customers and used in mass production.
From 2011 to 2014, Keheng's operating income was 1.008 billion yuan, 427 million yuan, 380 million yuan and 390 million yuan respectively. The investment in research and development has been maintained at around 3% of revenue, and this year in the LED business. The investment in the ministry will be higher.
Wan Guojiang, chairman of the company, said that the decline in performance will not affect the confidence of the company's management and employees. "Technology excellence, eternal pursuit is our long-standing philosophy. The company also believes that through the expansion of business, it will soon pass this seemingly low period."
In August 2013, Keheng Co., Ltd. completed the acquisition of Shenzhen Lian Teng Technology Co., Ltd., which enabled the company to successfully enter the LED terminal industry. The main business of Lian Teng Technology includes the development, production, leasing and sales of LED electronic display and LED lighting. While making considerable contributions to the performance of Keheng, it is also the beginning of Keheng's acquisition of M&A as an important means for the company's future development.
"The company's development is mainly based on the existing technology, technology and other foundations to expand, that is, related diversification. Self-development is beneficial through independent research and development or cooperative research and development model, if there are projects or enterprises suitable, it will also try out the extension model such as mergers and acquisitions. "Tang Xiulei, the director of Keheng shares, said in the reception of institutional investors that the decline rate of the rare earth luminescent materials industry will slow down in the future, and in the long run, it will focus on the development of LED and other special varieties of luminescent materials. 
Keheng's 2014 LED project revenue exceeded 40 million yuan
[Text|High-tech LED reporter Yue Mengdi] Under the situation that the price of rare earth luminescent materials has been falling all the way and the market is sluggish, Keheng has begun to accelerate its transformation into LED engineering and lithium materials. In 2014, Keheng's LED project revenue reached 45.544 million yuan.
