Application of explosion-proof inclination sensor in safe operation of LNG

With the growing demand for energy in China , The introduction and production of liquefied natural gas is of great importance to the optimization of China's energy structure , Effectively solve the problem of energy supply 、 Security 、 Ecological and environmental protection , Achieving sustainable economic and social development will play an important role . from 2006 Since the first LNG terminal was completed and put into operation in Shenzhen Dapeng , Successive completion （ Including under construction ）20 More than , Among them, the key equipment selected by the wharf ： Marine loading arm has been monopolized by European and American countries , high price 、 Long lead time 、 The service was not timely . Undoubtedly right LNG The safety of production and operation of the wharf brings certain constraints . The main function of marine loading arm is -163℃ Under the environment of , Transfer liquefied gas from coast to ship or ship to coast , Therefore, security and stability are particularly important .

        TB Global Technologies Ltd. (TBG) Merged by Tokyo trading Machinery Co., Ltd , Provide Petrochemical 、 liquified natural gas （LNG）、 Chemical raw materials 、 Clean energy and other equipment required for loading and unloading 、 Energy related equipment 、 And Tokyo Trade Engineering Co., Ltd., which provides sales and after-sales services as well as the development and manufacture of the above products . Its predecessor, the Tokyo Chamber of Commerce, was founded in 1947 year . The company 1955 The United States Chiksan Corp. Chiksan Exclusive agency for joints and loading arms , Start to oil 、 Electricity and natural gas industry sales .2021 year 9 month ,TBG In the Chinese market , From product 、 performance 、 Price 、 Explosion proof 、 Delivery date 、 Quality, etc , A series of domestic manufacturers were evaluated and selected , And finally choose to cooperate with Zhichuan , Provided by Zhichuan to meet explosion-proof requirements and CCC Certification requirements High precision inclination sensor , Applied to its marine loading arm .

        ZCTxxxxN-LBQ-Ax-H5-4600B It was developed by Zhichuan Technology High precision digital explosion-proof inclination sensor , 5V Power supply ,RS485 Interface , compatible Modbus RTU agreement ; The products used in this series include two main models , among ：

• • ZCT230N-LBQ-AH-H5-4600B It is a two axis version , Horizontal installation , range ±30°, precision ±0.005°
  • ZCT1360N-LBQ-AV-H5-4600B It is a single axis version , Vertical installation , range 0~360°, precision ±0.01°

        This series of products adopt aluminum alloy shell , Protection level IP67, At the same time, it has obtained explosion-proof certification （Ex ia IIB T4 Ga） And the country CCC authentication , And installed for TB Global Technologies Ltd. (TBG) Of LNG Angle detection of marine loading arm .

        With the development of the times , Zhichuan technology products have obtained more and more certifications , More and more categories , Its application field is also more and more extensive . except LNG Marine loading arm angle detection application , Other types of explosion-proof inclination angle of Zhichuan technology are also applied to hydraulic supports in coal mines 、 Tank car tank tilt compensation, etc .
