The cryogenic temperature sensor of Meiyo which moved along with a history of LNG ship building of Japan now contributes to the world LNGC and offshore projects such as FSRU and FLNG with high technology and quality.
In 1982, first cryogenic temperature sensor was supplied to Mitsui Engineering & Shipbuilding Co., Ltd., and we have been supplying our products to more than 500 vessels so far (as of 2020). As reference, it is said that the total number of current LNG vessels is around 600 ships, we believe that you understand our high market share.
Our products are available for various types of thank shapes such as Moss, Membrane, SPB, and so on for LNGC. We are also able to produce incidental parts such as penetration fitting and sensor pockets with requested shape. In addition, even in rigging, we are able to supply terminal box with high sealing performance and intrinsically safe type barrier box. We provide total support with our production technologies and design skills which have been cultivated so far.
Followings are the equipment that our temperature sensors are available with;
● Engine/ Generator
● In-tank of Ballast, Chemical, and Fuel Oil
● Inner wall of cargo tank such as LPG/LNG
● Shaft Bearing
● Stern Tube/ Cofferdam
This sensor was developed to bury it inside of LNG tank wall. It can measure the temperature at cryogenic condition up to -200℃, and pursue the durability to withstand at the severe condition that sensor cannot exchange until peeling off the inner wall after buried once. We can produce the sensor for the cable length from 1m to more than 150m with achieving precision of Class A. After products completion, we perform a vacuum test for every sensor to check that there are not gas leaks. Single element type and double element type are available.
