Sapphire heat pipe thermocouple is the ideal choice of the gasification reactor applications

Thermocouple protection tube with airtight sapphire.

on April 1, 2009 - Suitable for gasification reactor applications, rosemount & reg; Thermocouple temperature for 3200 & deg; F, under the difficult conditions of the pressure of 110 bar provide longer service life. Protection of sapphire tube is corrosion resistant, gas penetration, and with the support sleeve hermetically sealed. In the case of probe disconnect, redundant sealing system to prevent toxic emissions released from the reactor. All seals with nitrogen pressure test is carried out under the 110 bar.

Emerson has introduced sapphire heat sleeve rosemount thermocouple, is the ideal choice of the gasification reactor application

the new sensor with a gas-tight hot casing harsh temperature and corrosion conditions can prolong the service life of the three times CHANHASSEN, MINN. （ On March 31, 2009) - - Emerson Process Management introduced a belt tightness sapphire rosemount thermocouple protection tube, used for gasification reactor applications. New type thermocouple is specialized development, but also extend the service life of work under the harsh process conditions, including temperature as high as 3200 & deg; F, pressure up to 110 bar, as well as from the erosion of gas led to standard thermocouple premature failure. Rosemount insulated thermocouple wrapped in special protection tube made of sapphire business growth, the sapphire as naturally occurring varieties, with good corrosion resistance and gas permeability. The improved design makes can significantly extend the life of the sensor (6000 to 18000 hours Depending on the application) Accurate and reliable measurement. This is usually a standard thermocouple life three times. By reducing the number of unplanned shut down due to sensor fault, increase the production output. Life costs are lower, because a longer working life has reduced the number of the replacement sensor. Rosemount design is a characteristic of sapphire, protecting tube and supporting bushing gas-tight seal. This improves security and for this type of thermocouple provides the longest life expectancy in the gasification reactor. In the case of probe fracture, exist to prevent toxic emissions released from the reactor redundant sealing system. All seals before delivery with nitrogen gas to conduct stress tests of 110 bar. Connected by forging steel shell, it avoid hydrogen gas leak from the reactor. New high temperature thermocouple components can use with rosemount 3144 p type temperature transmitter, used for key control and security applications. Transmitter contained in the prediction of thermocouple deterioration diagnosis can provide alarm through changes in the resistance of the thermocouple to further improve the plant availability. This enables maintenance personnel before the unplanned shut down plan the replacement of thermocouple, thereby minimizing costs and plant downtime. New rosemount have sapphire protection tube of thermocouples is suitable for the oil and gas, agriculture, oil refining and chemical industry are widely used. It joined Emerson existing rosemount temperature sensors and accessories series, suitable for high precision, durability and long-term stability of the industrial environment.
