How to correctly choose thermocouple heat tube material

In some cases, do not use the heat pipe may cause irreversible damage to the temperature sensor. In this article, we'll explain what is hot casing, why need a thermocouple heat tube, and when choosing a hole for your project should follow the process of

thermocouple thermal casing is used to protect industrial temperature sensors in the process of tubular components. They are included in and installed in process flow in the tube closed at one end. The thermometer, thermocouple and RTD temperature sensor open end inserted into the pipe. Process fluid heat transfer heat to the casing wall, thermal casing wall and heat transfer to the sensor.

high speed or high pressure can bend a thermometer or warp and continuous exposure to certain materials, may lead to equipment corrosion and corrosion. Hot casing is designed to protect your temperature device from these expensive accident.

hot casing also make sure the temperature device does not come into contact with the measured materials, protect the material from pollution. It is crucial for many applications such as wine maker, it needs to be monitored throughout the fermentation temperature and no pollution products.

it also brought extra benefits, allowing you to repair or replace the thermometer, not drained container or no material leakage.

useful thermocouple thermal casing is that they have a disadvantage. Due to increase the quality of the sensor response to process the temperature change is delayed. This makes the thermal casing is not suitable for need to measure the application of rapid temperature change.

your material: this is the first step to select your thermocouple heat tube. Choose materials is the most important factors to determine the well will expose corrosion conditions. About our most commonly used material and the corrosion resistance of detailed information, please read our blog & other; Sheath material hard practical & throughout;

connection: there are different ways to connect your hot casing.

threaded connections to provide mechanical strength, and if necessary, to allow easy to remove.

will be well welded in place to provide the best seal.

flange thermocouple thermal casing by the welding of flange to the top quality bar. Then connect the flange bolts to provide strength the location of the well.

insert length: the length of the inserted into the pipe in the well for & other; U” Size. It said into the processing container or insert depth of pipeline system, and from the thread below to the tip of the heat pipe measurement. U length should be equal to or more than temperature sensitive part of the instrument.

aperture, aperture should adapt to the temperature sensor used sheath diameter.

conical or straight shank: straight shank hot casing along the well in length with the same size, usually used in the standard load application. , taper shank provide greater stiffness sensitivity did not change, should be used to involve high vibration, pressure, temperature and speed of heavy duty applications.

select thermocouple thermal casing is a difficult process, involving many factors. Contact our sales team, they will be glad to assist you to find the perfect thermal casing for your project.
