According to the analysis of the overall thermal resistance during installation, must satisfy three conditions, is a help to ensure the accuracy of temperature measurement, the second is the use of safe and convenient, the third is the easy maintenance. In addition, still need to meet in the process of production operation, will not affect the production and operation of the equipment. So, in choosing the thermal resistance of the installation site and insertion depth when actually what problem should note?
aiming at this problem, it must have a lot of friends are concerned. Let's to analyze for everyone. First of all, in order to make the measurement of thermal resistance end and get sufficient heat exchange between measured medium, you need to reasonable selection of observation. Remember, try not to choose the valve, elbow and pipe and equipment near the corner of the site.
the second note is a key problem as much as possible in order to improve the measurement accuracy, but also to reduce heat loss, so need to make enough thermal resistor insertion depth. Such as the fluid temperature in the center of the measuring tube, usually is the measuring end is inserted into the pipe center, can choose vertical installation at this time, also can be tilted to install. If the current body pipe diameter is 200 mm, then the insertion depth should be 100 mm.
need to remind everybody is, if the measurement is some high temperature and high pressure and high speed of fluid temperature, and then by as much as possible reduce the cases of fluid resistance, but also to prevent the case break under the action of a fluid, and therefore need to adopt protection tube shallow way, or is the use of hot shell heat resistance.
in addition to the above described the content, if the insertion depth of the measuring element in more than one meter, is to choose the vertical installation way, or for heat resistance with racks and protect casing.
