Pressure type thermometer three most correct installation

Pressure type thermometer is according to the liquid, gas, or in a closed system of low boiling point liquid saturated steam heated volume expansion pressure changes caused by this principle, and pressure gauge to measure the change, thus the measured temperature, has been widely applied to various kinds of industrial production. Pressure type thermometer mainly consists of three parts: part bulb, capillary, instructions. This installation is in accordance with the requirements of three parts, directly determines the pressure type thermometer can play the role of itself. So, the installation of this three parts actually what should be correct? Just to look at! First is the installation of the bulb, the most important thing to notice is to insert the bulb all measured medium. If the pressure type thermometer is installed on the pipeline, so should be about half the length of the bulb placed at the center line of the pipeline, and is a top-down vertical installation. If measured medium is corrosive, don't forget to temperature synthetic cases to safeguard. Then is installed, capillary in when installation should pay attention to the capillary away from heat source or cold source, and capillary can not be folded. Finally is the instruction part of the installation, this is part of the more important, even more attention. First, indicating the height of the part to agree with the height of the bulb, if not you need to correct the zero; Second, instructions of the surrounding environment temperature to stability, in 5 - Between 60 ℃, shall not be less than or more than the scope; Third, the environment is clean, best not to have a large amount of dust and corrosive gas; Fourth, indicating part also shall not be installed in place of violent vibration, if must install, need to install shock absorbing device in the pressure type thermometer. Through the above analysis, pressure type thermometer should be installed correctly!
