Measurement instruments for pressure vessels
Thread Content
What devices are needed to measure the pressure inside a pressure vessel? Is a pressure gauge enough? What devices are needed to measure the temperature inside a pressure vessel? Is a thermometer enough? I haven’t chosen this before; I hope those with work experience can give me some advice. Thank you very much! ! ! This post was last edited by Chifeng on 2009-2-16 08:06.]
The selection must be based on the relevant parameters of the process, such as measurement range, accuracy, and installation conditions. It is possible to choose between local or remote operation as needed; attention should be paid to the installation method – flange or thread connection. In the case of threaded connections, installation components (such as mounting bosses) must also be ordered
What was said upstairs is correct; in addition to pressure transmitters and thermometers, some other accessories are also needed. For example, if you want to install a thermal resistance thermometer, you need to consider having the appropriate nozzles available in order to install it.
Take a look at the \"Installation Manual for Automatic Control Instruments\" HG/T 21581-95 – it provides detailed information.
For pressure measurement in pressure vessels, it is first necessary to select the type and brand of pressure instruments based on technical parameters such as the production process, the medium used, the operating environment, whether the measurement should be done locally or remotely, and whether it should be gauge pressure or vacuum. After that, the installation location of the instruments and the connection procedures need to be determined; these tasks must be carried out in consultation with engineers specializing in processes, piping, and installation. For any uncertainties, reference can be made to relevant technical standards such as \"SH 3005-1999 Guidelines for the Selection and Design of Automation Instruments in Petrochemical Industries\" and \"SH.T 3104-2000 Guidelines for the Installation and Design of Instruments in Petrochemical Industries\", as well as other technical regulations related to the construction of petrochemical instrument systems
It mainly depends on what your requirements are. If precision is required, a precise pressure gauge is needed; for ordinary use, a regular one will suffice.
Installing a pressure gauge requires a transmitter; what else is needed? What is needed to install a thermometer?
Pressure gauge or pressure transducer； Thermometer or temperature change
