When positioning probes, it is crucial to consider the desired test conditions, particularly temperature and flow rate

​Over the years, the technology behind electrical resistance probes has undergone significant advancements, transforming it from its early manual and portable form to an advanced automatic recording system capable of online monitoring. This evolution has made resistance probe monitoring a standard practice in China's refining sector post-2000. The technology is highly regarded for its exceptional sensitivity, rapid response, robust anti-interference capabilities, and broad applicability.
