Seeking expert help with a thermometer issue
Thread Content
In the neutralization tank, our company’s thermometer extends two-thirds of its length into the tank along the tank wall; there is stirring inside the tank, and the bottom end of the thermometer can easily get covered by calcium oxide, resulting in a discrepancy between the actual temperature and the temperature indicated by the thermometer. Do any experts have any good solutions? Additionally, there is an unrefined idea: whether it would be possible to do without thermometers and use temperature sensors or something similar in their place. I would appreciate guidance from those who are more experienced.
A thermometer consists of two parts: a temperature sensor and a temperature display. There are two methods of measurement: direct measurement and indirect measurement. Direct measurement is more accurate; as the original poster mentioned, it’s best to establish a schedule for regularly cleaning the temperature sensor ； Indirect measurement involves sensors that do not come into contact with the medium being measured; for example, infrared thermometers, and their accuracy is relatively lower. You can choose the appropriate thermometer based on your requirements for measurement.
