During the maintenance of the furnace temperature tester, it is found that the high temperature damage of the furnace temperature tester is very serious. What is the cause
According to the consultation, there are three reasons: first, the tester of the furnace temperature tester is a novice, without the guidance of an experienced engineer, and thinks that the heat insulation box is only the box for the instrument, which is directly put into reflow soldering or wave soldering when measuring the furnace temperature; second, the heat insulation box of the furnace temperature tester is not well maintained, damaged or continuously used in high temperature, which leads to the damage of the heat insulation effect of the heat insulation box, namely The heat insulation effect of the thermometer in the heat insulation box is not good; third, the user does not know or unconsciously understand the performance of the heat insulation box of the furnace temperature tester, thinking that as long as there is a heat insulation box, no matter how high the furnace temperature is and how long the measurement time is, the furnace temperature tester can be put into the furnace to measure the furnace temperature. In fact, in the final analysis, the user does not know how to select and use the furnace temperature tester insulation box correctly. As a manufacturer of furnace temperature tester in Shenzhen, an online monitoring system for furnace temperature and a customized insulation box for furnace temperature tester, it has various types of temperature detectors such as wave soldering thermometer, reflow soldering thermometer, selective wave soldering furnace temperature tester, as well as customized insulation boxes for furnace temperature testers with different sizes and different temperature resistance conditions. It has rich data. Let's discuss it with you.
The main function of the insulation box of the furnace temperature tester is to insulate and protect the furnace temperature tester from high temperature damage, so as to ensure that the furnace temperature tester works at a suitable temperature. For example, the three mainstream brands in the market, bestemp furnace temperature tester, KIC furnace temperature tester and datapaq furnace temperature tester, all use K-type thermocouple to measure temperature, and the measuring range is - 40 ℃ - 1380 ℃. However, the temperature measuring range is not the ambient temperature of the furnace temperature tester, which depends on the heat insulation effect of the heat insulation box and the temperature resistance of the temperature measuring line. If the heat insulation effect of the heat insulation box does not match the ambient temperature, the furnace temperature tester will automatically shut down, or even the main board of the furnace temperature tester will burn out.
Therefore, when customers ask us about the furnace temperature tester, we will ask about the furnace type, furnace height, furnace temperature curve, measurement time, measurement frequency, etc.
