What are the main types of temperature instruments, and how can one determine if a thermocouple is damaged?
There are many types. There are thermal resistors, thermocouples, bimetallic thermometers, infrared temperature detectors, and so on. To determine whether a thermocouple is damaged, one can measure whether it still generates a millivolt signal
High-temperature thermocouples are prone to open circuits, which can be detected using a meter
Is Type B better or Type S better for high temperatures?
1. Classified by measurement method: contact type and non-contact type. Contact types include glass liquid thermometers, bimetallic thermometers, pressure-type thermometers, thermocouple thermometers, and thermal resistance thermometers. Non-contact types include optical pyrometers and radiation pyrometers. 2. As for determining whether a thermocouple is good or not, some general methods are as follows: 1) No voltage output; 2) Unstable voltage values with large fluctuations; 3) Check whether the resistance value is abnormal; 4) Verify whether it is out of specification
