Main advantages
1, high measuring accuracy. Because of direct contact with the object being measured, not under the influence of medium.
2, wide measurement range. Commonly used heat from the continuous measurement of lingxia50du-1600, some special thermocouple minimum measurable-269 degrees (such as Fe-NI-CR), up to a maximum of 2800 degrees (such as tungsten, rhenium).
3, the structure is simple, easy to use. Thermocouples are usually made up of two different kinds of wire, and are not subject to size restrictions and opening, outer protective casing, it is very convenient to use.
Selection method
Choice when selecting a thermocouple thermocouple needs to consider the following factors:
1, the measured temperature range;
2, the required response time;
3, the connection point type;
4, thermocouple or sheath material resistance to chemical corrosion;
5, abrasion or vibration;
6, installation and constraints, and so on.
