All You Need To Know About Microbead Thermocouples

Microbead thermocouple is a specially designed temperature sensor by Therm-x for complex temperature measurement devices. The medical industry has many application areas for this temperature sensor. This is because such devices are attached or inserted into a human body for certain diagnosis and procedures. These devices can be extremely complex and small. Another important factor is they should be clean and absolutely free of any contamination, and Therm-x complies to this aspect at any cost. The company has its set standards for cleanliness, superior quality of systems, and capacity. This post discusses the details, beneficial features, and application areas of Microbead Thermocouple.

Microbead Thermocouple Described at Length

Microbead thermocouple is typically meant for rapid response temperature measurements. When compared with a fine wire thermocouple in terms of temperature measurement speed and other factors. Some experiments conducted show a stark difference in the stats in terms of temperature fluctuations and vertical velocity fluctuations. With the entire focus on the medical industry, these thermocouples are made of medical-grade and approved materials such as 40-44 AWG standard bifilar polyimide insulated thermocouple wire and medical-grade bonding materials. One end of the thermocouple is the termination end, which is about half inches and not insulated. The other end is welded and soldered for fusion, and is also not insulated. The exposed hot junction due to welding is isolated by using a non-conductor such as Teflon, polyimide, polyester, or nitinol tubing. These are medical-grade overtube materials. The overtube covers the welded joint. The middle portion is covered by a non-conductor insulator such as polyimide. This thermocouple is about 28ʺ long.
