Cartridge Heater With Thermocouple – Read This Service Online Article About Thermocouplers.

Measurement of high temperatures, higher than 1000 C, using ceramic based thermocouples can be a well established process. To carry out this successfully the resistance wires in the thermocouple must be insulated and guarded.

The use of Ceramic materials to protect the platinum based wire is a method that has been used for many years, due to exceptional heat resistant properties of these materials. The k type temperature sensor is the most frequently used heat measurement implement and is utilized for measuring the temperature within a furnace, typically getting used to the melting or heat treatments for metal or indeed for manufacturing ceramic products.

The ceramic components within a typical thermocouple device will be the outer protection tube that is certainly subjected to the furnace. In some cases multiple tubes are utilized inside the other person to provide the degree of insulation and protection required.

Ceramic insulators (Tubes with 2 or maybe more core holes through them) are also employed to isolate the several wires that proceed to the bi-metallic joint in the head which is the point that sens0rs temperature is measured.

The standard materials for the tube is actually a 99.7% alumina material, impervious tube, that is attached typically to a metal thermacouple head, containing a terminal block which is often used to connect to a standard wire to the instrumentation. Within a less demanding heat atmosphere a mullite tube may be used like a cheaper alternative, that will work sufficiently approximately 1600 ‘oc. The mullite tube is likewise an impervious tube and has 60% alumina content.
