Products for High-Temperature Furnaces

< Back to Catalog Products for High-Temperature Furnaces By putting Pt cap at the top, gas is slowed on its way to the thermocouple top. This prevents the thermocouple from degrading and extend its life time (over three times as long has been achieved). This thermocouple is used in glass industry and in the annealing process used for high performance ceramics and chip condensers. Components Protective Tubes Type Temperature(°C) Ceramic protective tube High Grade 1600 Ceramic protective tube Grade 1 1500 Ceramic protective tube Grade 2 1400 Quartz protective tube 1000 *The above temperature indicates operating temperature in which the thermocouple can be used for a long time in air. Insulating Tubes Type Temperature(℃) Insulating tube High Grade 1600 Insulating tube Grade 1 1500 Insulating tube Grade 2 1400 *Above temperature indicates operating temperature in which the thermocouple can be used for a long time in Air. SUS Collar Size Protective tube size A Under Φ10mm B Under Φ15mm C Under Φ21mm *Standard length of SUS collar is 100mm. *Various dimensions available. Connector Type Code Close MT-7 MT-10 Open J2 Large J2 Small Compensating Lead Wire  The compensating lead wire is used to connect the thermocouple and the temperature indicator and compensate the error caused by temperature change by connectors. There are various types of lead wires with depending on the type of thermocouple or environment of usage. We’re pleased to suggest a best lead wire appropriate to conditions.
