FerroSafe® series thermocouples for Molten Metal application
[00:00:05] Introducing the FerroSafe® series thermocouples, engineered for high-temperature accuracy and built for extreme molten metal environments.
[00:00:17] Designed specifically for the non-ferrous metal industries, this industrial sensor delivers precise temperature measurement where failure is not an option. It comes with various options, including a rugged handle, lead wire, and digital reader.
[00:00:28] At its core is a rugged metal sheath protected by our proprietary ceramic coating. This unique non-wetting layer ensures longer sensor life and reliable performance in direct molten metal contact.
[00:00:37] With a reduced tip for fast-response sensing and a thermal conductive coating for consistent readings, the FerroSafe responds in under 8 seconds—perfect for real-time process control.
[00:00:45] Available in Type K and Type N calibrations and built to ASM, IEC, and ANSI standards, these sensors meet Class 1 and Class 2 accuracy for high-confidence data when it matters most.
[00:01:06] Choose from coated or uncoated versions depending on your application needs, withstanding temperatures up to 900°C or 1600°F.

Find answers to common questions about the TC102 Thermocouple
For oxidizing atmospheres, consider 310 or 446 stainless steel, or Inconel 601 for more severe high-temperature service. For reducing atmospheres, Inconel 600 is generally preferred. 304 or 316 stainless steel may suit lower-temperature, less-corrosive applications. Always confirm compatibility with the furnace temperature and gas composition.
Choose a beaded thermocouple element when a simple, economical construction and relatively fast response are priorities. The TC102 datasheet notes that beaded elements have low mass and therefore provide a fast response, but they are not recommended for highly oxidizing environments.Choose an MGO-PAC element when you need a more rugged construction with the thermocouple wires supported inside a mineral-insulated sheath. The TC102 is available with grounded or ungrounded MGO-PAC junctions, giving flexibility for different furnace and instrumentation requirements
A larger diameter or heavier-wall protection tube generally provides greater mechanical durability, but the additional mass can result in a slower temperature response. A lighter construction generally responds faster but provides less mechanical protection. For the TC102, Schedule 40, 80 and 160 protection-tube options are available. Selection should be based on the required mechanical protection, process conditions, and acceptable response time
A duplex thermocouple is useful when redundancy or two independent temperature signals are required from the same measurement point. The two elements can support separate control and monitoring systems or provide a backup signal if one measurement circuit fails. For applications requiring only one temperature signal, a single-element thermocouple is typically sufficient. The TC102 is available with single or duplex elements
Yes, The TC102 can be configured for replacement applications with different process connections, flange sizes, connection heads and extension lengths. When replacing an existing furnace thermocouple, provide the existing sensor’s thermocouple type, protection tube size and material, insertion length, flange or thread connection, and connection head details so the TC102 can be configured to match the installation as closely as possible
Premature failure can occur when the protection tube material or thermocouple construction is not properly matched to the furnace temperature and process conditions. Excessive temperature, thermal cycling, oxidation, corrosive atmospheres, vibration, and mechanical stress can shorten sensor life. Selecting the correct protection tube material and construction for the actual furnace environment is important for reliable operation. The TC102 offers multiple stainless steel and Inconel protection tube options to accommodate different process requirements
