Thermocouples Types S,R,B
Thermocouples Noble Metal
 Industronic's noble metal thermocouples offer
the advantage of handling higher temperatures and providing
greater accuracy than base metal thermocouples. Choose form ANSI
types S, R, or B, depending on your temperature and tolerance
requirements.
Noble metal thermocouples can be ordered as bare elements,
elements with insulators, or assembles. A typical assembly
includes a head, alumina insulators, and a protecting tube. A
variety of hardware choices are available
Performance Capabilities
- Platinum assemblies can handle temperatures to 3100ºF Applications
- Heat treating and control sensors
- Semiconductor C.V.D. processing
