THE THERMOCOUPLE 411: THE DIFFERENCES BETWEEN M-GEO VS. L-GEO STYLE THERMOCOUPLES

THE THERMOCOUPLE 411: THE DIFFERENCES BETWEEN M-GEO VS. L-GEO STYLE THERMOCOUPLES

Are you an M-Geo type of person, or would you rather go with an L-Geo? Unless you really know your thermocouples, you very well may not know. Both the M-Geo and the L-Geo share a lot of similarities, but there are a few major differences that may determine which style you should choose.

M-GEO BASICS

The M-Geo is a metal sheath or mineral insulated style thermocouple that are good for applications that require resistance to tough environments and still require consistent readings. The thermocouple has Single and Duplex element options, and sheath materials include:

 

  • Inconel 600
  • 304 stainless steel
  • 310 stainless steel
  • 316 stainless steel
  • 446 stainless steel
  • Other options available

 

 For more M-Geo specifications, check out the product details on our site.

L-GEO BASICS

While the M-Geo is insulated by magnesium oxide, the L-Geo uses loosely-packed ceramic insulators like alumina, mullite, and hafnia to protect it from harsh environments. In addition, L-Geo also has a Triplex element option and has additional sheath materials, including:

 

  • Molybdenum
  • Tantalum
  • Alumina
  • Mullite

 

 Just like the M-Geo, more product details can be found on the L-Geo page.
