STANDARD SPECIFICATIONS FOR THERMOCOUPLES

• Unless otherwise specified, all Thermocouples conform to the following specifications:
  
  

• All Thermocouples according to ASTM 230 Type T, J, E, K, N, R, S, B, W5.
  
  

• Special Limits of Accuracy.
  
  

• Temperature Range: ________
  
  

• Grounded or Ungrounded Junctions are available.
  
  

• Wire configuration: _____AWG
  
  

• Leadwire Insulation.
  
  

• Lead Length = _________ 
  

• Lead wire ends stripped and tinned approximately ½" long.
  
  

• Stainless Steel Sheath= __________
  
  

• Sheath Length = _______
  
  

• Sheath is Mineral Insulated Cable filled with MgO.
  
  

• Leads will be epoxy sealed to inhibit the intrusion of moisture.
  
  

• Each probe will be etched with lot number to provide traceability.
  
  

• Response time: Dependent upon type of junction. Contact Engineering for details.

Type N Thermocouple (Nicrosil / Nisil): The Type N shares the same accuracy and temperature limits as the Type K. The type N is slightly more expensive. The type N has better repeatability between 572F to 932F (300C to 500C) compared to the type K.

Type N Temperature Range:

• Maximum continuous operating temperature: up to 2,300F (1,260C)

• Short term use: 2,336F (1,280C)

• Thermocouple grade wire, -454 to 2300F (-270 to 1,260C)

• Extension wire, 32 to 392F (0 to 200C)




• Type N Accuracy (whichever is greater):




• Standard: +/- 2.2C or +/- .75%

• Special Limits of Error: +/- 1.1C or 0.4%




• Consideration for bare wire type E thermocouple applications:

• The type N holds up better to oxidation at high temperatures when compared to the type K.
