Do you know what is going on in “YOUR” Industrial furnace?

Possible sources of error when measuring the temperature in your industrial furnace:

  • Incorrect selection of sensor
  • Poor location
  • Sagging
  • Induced voltage
  • Incorrect handling
  • Incorrect insertion depth
  • Contamination from the process
  • Temperature drift

Have a sales rep review if switching to an N-Type Thermocouple can improve your temperature accuracy. 


Inherent Issues with Type K Thermocouples

  • Chromel wire is subject to oxidation or green rot.
  • Sulfurous atmospheres will attack the element.

Possible Solutions:

  1. Shortening the thermocouple or tube.
  2. Selecting a larger OD protection tube.
  3. Purging the tube with clean air.

Selecting the right Protection Tube

Protection Tubes are used to protect sensors, usually thermocouples, against contaminating atmospheres and/or mechanical damage.

What Thermo-Kinetics Offers:

1) Ceramic

2) Hexoloy

3) Sialon

4) Metal 304, 316, 310, 446 Stainless Steel or Inconel 600


Selecting the right Thermowell

Leading manufacturer of thermocouples

Thermowells are used in applications where it is necessary to measure temperature at high pressure (above 75 PSIG) or in hostile environments. 

What Thermo-Kinetics Offers:

  1. Threaded
  2. Welded
  3. Flanged

Tapered vs Straight:

Tapered thermowells provide greater strength without sacrificing sensitivity. Because of its higher strength-to-weight ratio, the tapered thermowell provides greater resistance to high-frequency vibrations than straight thermowells. 


Trusting Your Temperature Measurements:

Calibration & Color Coding

Thermocouples in Industrial Furnaces 

Which one should I use?

1) “Base Metal”: Type J, K, T, E, N

2) “Noble Metal”: Type R, S, B

N Type Thermocouples

1) Offers enhanced stability at a higher temperature.

2) Superior oxidation resistance.

3) Pyrosil-D sheath provides expanded oxidization resistance and high-temperature strength. (Also available for K Types)

R & S Type Thermocouples

1) Recommended for use at higher temperatures. (0 to 1600 °C or 32 to 2280 °F)

2) Must be protected by non-metallic protection tube and insulators to avoid contamination.
