K-type thermocouple probes

Wide variety of thermocouple probes for many applications

SKF offers a range of K-type thermocouple probes for use with SKF Thermometers.
Typical applications are:
  • Surface measurements (TMDT 2-30, -31, -32, -33)
  • Gas and liquid measurements (TMDT 2-34)
  • Semi solid materials (TMDT 2-35)
  • Clamp for pipe measurements (TMDT 2-36)
  • Rotating surface measurements (TMDT 2-40)
  • Liquid non-ferrous metal measurements (TMDT 2-41)
  • Ambient temperature measurements (TMDT 2-42)
  • Gas measurements - wire probes (TMDT 2-38, -39)
  • Heavy duty surface measurements (TMDT 2-43)
All probes can be used with the SKF Thermometers without recalibration.

Designation
Description
TMDT 2-30
Standard surface probe.
For hard surfaces such as bearings, bearing housings, engine blocks, oven shields, etc.
Max. temp. 900 °C / 1 650 °F .
Response time 2,3 sec
TMDT 2-31
Magnetic surface probe.
For hard, magnetic surfaces; the integral heat sink design and the low mass minimise thermal inertia and provide an accurate temperature measurement.
Max. temp. 240 °C / 460 °F
Response time 7,0 sec.
TMDT 2-32
Insulated surface probe.
For hard surfaces where electrical wiring might cause short circuiting, e.g. electric motors, transformers, etc.
Max. temp. 200 °C / 390 °F
Response time 5,5 sec.
TMDT 2-33
Right angle surface probe.
For hard surfaces in heavy duty applications, e.g. machine components, engines, etc.
Max. temp. 450 °C / 840 °F
Response time 8,0 sec.
TMDT 2-34
Gas and liquid probe.
Flexible shank made of stainless steel, for liquids, oils, acids, etc. and at high temperature, e.g. open fire (not for molten aluminium).
Max. temp. 1 100 °C / 2 010 °F
Response time 12,0 sec.
TMDT 2-34/1.5  
Gas and liquid probe.
Same as TMDT 2-34, but with thin shank and faster response time. Very flexible, specially suitable for measuring temperature of gases.
