I search for Nichrome plate long time, and successfully bought it from Ohmalloy material. OHMALLOY provide real good service in alloy service and can always help me in finding the correct resistance alloy.

—— Mike Harness

OHMALLOY can provie me only 1kg Kovar alloy wire 1.0mm with short time, that is really amazing. Thanks

—— Janey

Really professional in thermocouple wire and cable, what i want just can get from OHMALLOY

—— Chris

Enamelled Constantan 0.08mm, i never expect to get only 2kg of it. But OHMALLOY supply it to me with good quality. God Jesus! Such a reliable supplier from china

Type T thermocouple cable TPX and TNX Fiberglass insulated


TYPE T (Copper vs Constantan) is used or in an oxidation, inert or reduced atmosphere or in vacuum. It has highly corrosion with atmospheric moisture and condensate corrosion, and high stability is exhibited at low temperatures. It is the only type with error-limited uses for low temperature temperatures.

In actual temperature measurement, usually there are long measuring distance with the measuring device, a thermocouple compensation wire is generated to compensate the temperature difference caused by the temperature change between the measuring device and the thermocouple connecting piece.


The compensation cable has the following advantages: improving thermocouple temperature measurement line physical properties and mechanical properties; improving the measurement line flexibility and making the connection convenient by using multi-strand core or small-diameter compensation wire; easy to shield external interference; reducing measuring lines cost.

Thermocouple Cable Grade

A:Extension Grade Cable

Whose wire composition is totally as the same as the thermocouple wire, remarked by the letter"X"after the thermocouple symbol number, such as"KX""JX""TX"

B:Compensation Grade Cable

Whose wire composition is different from the thermocouple wire, but its wire electromotive force (EMF) value is the same as thermocouple wire only at 0-100ºC or 0-200ºC. It remarked by the letter"C"after the thermocouple symbol number, such as"KC""JC""TC"

  1. For cost consideration, when the tested temperature under 200ºC, compensation grade cable is preferred. But compensation grade cable will occur enormous tested temperature value deviation if the tested temperature above 200ºC. The higher the tested temperature, the greater deviation be.
  2. For compensation grade cable, the max testing temperature is less than 200ºC, the bigger the cable, the smaller the signal loss.
  3. Extension cable and compensation cable comparison:


Performance Extension Grade Compensation Grade
Material Same as thermocouple Different from thermocouple
EMF Value Feature Same as the thermocouple's at certain temperature range Same as the thermocouple's
Deviation Curve Nonlinear, varies with temperature Linear
Working Temperature Range Limited(usual at 100ºC) Unlimited(depend on insulation material temperature bearing)
Line Resistance Low resistance High resistance
Compensation Contact Interference Different contactor material may cause interference None
Accuracy Low High
Price Low High(about 1-2 times higher)
