Good quality Bimetallic Strip for sales
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 J (Iron vs Constantan) is used in vacuum, oxidizing, inert or reducing atmospheres. Iron element oxidizes rapidly at temperatures exceeding 538°C, and therefore heavier gauge wire is recommended for longer life at these temperatures.

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 0-100℃ or 0-200℃. 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 200℃, compensation grade cable is preferred. But compensation grade cable will occur enormous tested temperature value deviation if the tested temperature above 200℃. The higher the tested temperature, the greater deviation be.
  2. For compensation grade cable, the max testing temperature is less than 200℃, 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 100℃) 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)

For the extension/compensation cable, the basic structure is conductor and insulation.

To increase its temperature bearing ability and to install easily, jacket is applicable.

 

In the working environment, there are too much factors will interference the EMF signal, therefore shield layer is practical way to prevent the cable from interference caused by complex environment.
