Thermocouple alloys and cables

Quantity:
Feature
 
  Thermocouple alloy(TYPE K, E, J, T) has a high thermal electromotive force. There is a linear relationship between temperature and thermal electromotive force. The thermal electromotive force has long-term stability. It possesses many advantages, including accurate and sensitive temperature, large measurement range, reliable performance and good mechanical strength. Thermocouple alloy(TYPE K, E, J, T) manufactured by our company have been widely applied in producing temperature measurement component in departments of national defense,scientific research, metallurgy and chemical industry. 
 
BoSheng’s product program for thermocouples includes:
 
Thermocouple wire - round and flat
Thermocouple strip
Bunched wire

Shielded:
All above thermocouple and extension wire can be finished with a shield (Stainless steel-SSB / Aluminum -AL/ Copper-Cu), If you need the wire with a shield, please add “SSB” or “AL” or “CU” to the Order No., such as “K-PFA-SSB-PFA-20”, it means Type K, 20AWG, Solid, Conductor insulation: PFA, Metal shielded: Stainless steel, Overall insulation: PFA. 

 

Overbraids:
All above thermocouple and extension wire also can be finished with a metal overbraid to give added protection from abrasion and mechanical damage.
Stranded Overbraids:
- Stainless Steel(SSB)
- Tinned Copper (TCB)
