| PTFE Electronics is leading manufacturer of SILICONE TUBES in Himachal. A thermocouple cable is a cable made of two dissimilar metals that enables accurate measurement of temperature and is widely used in industrial heating processes, particularly those carried out at high temperatures. It consists of two dissimilar metals, joined to form a junction, which when heated produce a thermoelectric voltage (EMF). This voltage changes as the temperature increases or decreases. The resultant EMF (Electro Motive Force) is proportional to the temperature difference between the junction and is measured and interpreted in millivolt by using the thermocouple thermometer. For connecting the thermocouples to the temperature indicators Extension and Compensating cables are used. |

What are the different thermocouple types?
Thermocouples are available in different combinations of metals or calibrations which are suitable for different measuring application. Most common calibrations are J, K and T. Each calibration has a different temperature range and environment, although the maximum temperature varies with the diameter of the wire used in the thermocouple,thicker elements withstand higher temperature and have longer life. The diameter of the thermocouple has a significant effect on response time also. A smaller diameter results in a quicker response, but is less durable than a larger diameter thermocouple.
We manufacture only J, K and T type thermocouple wires under PTFE and Fiberglass Insulation.
-
J Type (Iron-Constantan) – Temp Range -ve 40°C to +ve 750°C
-
K Type (Chromel-Aluminium)– Temp Range -ve 200°C to +ve 1350°C
-
T Type (Copper-Constantan) – Temp Range -ve 200°C to +ve 350°C
Extension Cables are manufactured from conductors having the same nominal composition as well as the same emf output as those of the corresponding thermocouple. Letter ‘X’ following the designation of the thermocouple, e.g. KX, denotes these cables.They serve as an extension from the thermocouple to the measuring device. We manufactures JX, KX and TX type extension cables.
Compensating Cables are manufactured from conductors having different composition from the corresponding thermocouple but have similar emf output over a limited temperature range (generally 200°C). Letter ‘C’ following the designation of the thermocouple, e.g. ‘KC’, denotes these cables.
We manufacture RTD, Thermocouple Extension and Compensating cables with the PTFE and Fiberglass Insulation. We make following constructions commonly with parallel as well as twisted form.
