PTFE/FEP INSULATED THERMO COUPLE & RTD WIRES

A thermocouple is a junction of two dissimilar metals which generate a voltage proportional to the temperature of the junction (called seebeck effect). For many industrial heating processes, particularly those carried out at high temperatures, a thermocouple is the most accurate, convenient and simple method of temperature measurement. In some instances, it is the only feasible method.

Product Features:

• High temperature continuous use â€?00 to 260°C upto 400°C for few seconds
• Excellent chemical, electrical and mechanical properties
• High reliability, small size and highly fire resistant
• 100% tested

Thermocouple wires and extension cables:

The standard PTFE/FEP Insulated thermocouple combinations offered with 7, 19 strands of 0.2 mm or 0.25 mm dia strands. ±0.75% temperature tolerance as per IEC 584-2 class specs are:

Construction:

Cores as pairs (on separate spools) or Planetary strain free Twisted, or parallel laid;

Kapton isolator , with or without SPC or NPC braid, PTFE/FEP jacket of prescribed standard colours, with or without S.S. over braid. Standard jacket colours- for type T-Brown, type J- Black and type K –Green.

We offer different core and jacket colour, 14 / 0.2 mm conductors, parallel lay design, special tolerances and other types of thermocouples wires and customized construction for thermocouple cables. Contact us for additional information.

We make Class 1, class 2 and extension thermocouple cables.

RTD WIRES

• Greater stability, accuracy, repeatability in some cases than thermocouple cables
• Low drift, suitability for precision, wide operating range

Construction:

AWG 24/7/32 (0.2mm), SPC or NPC, Type E, PTFE/FEP insulated 0.2 mm RTI, two cores Red �White, 3 cores Red- Red �White, 4 cores Red- Red �White �White sequence, strain free planetary twisted, kapton isolator, SPC / NPC braid shield, specified colour PTFE jacket 0.25 mm RTI or more. Many combinations possible.

Note:

• SPC is used for 200°C;  NPC upto 260°C
• TPC with FEP can be used upto 150° C
• The product referenced above represent the most popular constructions. Other constructions can be manufactured to meet individual specification and application requirements. Contact us for additional information.
• RTI means Radial Thickness of Insulation.

How to select

• Thermocouple Type Selection
• Construction Selection

Garg Advantages

• 100% finished product testing with actual test certificate.

Advantages of PTFE as insulation Material

• PTFE is one of the lowest dielectric constant and loss factor material
• Inert to practically all chemicals even at elevated temperatures
• Fire (flame) proof and non inflammable
• Smaller size, lighter weight and much higher reliability
• Excellent thermal stability for use from -200C to 260C

Thermo couple extension and compensating cables

Extension/Compensating cables are used for remote temperature measurements with thermocouples. They serve as an extension from the thermocouple to the measuring device. Thermocouple Extension cables must be of the same material as the thermocouples and compensating cables of material having the same thermo-electric characteristic as the thermocouple within the given temperature range. These can be offered with PTFE/FEP insulation.

We offer different core and jacket colour, 14 / 0.2 mm conductors, parallel lay design, special tolerances and other types of thermocouples wires and customized construction for thermocouple cables. Contact us for additional information.
