Can you extend a thermocouple?

Extension grade wire is only used to extend a thermocouple signal from a probe back to the instrument reading the signal. The extension grade wire typically will have a lower ambient temperature limit in which the wire may be used.

Can you use regular wire to extend a thermocouple?

Do not extend the lead wires with compensating conductors that do not suit the characteristics of the Thermocouple, or with ordinary lead wires, as this would prevent proper temperature measurement. Be sure also to connect the wires using the correct polarity (+/-).

What is a Type S thermocouple?

Type S Thermocouple – Technical Information Thermocouple Type S can be used in oxidising or inert atmospheres continuously at temperatures up to 1600°C and for brief periods up to 1700°C. For high temperature work, insulators and sheaths made from high purity recrystallised alumina are used.

Can you splice a thermocouple?

YES. Temperature probes must be extended with thermocouple wire.

What is S type and R type?

Type R is identical to Type S in terms of performance, but its higher percentage of Rhodium makes it more upscale. Type S Thermocouple (Platinum Rhodium – 10% / Platinum): The Type S is used in very high temperature applications. …

Does length of thermocouple wire matter?

The length of a thermocouple has no effect on its measurement accuracy or its ability to transfer the signal to the instrument. In other words, thermocouples do not experience “voltage drops” or power loss along its length as a high current power line might possess.

What are the different types of thermocouple wire?

Type J Thermocouple Wire. Type J thermocouple wire is ideal for light industries where the temperatures range between -210°C/-346°F to 1200°C/2193°F.

  • How to extend thermocouple wire?

    How to extend the thermocouple wire? This requires the use of thermocouple compensation wires, a pair of insulated wires with the same nominal value of the thermoelectromotive force of the matched thermocouple within a certain temperature range (including normal temperature), and use them to connect the thermocouple and measure Device to

    Can you extend thermocouple wire?

    How to Extend Thermocouple Wires When thermocouple cables must be extended, Omega suggests the use of thermocouple connectors or other mechanical means. This helps to insure that the polarity is maintained (since the connectors have the polarity marked on them), thermocouple connectors are keyed to insure that they only go together in the correct manner.

    How to size thermocouple wire?

    Strip back the outer insulation

  • Strip back each individual wire and expose about .24-.5 inches of wire.
  • Bend the wire to make a contact point**
  • Weld (see next step for a suggested setup).
