Thermocouple Wires and Cables

Thermocouple wires and cables

In most thermocouples, the wire and cable of the thermocouple are used when they are connected to the display. Thermocouple wires and cables are made in two types of thermocouple compensating cables or thermocouple sequence wires. These cables themselves can be in two types of filament or wire models.

Thermocouple cables are used in most different industries and their main purpose is to reduce the final labor costs. These cables transmit the obtained temperature with high accuracy. Also, to select the appropriate thermocouple sequence wire, you should consider different conditions such as ambient temperature, humidity, noise, path length, etc.

Thermocouple Wires and Cables

What is a thermocouple wire and cable?

The thermocouple cable is made of alloy and the material used in the thermocouple. In other words, the same type of alloy that is used in thermocouple wires is also used in thermocouple sequence wires. There are two different types of thermocouple wires and cables, which are divided into the following two groups:

Introducing different types of thermocouple wires and cables Thermocouple sequence wire

The thermocouple sequence wire has high accuracy and suitable in data transmission work. The material of this cable is similar to the material used in thermocouples and has the same degree of accuracy. These types of wires are usually determined by adding the letter X to the continuation of the thermocouple model. Consider KX, JX, etc. wires, for example. This symbol on these wires means that the cable in question is used for the K-type thermocouple. Thermocouple compensator cable
Compensating cables are another type in which the materials and alloys used are used for a certain temperature range. In principle, these types of cables are used for a certain range of temperature and have a good and high accuracy and, like the tail wire, generally do not support the temperature range of the thermocouple. These types of cables are identified by adding the letter C at the end of the thermocouple type. For example: KC, JC and so on

When choosing a thermocouple cable, you should pay attention to the following:

1. Chemical and mechanical durability and stability against various environmental conditions and climatic conditions
2. Temperature range that supports
3. Strength and stability of coatings and their insulation
4. The degree of flexibility
5. External temperature
6. Monitoring and so on

In addition to the above, there are many cables with two or more conductors. Also, many thermocouple wires can be custom designed and manufactured and made and delivered to the customer according to his needs and desires. Advantages and applications of thermocouple wires and cables
• Resistance to temperatures above 400 degrees and in some special conditions the resistance of wire with silk insulation increases up to 1200 degrees.
• High mechanical strength due to metal insulation
• High flexibility makes this cable easy to install and portable.
• High application in hot furnace walls
• Use it easily in the cable tray.

Important Note: Note that this cable should not be used in damp and wet places where it rains a lot due to water or steam entering it and the possibility of connecting.

What makes a thermocouple cable so important?
The reason why this cable is important is that when measuring the desired ambient temperature by sensors, the voltage transfer that occurs must be properly and accurately and without changing it to the next stage, which is the control stage. to be given.How can you buy a thermocouple wire and cable?
Due to the many applications and uses of this cable, you can purchase thermocouple wires and cables either in person from Tehran Sadra store or order this product online from the website

What are the common problems in buying thermocouple wires and cables?

If at the time of purchasing this cable you do not have good information about the features and applications of this cable and you do not know the use of any of them, the risk of your wrong choice in the purchase increases and will waste your money and may be irrelevant products. And buy poor quality for your work and cause a setback in the work process and a waste of your capital. For this reason, before buying, have a clear and complete mentality about buying or get help from an expert and skilled in this field.
PVC coating:

This coating is widely used in humid environments due to its low price and high resistance, and can be used in the temperature range of minus 20 degrees to positive 80 degrees Celsius. Refractory glass fiber coating:

This coating is one of the main and most common coatings of thermocouple wires and is very popular in the industry due to its high resistance to heat, corrosion in various chemical environments. The disadvantage of this coating is that it is not resistant to moisture and damp and you should never use this type of coating in humid environments. The temperature range of this coating is between 20 to 270 degrees Celsius. Silicone coating:

Silicone coating is one of the most widely used coatings in thermocouple wires and has a high resistance to oil, heat and humid environments. The use of this coating in acidic environments is not recommended at all. The temperature range of this coating is from minus 60 degrees to positive 250 degrees Celsius. Teflon coating PTFE, FEP:

This coating is one of the best coatings among thermocouple wires and cables and has high resistance to heat, chemicals, moisture, electricity, physical destructive factors such as scratches, twisting and so on. The temperature range of this coating is from minus 100 degrees to positive 260 degrees.
