Factors to Consider When Choosing a Thermocouple Gauge

Thermocouple Gauge

Purchasing a thermocouple gauge can be very difficult especially where an individual does not have the right information on what to look out for. 

It is why you should consider keenly reading through the outlined factors so that the next time you need to purchase one, you will do so without making common mistakes. 

Some of the common mistakes that individuals make are such as overspending, purchasing one that does not suit their need or getting attracted to the brand instead of considering the quality they needed. 

It is essential to note that you can never purchase a good thermocouple gauge just by considering one factor. With that said, here are a few more things to put into considerations.

  • Cost

Like any other items in the market, different thermocouple gauges will have different costs in the market. It mainly depends on the materials used in making the item. 

You may want to use those made from base metals since they are cheap but very accurate at work. You will find them being used in most industrial parks. They include types E, K, J, N, and T with K and J being the most popular. 

There are also those that are made from noble metals and include types B, R, and S. These are expensive and may go way beyond your budget in some instances. They are based on the platinum –rhodium alloy. 

Their main reason for being expensive is because platinum and rhodium are mango the most expensive metals in the world. Noble types are usable in any industrial park since they can be used at very high temperatures and still give very accurate results. 

  • Accuracy

Measuring instruments have different levels of accuracy. Your desire is to have the highest accuracy possible. Accuracy refers to the margin of error that is in the thermocouple that you are using or desire to use. 

They dictate how close you are to getting the correct figures and in some instances is referred to as tolerance. The more the accuracy of the product, the more expensive it is likely to be. 

In many instances, there is a conflict between accuracy and cost where having a higher accuracy does not necessarily mean that it needs to be expensive like you would want to think. 

It is hence prudent for you to inquire about the accuracy and compare the same with costs of a variety before settling down on a final product.

  • Temperature range

The maximum temperature that you need to measure determines the type that you need to go for. 

It is basic knowledge that you cannot purchase a thermocouple that measures less than what you need to. It would be a waste of resources and also cause you major inconveniences. 

In the end, such a product would end up useless to your industrial park and the only way out would be replacing it with one that suits your need. In most instances, the more the temperature it measures the more the money it will cost you.

  • Life expectancy

You do not want to buy an item that will serve you for only a short duration then fail. It is why durability is one of the factors that you should prioritize. Life expectancy also means the duration of time that the product will be used and give accurate results. 

The reliability of a thermocouple fails with time until at one point you can no longer make use of it. You can note this by having millivolts that are continually declining. 

However, you should know that there is an amount of decline that can be tolerated. Deterioration can be handled by recalibrating it over time. This can be done after every 3 to 6 months. 

  • Chemical resistance

This factor is very important where you need to use the thermocouple in a corrosive environment. 

Corrosion is one of the aspects that mainly contribute to wearing out and the more exposed the item is to corrosive chemicals, the faster it will fail. 

Stainless steel is highly compatible to a wide variety of chemicals which is why it is preferred by many. 

  • Installation

Different products have different installation requirements which is why you need to choose one that will give you an easy time during installation.

Easy installation also means that the item is compatible with the exiting equipment. You also need to consider how easy it is to move it from one room or industrial park to another, if the need arises. 

To make the best decision in this, you need to access the nature of your needs first. Click here to see some of the advantages you can get from using a thermocouple.

Conclusion

What you consider when buying a thermocouple dictates how well it serves your need. The very firsts step before buying one should therefore be accessing the dynamics of your needs and the money you intend to spend. That will help you know what to look for eliminating the chances of making major mistakes.
