Having electromechanical devices that support the inflow of signal between rotating and stationary structures makes production more accessible. With slip rings, manufacturers can continuously relay information and data without worries of leakage, mix up, or breakage.

It can be challenging for any manufacturer who is working under high temperatures. That is because, under normal circumstances, standard slip rings can only withstand the heat of below 80°C. Thus, using an average slip ring is impractical and expensive.

What Happens When Manufacturers Use Extreme Temperatures?

Thanks to the technology, slip ring manufacturers have come up with a slip ring for high temperatures. It can withstand high temperatures and still performs all tasks with efficiency. Read here how the slip rings work and their applications.

What Is a High-Temperature Slip Ring?

A high-temperature slip ring is an electromechanical device that transfers signals and currents between rotating and stationary structures under extreme temperatures. Extreme means temperatures above 80°c and can be up to above 250°C.

Many manufacturing processes involve high temperatures. Where there are many rotating devices, the use of slip rig seems practical, right? Having a slip ring that withstands high temperatures is a relief to manufacturers who want efficiency, low maintenance cost, and high production.

The high-temperature slip ring consists of high-quality materials that resist heat. Moreover, they are durable and efficient to work under extreme conditions. Every manufacturer who specializes in making the slip ring makes sure that it undergoes all the testing. Thus, the end product serves the purpose.

High-Temperature Slip Ring Features

What are the features that make the slip ring exceptional and stand out from the others? The slip rings are unique due to how manufacturers make them. The following are the features that make the slip rings suitable for high temperatures:

1. Heat resistant

It is the standing feature that makes it the best in high temperatures. These slip ring can withstand high temperatures and remain efficient. That is because manufacturers make the slip rings with a coating of gold, which is resistant to heat.

2. It has a compact structure

Unlike other slip rings, the high-temperature slip rings have a small structure in design that enables it to perform to its best. Also, during the process, it produces less noise and toque. Manufacturers use various methods to make sure the slip ring is resistant to heat around it.

3. Can rotate a continuous 360°rotation

The purpose of a slip ring is to transfer signals and current in rotating structures. For the high-temperature slip ring, it means power, signal, and data transmission by continuously rotating up to 360°.

High-Temperature Slip Ring Composition

Different slip ring manufacturers use different materials to make the slip rings. Their focus is to come up with a slip ring that withstands high temperatures and still perform its function of ensuring a continuous, undisturbed, and accurate flow of information. What are the basics?

Most manufacturers use the process of infusing and coating. As you know, the slip ring has two main components that are the brush and the conductive surface. Manufacturers use metals that are highly resistant to heat and coat it with precious gold.

Why coat with gold?

Why the precious gold coat? With all the other alloys and coatings that a manufacturer can use, precious gold remains to be the best choice for many manufacturers. Why is that so? The following are the advantages of using an expensive gold coat:

1. Resistant to heat

With a melting point of 1064°C, it makes it a perfect jacket for the slip ring since no amount of heat can destroy it.

2. It is a poor conductor of heat

There is no loss of heat in the process of transmitting signals.

3. Resistant to corrosion

Many manufacturers want to come up with a slip ring that does not rust. The gold coating reduces corrosion. Hence, the slip ring works quietly without corrosion noise.

The high-temperature slip rings undergo much testing to make sure they serve their purpose. One such test is the vacuum test. Here manufacturers test the resistance of the slip rings under various temperature levels. They also check sound to noise ratio to make sure they are efficient enough.

Benefits of Using High-Temperature Slip Rings

A manufacturer whose operation requires high temperatures finds it convenient to use the slip ring. That’s because they have advantages over other slip rings. The following points explain what you gain by using the high-temperature slip rings:

Applicable under high temperatures

The making of high-temperature slip rings helps them work efficiently under extreme heat conditions. Depending on the type of high-temperature slip ring, it can withstand a temperature of up to 500°C, making it best for high heat environments.

It has a single circuit

Since it is of a single channel, it rotates 250 rotations per minute. Thus, it makes them efficient as they work without losing any heat or current during the transfer process.

It is durable

The precious gold coating eliminates the chances of corrosion. Thus, they last longer.

Make less noise during production

The brushes have a gold coat which makes them make less noise while in contact with conductive surfaces. Thus, they turn out suitable to use in quiet environments.

Cost-effective

The slip ring requires minimal maintenance since there is no damage due to extreme heat and corrosion.

Efficient

It serves the purpose of every slip ring. To transfer signals, data, and current swiftly and accurately without disturbance between rotating and stationary structures in many devices or machines.

How to Increase High-Temperature Slip Ring Durability

As much as the slip rings are suitable for use in extreme heat environments, continuous use can make them tear out and become inefficient. How do you increase their durability? Use the following methods.

  • Use it under moderate conditions. Temperatures between 80°C and 250°C sounds practical.
  • Use the slip rings in dry places to reduce corrosion due to moisture.
  • Keep them away from corrosive metals and alkali to avoid rusting of metallic parts.
  • Use installation illustrations to make sure you install the slip ring the right way.

Conclusion

Rotating machines and surfaces require a slip ring to assist in transferring a signal, data, or current. In extreme high-temperature conditions, a high-temperature slip ring comes in handy since manufacturers use high-quality materials to make it resistant to heat.
