Piezo tubes come in various types, with each one being suited to a different application. Supplier-related buyers should know these types so they can stock or bulk order the ones that customers most often ask for. Below, then, is a rundown of the main types of piezo tubes.
This is one of the most basic types. It has only one layer of piezoceramic material. The simple design means it’s not as powerful as the others. However, it still performs well in basic applications, such as medical devices and ultrasonic cleaners.
As the name suggests, this type has several layers of piezoceramic material. Each layer increases the tube's output and efficiency. That makes it ideal for high-demand applications such as industrial ultrasonic transducers or high-precision pumps.
These tubes are made from piezoelectric polymers like PVDF. They offer flexibility that ceramics can’t match. That makes them great for wearable devices or any application that demands light, bendy components. Also, the way they are built means they are less likely to crack or break under stress than ceramic piezo tubes.
These tubes have a layer of piezoelectric material applied to a different substrate. That could be ceramic or metal. The coating provides good performance while still being able to bond well with other materials. It also allows the tube to be stronger and less prone to breaking. Thus, it suits applications that want a strong piezo component, such as sensors in harsh environments.
This type consists of two different piezoelectric materials bonded together in a single tube. When voltage is applied, the two materials expand at different rates. That causes them to bend. It makes the tube very useful in precision actuators or optical systems where tiny movements are needed.
It’s important for buyers to know the specs and upkeep requirements of piezo tubes. Then, they can provide the right information to end users or look after the components themselves. Below, then, are some of the key specs to consider and maintenance requirements for buyers to stock or bulk order piezo tubes.
The main key specifications that buyers should consider are listed below.
Below is a list of five key upkeep requirements buyers should keep in mind.
The commercial value of piezo tubes varies a lot. Where the tube will be used the most and what kind of are usually the main determining factors of their value. So, below is a detailed look at the business worth of these tubes in different materials and application types.
The type of material a piezo tube is made of affects its value. Buyer-related professionals should, therefore, keep this in mind when selecting models for their stocks. Here are some common materials and how much value they bring.
Which industry the buyer uses the piezo tubes in also affects their commercial value. Below are the most common industry applications and their associated commercial values.
The demand for piezo tubes drives their commercial value. Likewise, so does the supply. Demand can increase or decrease when a particular industry needs certain tubes more or less often. Supply chain issues can also impact availability. When that happens, prices go up to meet the demand, putting an end to the value the products had.
Buyers should consider the key factors below to select the right piezo tubes for the market they intend to serve. They should also stock various types to ensure they cater to all the end users who might buy from them. So, here are the key selection factors to keep in mind.
It is the first factor to consider. Buyer specialists should think about the material that will suit the end user's needs the most. For instance, medical and industrial clients use piezoelectric ceramics the most. On the other hand, electronics and wearable clients prefer piezoelectric polymers.
The tube size affects performance and applicability. Buyers should therefore ensure that the tube's diameter and length match the requirements of their end users. Users usually need small tubes with short lengths for consumer electronics. For industrial tasks, the user often needs larger, longer ones.
Buyers should assess key electrical features like capacitance and dielectric constant. These features affect how the tube will perform. Likewise, they are important to end users who want the components to work well. So, to ensure they cater to this market, buyers should stock piezo tubes with various electrical characteristics.
Buyers should get different piezo tubes for the several common applications. For instance, ultrasonic cleaners, actuator systems, or 3D printers. They should also get several pitches to ensure they meet the end users' load requirements.
Buyers should look for piezo tubes that come in secure packages. The packages should protect the tubes from break or cracking during transport, handling, or storage. Also, the packaging should keep the tubes free of dust and environmental moisture.
A1. Yes, they do. The different thicknesses help to improve the tube’s function and flexibility. Also, that’s why they are used in different applications. For instance, the standard piezo tubes often have a thickness of around 0.5 mm. However, specialty ones can have thicknesses of up to 5 mm.
A2. It largely depends on the materials and specific use, though. The tubes for medical applications typically last for more than 10 years. However, those used in more stressful environments, like industrial ones, usually only last about 5 years. Wear and tear from heavy use is the main reason for this shorter lifespan.
A3. Yes, they are. That’s why they are commonly used in different sensing applications. The shocks can damage some of the components. However, the ceramic and polymer materials that make the piezo tube are very strong and sturdy. So, they can bear environmental vibrations and mechanical shocks with ease.
A4. Yes, they can. Many piezo tubes work together to improve output power or precision. It allows for more complex applications where strength or accuracy needs to be boosted. Using more than one in a system increases the versatility of piezo tubes, making them suitable for more demanding applications.
A5. Fortunately, no. Piezo tubes are actually quite energy efficient. That’s because they don't need a lot of voltage to operate. They typically work well with standard electric fields. It makes them a great choice for low-power applications that need to be sustainable.
