Ultrasound Testing Devices

Ultrasound Testing Devices – An Overview

Many factories use timely preventive maintenance to minimize machine failures, scale plant availability and save costs on energy. 

Multipurpose ultrasonic testing devices let you perform many of these operations efficiently and promptly. 

With ultrasonic devices in effect, you can detect leakages in the air or vacuum systems, inspect bearings, check on how the valves function, and analyze the electrical partial discharges. 

In this blog, let’s know everything about Ultrasound testing devices and how Ocean stands out in delivering the best devices to ensure your plant functions remain reliable and smooth.

What does Ultrasound Testing mean?

Ultrasound testing refers to the process of measuring and recording ultrasound waves. 

The waves are said to be ultrasound if their frequencies exceed 20KHz. 

Through ultrasound testing, you analyze these waves that propagate along the solid and liquid medium to ultimately determine the inaccuracies due to air/gas leakages and friction from bearings.  

Many industries including Aluminium, steel, oil and gas, manufacturing, automotive, aerospace, and power, utilize this testing method to enhance the overall functioning of the plant. 

Let’s dig further into the devices used for Ultrasound Testing.

How does this process work?

The testing requires an ultrasound transducer— a device that transforms the ultrasound energy into electrical energy. 

Diagnostic equipment aids in the inspection of the machine to ensure the plant works efficiently. 

Here are the two types of transducers based on their uses:

  • Air-borne transducers: 

Airborne inspection is usually performed to identify the air and gas leakages that occur in critical industries. 

These leakages not only degrade the plant’s efficiency but also challenge personal protection due to the toxic emissions. 

In this type of testing, the transducer doesn’t have to be in contact, and the inspection can occur even at a 15-meter distance with sensors such as parabolic sensors.

Air/gas leakage generally produces ultrasound noise with turbulence in the area of leakage.

The sensor generates adequate noise levels in the diagnostic instruments to let you evaluate the annual cost loss.

The SONOTEC leak calculator can help to make this analysis based on the data the manufacturer provides. 

  • Structure-borne transducers:

With structure-borne inspection, you can understand the irregularities that bear damages and malfunction in the steam trap in the industries. 

The critical rotating machinery should function properly to improve the lifetime efficiency of the machine components. 

This testing involves placing the transducer on the surface of the component. 

Irregularities present in the roller bearing cause friction between components and the sensors to produce ultrasound noise.

The sensor thus builds a spectrum that remains proportional to the abnormalities in the system. 

Significant Features of Ultrasound analysis 

The early detection of faults in the bearing and appropriate diagnosis are essential to monitoring the conditions of the machine you use.

With high sensitivity, you can detect even the smallest abnormalities that occur in the machines. 

This method is the best and most accurate compared to any other non-destructive method since it assesses the effect of internal defects and analyzes even minor gas/air leakages. 

It also predicts the extent of leakages based on the data from the manufacturer. 

The testing method is non-hazardous to any other functioning of the plant, and the surrounding workforce, keeping the equipment and materials undisturbed. 

The portable and completely automated operations produce immediate results, while you can also deploy corrective measures right after the inspection. 

Core Industrial applications of ultrasound examination

Ultrasound analysis involves a non-destructive examination process which is ideal to locate the leaks and defects in the machine without causing any damage to it.

Periodic ultrasound analysis can also be helpful to test the condition of bearing health, manage lubricant, and inspect steam traps and compressor air leakage. 

It offers the following industry-specific applications: 

1. Lubrication management

Ultrasound lubricates the machine bearings to deploy condition-based maintenance instead of a time-based maintenance process.

2. Keep a track of the bearings & Steam trap condition

The ultrasound keeps track of the health of the bearing and steam trap regularly. This helps to plan maintenance which triggers plant reliability. 

3. Air and gas leakage detection

Ultrasound inspects and records the gas or air leakages at every compressed pipeline joint. It also improves the entire plant’s efficiency and offers cost-effectiveness.
