Ultrasound is the earliest method to assess the condition of your assets. This advantage allows you to minimize the cost of troubleshooting and schedule repairs well in advance of failure.

Malfunctions such as insufficient grease in bearings, or leaks of compressed air or gas cannot be detected without the use of special ultrasonic equipment.

However, not all ultrasonic devices have the same sensitivity and can operate at different frequencies, and often the lack of proper training and proper maintenance system reduces the effectiveness of the use of ultrasonic devices.

SDT has been developing and manufacturing condition monitoring instruments for more than 45 years, has its own training center for technical specialists, and also helps the company’s management organize an optimal maintenance system to achieve the most elective result in condition monitoring.

SDT ultrasonic detectors are able to capture various production noise, which allows you to find/detect faults and analyze them. Other diagnostic medical sonography methods often do not allow finding these types of faults, which makes SDT ultrasonic analyzers indispensable in the enterprise. Ultrasound can detect faults much earlier than any other condition monitoring technology.

Ultrasound generated in a plant is often caused by friction, shock, and turbulence. These phenomena are very well captured in the ultrasonic region.

Ultrasonic detectors allow you to detect, measure and analyze friction and shock in mechanical systems.

Turbulent flow occurs when compressed air, vacuum or gas leaks.

Also, turbulent flow occurs when there are malfunctions in shut-off valves or steam traps.

Separately, two more areas of application for ultrasonic detectors can be noted: early diagnostics of electrical equipment and assessment of the tightness of closed volumes.

Diagnostics of electrical equipment is based on the measurement of air ionization at the time of failure, such as corona or partial discharges.

The tightness of closed volumes is carried out in two ways: by creating excess / discharged pressure in the volume or using special ultrasonic generators that allow this type of diagnostics to be carried out without pressure.

Versatility

The versatility of ultrasound is unlike any other condition monitoring technology. Ultrasonic detectors allow diagnosing the faults described above using various sensors.

 

Ultrasound diagnostics

Ultrasound  is a study of organs and tissues using ultrasonic “waves”. Passing through tissues of different density, or rather through the boundaries between different tissues, ultrasound is reflected from them in different ways.

The ultrasound method is simple and affordable, has no contraindications. Ultrasound can be used repeatedly during the entire period of observation of the patient for several months or years. Moreover, the study can be repeated several times within one day, if the clinical situation requires it. Ultrasound is the method of choice for diagnosing pathological conditions during pregnancy.

Ultrasound is a widely used by diagnostic medical sonographers. It does not expose the patient to radiation exposure and is considered harmless. However, ultrasound has a number of limitations. The method is not standardized, and the quality of the study depends on the equipment used for the study and the qualifications of the doctor. An additional limitation for ultrasound is excess weight and / or flatulence, which interferes with the conduction of ultrasound waves.

Opportunities and advantages of the ultrasound method

Ultrasound is the standard diagnostic method used for screening. In such situations, when the patient has no diseases and complaints yet, it is ultrasound that should be used for early preclinical diagnosis. In the presence of an already known pathology, it is better to choose CT or MRI as methods for clarifying diagnosis.

The areas of application of ultrasound in medicine are extremely wide. For diagnostic purposes, it is used to detect diseases of the abdominal organs and kidneys, pelvic organs, thyroid gland, mammary glands, heart, blood vessels, various parts of the spine, joints, in obstetric and pediatric practice. Ultrasound is also used as a method for diagnosing emergency conditions requiring surgical intervention, such as acute cholecystitis, acute pancreatitis, vascular thrombosis, etc.

Training

Examination of the abdominal organs is carried out on an empty stomach (the previous meal is not earlier than 6-8 hours before the examination), in the morning. Legumes, raw vegetables, black bread, milk should be excluded from the diet for 1-2 days. With a tendency to gas formation, it is recommended to take activated charcoal 1 tablet 3 times a day, other enterosorbents, festal. If the patient has diabetes, a light breakfast (warm tea, dried white bread) is allowed 4 hours before the examination.

A transabdominal pelvic exam (bladder, uterus, or prostate) requires a full bladder. It is recommended to refrain from urinating for 3 hours before the study or to take 300-500 ml of water 1 hour before the study. When conducting an intracavitary examination of the pelvic organs (bladder, uterus or prostate gland), through the vagina in women – TVUS or through the rectum in men – TRUS, on the contrary, it is necessary to empty the bladder.

Ultrasound examinations of the heart, blood vessels, thyroid gland, spine, joints do not require special training.
