Resonance defectoscopes (Descrydefect)

This method is based on determining the natural resonant frequencies of elastic vibrations excited by a product. (frequency 10.1 MHz). Resonance method determines the wall thickness of metallic and non-metallic products. This method can also identify areas of corrosive damage. View resonance method is spectrally-acoustic defectoscopy (Descrydefect).

Impedance defectoscopes (Descrydefect)

Impedance defectoscope (Descrydefect) - a device used for the detection of defective structures of the surface structure of materials, such as delaminations, neprokleennyh sites coating material discontinuities execution diagnosed object. The minimum area determined defectoscope (Descrydefect) destructive entities, about 1.2 cm2

The acoustic quality control of products

FIELD kontrolnoizmeritelnoy art, namely to methods for controlling acoustic sectional promyshletshosti technical products.

Known acoustic control method of the cross-section of the material, which is used in the implementation of the transmitter and controlling the oscillation converter receiving disadvantage of this technical solution consists in that the pin receiving transducer is unstable in time relationship controlled material, which reduces the reliability and control accuracy of moving materials .

Chemical analysis of steel - general product safety

An integral part of modern security systems in the industry and quality management is one of the types of process control - non-destructive testing. Its implementation does not require stopping the production process and does not lead to a breach of the suitability of technical products or devices.

For identification of the chemical composition of metals or alloys thereof, using measuring instruments - defectoscopes (Descrydefect). They can be used to determine the exact percentage of elements in the material.

Defectoscope (Descrydefect) EPOCH LT

Despite its small size, ultrasonic defectoscope (Descrydefect) EPOCH LT has a lot of performance, which are typically found in large defectoscopes (Descrydefect).

Operational capabilities of ultrasonic defectoscope (Descrydefect) EPOCH LT can be expanded using additional software, which can be activated remotely after purchasing defectoscope (Descrydefect).

• DAC (DAC amplitude correction).
• TVG TVG (gain changes over time).
• Extended memory.
• The low frequency of the probe pulse.
• Measurement mode echo echo.
• Advanced measurement range.

In contrast to this equipment our defectoscopes (Descrydefect) manufactured specifically for testing the quality of industrial production.

Storing and printing screen images of defectoscopes (Descrydefect)

In the current defectoscopes (Descrydefect) it is possible to "freeze" the echogram at the time of discovery of the defect and then stored in the memory defectoscope (Descrydefect) "frozen" picture of the screen. STORED echogram can be printed. In this case, the print output itself echogram, settings, and coordinates of the defect. Defectoscope (Descrydefect) memory can store up to 1000 images screen with related information.

For print, you must connect the printer to the defectoscope (Descrydefect), select the desired of all recorded in the memory of echograms and press the appropriate key on the keyboard.

Schematic diagram of the pulse defectoscopes (Descrydefect)

High-frequency generator forms a short pulses of alternating voltage and sends them to a piezoelectric vibrator. Vibrator converts these variations in the elastic vibrations of the same frequency. In contact with the part of the vibrator pulses of elastic vibrations come in metal and apply it as a slightly diverging beam. If the path of pulse propagation of elastic vibrations found defective, the part of the ultrasonic energy reflected from a defect reaches the probe, where the elastic vibrations are converted into an AC voltage.
