This is a family of transducers protected, separate emission / reception angle piece or mainly used in Europe to frequency standards and different diameter translators used in the USA. We find these frequency specifications and diameter in many donor procedures and specifications of order or European standards. Sofranel, through its long experience in Non Destructive Testing and Ultrasound in particular, has developed its own line of translators using standard components according to European habits. These translators are shown below and you can also find them in the pages of specific families. Due to the integrated manufacturing, the prices quoted for these translators are very competitive, feel free to contact us.
applications:
- Normal incidence flaw detection
- Detection of defects in welds
- Control plates, billets, bars, forgings.
- Search imperfections in the metal sheets, weld inspection, ...
- Control axles and shafts (long play) by using the end of the prisms.

Transducers rights transmitting / receiving separate
Translators transmission / reception separate consist of two piezo-electric elements inserted in the same housing and separated by an acoustic partition. One element transmits longitudinal waves; the other member receives the reflected waves in the material.
Benefits:
- Improve the resolution as the input surface
- Eliminate duplication of delay line echoes in the case of high temperature applications
- Reduce the input noise on rough surfaces
- Allow pseudo-focusing effect
Applications:
- Measures residual thicknesses on corroded surfaces
- Corrosion monitoring and erosion
- Detection of craters and pinholes
- Detection of porosity, inclusions, cracks in castings and forgings

Monobloc angle transducers
The angle probes are used to generate shear waves at oblique incidence in the controlled material. This control technique is used in particular for inspection of welds. Monoblock translators have the advantage of a better grip and a reduced size of the housing to approach closer to the weld bead.
These new angle probes exist in frequency 2 MHz or 4 MHz with angles refracted in the steel of 38 °, 45 °, 60 °, 70 °. The housings are available with LEMO connectors 00 rear output (top exit option). A color coding on the top surface allows a quick recognition of the nominal frequency translator (4MHz: blue; 2MHz: yellow). These translators come with individual characterization sheet specifying the terms of characterization and results: sensitivity, bandwidth, center frequency, etc ...
These translators exist piezo-composite version for 4 MHz nominal frequency.
