SONOTEC was founded in the beginning of 1991 by the physicists Dr. Santer zur Horst-Meyer and Hans-Joachim Münch and has been owner-managed since then. With currently more than 165 employees, today we are a growing technology company established on the market as a provider of specific solutions using ultrasonic measurement technologies. One of our specialties is the development and production of gages for nondestructive ultrasonic testing.

All our products are developed and produced in house – with SONOSCREEN ST10 and SONO FD-1 two extremely robust and reliable ultrasonic flaw detectors had been developed.

 Applications. Our flaw detectors can be used for all conventional ultrasonic tests such as weld inspections, wall thickness measurements and the detection of discontinuities, which includes invisible cracks, inclusions, voids and other discontinuities in metals, plastics, ceramics and composites.

Matching these two flaw detectors we offer you a wide range of SONOSCAN standard as well as customized probes.

Let’s have a closer look to both of them:

 SONOSCREEN ST10

 Advantages at a glance:

  • Great Performance and intuitive menu navigation
  • High performing square wave transmitter
  • High-resolution 8″ graphic display, 16:9 format
  • 5 ns resolution over the entire measurement range
  • Robust aluminum housing, IP66 certified
  • 2 GB internal memory for storing up to 60.000 A-scans plus device configuration
  • External data storage on USB flash drive

Save time – Intuitive menu, fast test-setup and editable database

Developed with the help of experienced material testing experts, the robust SONOSCREEN ST10 ultrasonic flaw detector unites high spec performance with user-orientation. A clearly-structured menu quickly guides the tester step by step through the test set-up. This helps to increase testing reliability and to save valuable testing time. By turning and pressing the rotary knobs, you can browse quickly through the menu. The complete menu tree is displayed in full text and the selected menu path is highlighted in red.

All parameters needing configuration are arranged logically one after the other. This ensures that all relevant parameters are set before testing begins. A useful database also helps to shorten the preparation time: the database already contains all SONOSCAN probes. Other probes are easy to add. The provided probe settings overview enables quick verification of the entered data. Selected calibration blocks are also stored to enable rapid distance calibration. Device setup, probe and material databases can be stored on a USB flash drive and transferred to other SONOSCREEN units.

Features and evaluation methods

Designed for rough applications, the ultrasonic flaw detector stands firm to extreme temperatures between -20 to 60 °C, with the large, high-resolution 8″ graphic display showing all measurement results at a glance. And the robust aluminum IP66 certified housing makes SONOSCREEN ST10 an ideal flaw detector in harsh environments.In addition the SONOSCREEN ST10 is equipped with the following features and evaluation methods:

 

  • Configurable display with up to 10 measurement values
  • Display of a measurement range up to 10 m in one A-scan
  • Editable database for materials, probes and setups
  • 400 V powerful square wave transmitter for high material penetration
  • 5 ns resolution over the entire measurement range (equivalent to 0.03 mm in 10 m steel)
  • 2 GB internal memory for storing up to 60 000 A-scans plus device configuration

Evaluation methods

  • Optional DAC/TCG, DGS (AVG) and AWS D1.1
  • DGS curves for single-element probes and sender/receiver probes
  • DAC evaluation with TCG z Single point modification of DAC curve
  • Up to 4 additional freely-positionable curves can be displayed for DGS and DAC (in 0.5 dB steps)
  • Amplitude evaluation according to AWS D1.1 z Comparison and envelope curve function

SONOWALL 70

 Advantages at a glance:

 

  • Corrosion module incl. grid – no manual sketches and data storage needed anymore
  • SONO-ID – Intelligent probe recognition including saved setups
  • 990g lightweight, carrying strap and flip screen for comfortable use
  • Upgrade to flaw detector

Upgrade to flaw detector

 The SONOWALL 70 allows two modes of operation. In addition to the numerous possible uses as a wall thickness gage, it can also be expanded to a flaw detector by means of a software update. Thus, the ultrasonic measuring device is also suitable for checking weld seams and detects invisible cracks, inclusions, discontinuities, blowholes and other discontinuities in metals, plastics, ceramics and composite materials.
