Tester of Stress Concentration TSC-8M-4

From 2 to 4 measuring channels

TSC is a system for measuring, recording and processing of diagnostic data about stressed-strained state of equipment and structures using the metal magnetic memory method.

Rosstandart Certificate RU.C.34.003.A No.42683.

The TSC-type devices are manufactured serially. By the operation principle they are specialized multi-channel flux-gate magnetometers. The Hp magnetic field intensity is calibrated on instruments' scales in A/m (Ampere/meter). The length of the recorded sensor movement is calibrated in mm (millimeters).

The TSC-type devices are unique means of measurement although there are a lot of various gages of magnetic field intensity (magnetometers) based on flux-gate transducers in Russia and abroad. Their uniqueness is both in their functional designation (detection of stress concentration zones, which are the main sources of equipment damaging) and in their structural specific features, marking them out significantly among the known magnetometers.

The distinctive features of TSC-type devices are:

  • Multi-channel operation
  • Scanning devices (18 types) allowing reading the values of field intensity and sensor movement length at a speed up to 0,5 m/sec (all scanning devices are protected by Russian and International patents)
  • Software for automatic processing of results directly on test objects
  • Flash-memory for recording the results of object inspection and possibility to transfer the data to IBM-compatible computers
  • Possibility to record inspection parameters with a specified frequency at a time unit ("timer" mode), which allows to execute inspection at products movement relative to sensors (inspection of rotating elements, moving ropes and cables, inspection of rails at flaw detector car movement, etc.)
  • "MMM-System" software for computer processing of inspection results in Windows 7/8/10

The TSC-8M-4 device has the following structural and functional distinctive features:

  • From 2 to 4 flux-gate transducers
  • Microprocessor 16 bit
  • RAM 1 Mb
  • 8 Mb flash-memory for recording of inspection results on object during 8 days without transferring the data to the computer
  • Special keyboard with 14 functional keys
  • Liquid-crystal display with resolution of 320х240 pixels for reflection of graphical information directly at equipment inspection
  • Dimensions 165х83х32 mm
  • Weight including storage batteries 0,4 kg
  • Power supply from built-in storage batteries DC 5В
