Inspection systems

New universal ultrasonic multichannel inspection system of series UPNК with high-speed data processing

Flaw detector multichannel UPNК

New inspection system represents universal modular flaw detector/thickness gauge with the independent parallel channels, constructed on essentially new high-speed architecture of the channel. Having left from the predecessor a principle of construction of the system, new UPNК v2.0 it is constructed on use of two high-efficiency industrial computers with panel LCD monitors - one for input of signals in the real time, the second - for the general management of system, the data backup, communication with other devices of a manufacturing computer network. Item inspection systems consists of two industrial 19 cases Rittal, with established - multichannel flaw detector, a power unit, the industrial block of an uninterrupted power, 2 industrial computers with panel LCD monitors and the printer. The third industrial case - is intended for inspection system of automated management by drives and devices of mechanisation process of the testing (including devices of loading / of an unloading of products).

Differential characteristic

  • Independence of all channels and use of 2 computers: processings and managements of work, allows to provide high-speed work of system and to realise various modes of processing of signals in each channel with frequency of parcels to 10 КHz;
  • Possibility of a combination a quality monitoring: simultaneous search defects and definition of their depth occurrence, measurements of a thickness and the geometrical sizes of defects with the water temperature testing in immersion to a bath; the frequency range of the channel - from 500 KHz to 25 MHz
  • The frequency range of the channel - оup to 500 КHz to 25 MHz;
  • Preservation reports of the testing products in the form database file, allows to introduce paperless technology of the testing;
  • Use of network possibilities Windows NT/2000, does possible remote monitoring of a site of the testing and integration of inspection system into uniform manufacturing system of quality;
  • Realisation any ways of the testing is possible: immersion (with synchronization from a superficial signal), the single/dual echo-method, shadow or mirror-shadow methods.

Basic field of utilization

    The automated ultrasonic testing of products
  • in mechanical engineering (the entrance testing of bar, the testing of shaft, cylinders)
  • in an aircraft industry (the testing of disks, shaft and etc.
  • in metallurgy (the testing of forging, moulding, including from aluminium, the titan, etc.)
  • on a railway transportation (the testing of wheel pairs and etc.)
  • in trumpet manufacture (seamless pipes of an oil and boiler assortment, longitudinal pipes for oil and gas grow)
  • in the nuclear industry (thin-walled seamless pipes, welded jointss of tubes, the testing of a thickness of walls of pipes from 0,2 mm, the testing of extent of a contacting-butt welded seam of thin-walled tubes of small diameter and etc.)
  • by manufacture of products from pig-iron (the testing rolling mill and etc.)
