Insis-EX

INSIS-EX is a veritable swiss knife of eddy current testing. There is little that it cannot do.

Advanced simultaneous multifrequency Eddy Current Test System for In-service inspection of heat exchangers and steam generators Remote Field Eddy Current Tests for ferromagnetic tubes General purpose static eddy current tests Rotating probe / dynamic tests Conductivity and Coating thickness measurement

Overview

INSIS-EX is a powerful leading-edge multi-frequency multichannel eddy current test system ideally suited for manual or automatic in-service inspection of steam generator / heat exchanger / BOP tubes.

Up to four frequencies can be used simultaneously for testing with up to 8 differential and absolute channels at very high sampling rates. Multiplexing extends the capability to up to 256 channels at 128 test frequecies.

Up to 4 probes/coils can be used with the system which is compatible with bridge, send-receive, rotating or array probes, making it extremely versatile. Remote field eddy current inspection is supported through a compact external amplifier.

Software includes data acquisition, storage, automatic analysis, tubesheet mapper, history compare and reporting. It optionally supports probe pusher and robotic manipulators for use in hazardous areas. TCP/IP servers accept connects from remote PCs on Internet or Intranet over ethernet.
