Using the latest developments in amplifier and pulser technology to deliver higher levels of near surface resolution and penetrating power the Railscan 125 Ultrasonic Flaw Detector has been developed and designed specifically for Rail Testing within the Rail Infrastructure NDT market.
Designed specifically for Rail Testing, the Railscan 125R rises to the demanding challenges set by this environment for NDT and it’s operators.
Network Rail (UK) procedure and approval
Narrow Band amplifiers 2 and 5 MHz; G1 +ve trigger, G2 -ve trigger, (0.6 second delay for monitoring rail bottom depth).
Long Battery Life: Latest Li-Ion technology 10-16 hours (brightness dependant) Quick re-charge in 3-4 hours
Walking Stick Compatibility: Sperry walking stick. Others (e.g., NRS bi-directional walking stick)
Single-shot PRF for high speed multiplexing
RS232 & USB outputs: Supporting custom software systems, (e.g. Sperry palmtop with GPS
