The SPG 3 ultrasonic rail testing system is used to inspect railroad rails.

The SPG 3 testing system contains a custom built probe housing for 5 dual-element probes with angles set to 70°, 38°, 0°, -38° and -70°. The probes can either be activated all at once or individually with the distribution box.

The probe block is designed to be suspended in double gimbals to follow the contour of the rail. It can be raised by means of a Bowden wire. The rollers are designed to enable both rolling on rails as well as on the ground.

The SPG 3 can be utilized with various portable ultrasonic flaw detection instruments, such as the USM 35X.

The SPG 2 ultrasonic rail testing system is used to inspect railroad rails.

The SPG 2 testing system is equipped with 3 dual-element probes with angles set to 70° and -70° in one block and 0° in a second block. The probes can either be activated all at once or individually with the distribution box.

The two-probe blocks are designed to be suspended in double gimbals to follow the contour of the rail. They can be raised by means of a Bowden wires. The rollers are designed to enable both rolling on rails as well as on the ground.

The SPG 2 can be utilized with various portable ultrasonic flaw detection instruments, such as the USM 35X.

The tandem rig STH 1 is an ultrasonic rail testing system used to inspect rail welds (flash butt welds, alumino thermic welds) for flaws perpendicular to the rail surface.

The tandem rig contains probe holders for two 45° angle beam probes which moves in opposite directions. One is operated as transmitter and the other as receiver probe.

The tandem rig contains four magnets, which fix the rig during the tandem test.

The STH 1 can be utilized with various portable ultrasonic flaw detection instruments, such as the USM 35X.
