Diese im Innern von Rohren rotierenden Prüfgeräte sind gut geeignet für die Rohrprüfung in der Petrochemie und in gewissen Anlagenteilen von Kraftwerken. Sie tasten die Innenseite von Rohren mit einem Ultraschallbündel spiralig ab, woduch die gesamte Länge des Rohrs geprüft wird. IRIS-Prüfköpfe arbeiten im Impuls-Echomodus und messen Wanddicke, Wanddickenreduzierung und Fehlerausrichtung in einem Innendurchmesserbereich von 0,5 Zoll bis 3 Zoll.
Various components are necessary to "build" an IRIS probe. The components are interchangeable and must be chosen according to the tube dimensions.
To build an IRIS probe, the following components are necessary:

IRIS turbines are propelled by water pressure to make them rotate at approximately 40 r/s. They include a 45° angled mirror that deflects the ultrasonic beam towards the tube wall.

IRIS probe cables have two functions: they supply the water pressure required by the turbine; and they carry the ultrasonic signal with the use of a small coaxial cable. The coaxial cable has a Microdot connector on the probe end and a BNC connector on the instrument / pump end. The water is supplied by the pump through a quick-connect 1/8 in. brass fitting.
