Specials are developed for specific applications. Housing designs, ultrasonic properties, element configurations, resistance to certain environmental conditions are specific for these kind of probes.
These probes are used for several applications. You can think of LLT-tandems for detection of vertical defects or the ADEPT or DELTA tandem for sizing of IGSCC.
Tube / Bore inspections
Pipe-probes are often used for inspection of bolts or heat exchangers. These can be configured for wall thickness measurements, weld inspection or multi-functional inspections.
High Temperature / Radiation resistance
Probes can be manufactured for use at temperatures up to 250ºC or for resistance up to 108 Rad.
Deep water testing
By following a special production procedure probes can be made pressure resistant up to 50 Bar (500m depth).
