Beam Interrupt Probe Typical Applications

• Fan stages where the axial motion exceeds the capability of the typical line probe.
• Measures both LE and Trailing edge of the blade.
• HCF investigations that require highly accurate stress conversions for modes with high modal gradients such as low aspect ratio tip modes.
• HCF investigations that require knowledge of the axial and tangential components of vibration.
• Untwist measurements.

Beam Interrupt Probe Mechanical Characteristics

• Separate transmit and receive probes.
• Probes are located ahead and behind the stage being measured.
• Single transmit fiber.
• Single or multiple receive fibers.
• Probe contains a mirror or prism to direct beam.
• Unpurged configuration available for low temperature environment.

Miniature Beam Interrupt Probe Mechanical Characteristics

• Separate transmit and receive probes.
• ~0.060" OD probe head.
• Probes are located ahead and behind the stage being measured.
• Single transmit fiber.
• Single receive fiber.
• Probe contains prism fabricated in the GRIN lens to direct beam.
