External Shock Pulse Probe

Description

TRA-73 Hand-Held Probe – Precision Accessory for BearingChecker

The TRA-73 Hand-Held Probe is a high-precision accessory engineered for use with the BearingChecker instrument. Designed for accurate and reliable vibration measurements, it ensures dependable performance even in demanding industrial environments.

Accurate & Directional Measurements

• Built with directional sensitivity for precise readings

• Must be held in proper alignment with the bearing surface (±5° maximum deviation)

• Ensures consistent, repeatable accuracy across applications

Rugged Construction

• Spring-loaded tip for secure contact during measurements

• Durable chloroprene (neoprene) rubber sleeve withstands temperatures up to 110 °C (230 °F)

• Robust build for long-lasting durability in tough operating conditions

Optimized for Bearing Monitoring

• Measuring points should be placed directly on the bearing housing for optimal signal quality

• Strongest shock pulse signals are emitted from the loaded rolling interface region:

  • Radial loads: ±45° from load direction

  • Axial loads: full 360° coverage

• Geometry allows direct radiation of pulses within ±60° from the perpendicular rolling surface

Best Practices for Consistency

• Mark measuring points clearly (e.g., with SPM marker BEX-19) to ensure repeatable results

• Apply steady pressure until the rubber sleeve makes full surface contact

• Avoid placing the tip in cavities or fillets narrower than the probe tip, which may reduce accuracy
