SPM Instrument
Shock Pulse Transducers
40000, 42000 and 44000 series bearing transducers
- Part number
- 40000
- Brand
- SPM Instrument
Special transducers tuned to a 32 kHz resonance frequency to detect the shock waves generated by metal-to-metal contact on bearing surfaces. Permanent measuring point adapters, probe and quick-connector versions cover every mounting scenario.
Highlights
- Standard and non-standard adapters, versions with lock nut
- Glue-on adapters and mounting feet
- Probe (TRA-22/72/73/78) and quick-connector (TRA-30/70/74/79) versions
- Transducer Matching Unit (TMU) options
Repeatability in shock pulse measurement depends on reading the sensor from the same point under the same contact conditions every time. For this reason, permanent adapters or glue-on mounting feet are recommended at critical points; the hand probe is suitable only for quick checks.
