Vibration-sensor adapter bracket for a pump retrofit

Published with the customer's permission.

  1. Mismatched interfaces: M8 / 76 mm on the housing, M5 / 30 mm on the sensor
  2. The sensor axis is offset +62 mm / +48 mm and rotated 17° to the measurement plane
  3. Steel compression sleeves close the 25 N·m preload metal-to-metal: the plastic does not creep
  4. Brass heat-set M5 inserts — the thread survives repeated sensor removal
  5. A Ø18 H7 steel precision bushing in the locating bore — wear and fit are not carried by the plastic
  6. Ribbed thermal break: contact with the hot (85 °C) housing is reduced to four 3 mm walls
  7. Truss layout: first natural frequency > 800 Hz — outside the 10–1000 Hz diagnostic band
