Factory-fitted 50 m PTFE-insulated, steel-braided coax retains high-frequency fidelity for remote control-room or offshore installations.

Hastelloy-C alloy resists aggressive chemicals, salt spray, and high-temperature corrosion.

DC–25 kHz captures both slow shaft deflection and high-frequency vibration; micron-level resolution with ≤ 1 % nonlinearity.

Survives up to 200 bar pressure, 100 g shock, and 30 g vibration; IP 67 sealing at tip protects against immersion.

Intrinsically-safe approvals allow direct mounting in classified zones when paired with certified signal conditioners.

Probe mounted on gearbox housing with 50 m cable to sheltered rack; detects gear-mesh sidebands and eccentricity before failure in harsh sea-spray conditions.

Submerged or buried pumps feed long-span cable back to dry control rooms; continuous eccentricity and vibration data extend seal and bearing life without field splices.

Hastelloy probe in corrosive headspace monitors shaft bow and high-frequency vibration; data drives automated ramp profiles to avoid blade rubs and weld fatigue.
