Field-installable PTFE-insulated coax up to 5 m allows optimal routing and connector choice.

Aluminum housing reduces mass on sensitive shafts or small turbine bearings.

DC – 20 kHz covers slow thermal deflection and high-frequency vibration without external filters.

High shock, vibration, pressure, and temperature tolerance ensure reliability in extreme conditions.

Intrinsically safe approvals (ATEX, CSA) enable direct mounting in classified areas with appropriate conditioners.

≤ 1 % linearity delivers accurate shaft-centerline and vibration data for protection and diagnosis.

Field-fit cable variant ideal for retrofitting long runs in pump houses or generators where panel-to-probe distance varies.

Aluminum probe reduces added mass in small steam or gas turbine journal bearing applications, feeding IQS450 conditioners and VM600 MPC4 for eccentricity protection.

Installed on high-pressure (up to 100 bar) pump housings in chemical plants; user-supplied cable runs to safe-area conditioners to detect cavitation and misalignment.
