50 m integral cable lets you position control cabinets far from rotating machinery—ideal for remote pump houses, large turbines, or offshore platforms.

Hastelloy-C body withstands acidic, salt-laden, or high-temperature environments without degrading.

DC–20 kHz response captures both slow shaft deflections and high-frequency vibration with micron-level resolution.

Corrosion-resistant housing and long cable span suit tidal or platform installations—e.g., seawater-cooled compressors or oil-and-gas skids.

Place probes on high-speed journal bearings; long cable allows control rack to be up in a turbine gallery, away from vibration and heat.

Hastelloy body resists aggressive chemistries; cable routes through safe-area junction boxes to intrinsic-safe conditioners.
