ATEX Zone 1 (Ex ia IIC T6)

CSA Class I Div 1 Groups A B C D

IEC 60529 / CE / CENELEC

60 mm probe body for recessed or deep-mount positions, ensuring tip access to the target surface.

No factory-fitted cable; installers specify PTFE-insulated, shielded coax length and connector type on-site.

Minimizes probe mass to avoid influencing delicate shaft dynamics or bearing loads.

Wideband, High-Resolution Measurement

Captures both slow thermal drift and high-frequency vibration (up to 20 kHz) without external filters, with micron-level resolution.

Designed for extreme shock, vibration, temperature, and pressure; IP 65 protection at the sensing tip.

Intrinsically safe approvals (with appropriate conditioners) allow direct installation in classified areas.

The 60 mm body reaches recessed journal bearings; user-supplied cable runs back to a remote VM600 rack. Continuous eccentricity and vibration data prevent misalignment and rubs.

Aluminum housing and configurable cabling allow integration into bespoke gearbox assemblies where space and mass constraints are critical.

Mounted on draft-tube shafts; custom-length cable routes through the dam structure to conditioners in a dry control gallery, monitoring slow deflection and resonance.
