CSA Class I Div 1 Groups A B C D

IEC 60529 / CE / CENELEC

Ideal for applications where larger clearances or axial movements must be monitored.

Allows deep or hard-to-reach mounting positions without compromising tip access.

No factory cable; installers choose the exact cable length and connectors to suit their layout.

Captures slow deflection and high-frequency vibration (DC–20 kHz) with micron-level precision.

Lightweight yet durable, resisting industrial shock, vibration, and moderate chemical exposure.

Compatible with intrinsically-safe conditioners for classified locations.

Tracks 0–5 mm axial movement in agitator shafts; signals feed into PLC interlocks to prevent blade-to-wall contact.

Machine builders provide the bare-cable variant, enabling end-users to tailor cabling for custom panel layouts and reducing stock variations.

Aluminum housing tolerates splash zones; field-specified cable runs from submerged probe head to on-deck conditioners.
