ATEX Zone 1 (Ex ia IIC T6)

CSA Class I, Div 1, Groups A B C D

IEC 60529 / CE / CENELEC

Linear, high-resolution displacement over 0–2.5 mm with ≤ 1 % nonlinearity when paired with a matching conditioner.

Stainless-steel housing and hardened tip resist shock, vibration, pressure (100 bar), and temperatures up to +140 °C. PTFE-insulated, steel-braided cable withstands chemicals and abrasion.

Integral 10 m low-capacitance cable preserves full bandwidth and simplifies routing in large machinery rooms.

ATEX and CSA approvals allow installation in hazardous zones; pairs with remote conditioners for intrinsic-safety.

M6 × 0.5 thread fits ν-blocks or bearing brackets; fully compatible with IQS450/IQS452 conditioners and VM600 protection/monitoring cards.

Mounted on runner wall, capturing both slow thermal bow (DC) and high-frequency resonance. Data drives preventive maintenance on wicket gates and bearing seals.

Installed through a sealed port into a submerged pump. 10 m cable to topside VM600 cabinet enables continuous eccentricity monitoring in wet, high-pressure environments.
