ATEX Zone 1 (Ex ia IIC T6), CSA Class I Div 1 Groups A B C D, IEC 60529/CE/CENELE

Short 36 mm body ideal for tight or recessed mounting locations.

No factory-fitted cable lets installers choose exact length and connector type on site.

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

Durable against shock, vibration, moisture and moderate chemical exposure.

Intrinsically safe when paired with approved conditioners, suitable for explosive atmospheres.

Recessed bearing pedestals often require short-body probes; user-run cable connects probe to an IQS-series conditioner, feeding VM600 protection cards for eccentricity trip logic.

Probe sits close to impeller shroud in tight casing; field-selected cable routes back to DCS-integrated conditioners to detect rubs or thrust shifts.

Limited mounting space inside draft-tube housings calls for a compact probe; cable runs through the dam structure to a dry-area monitoring rack, capturing both DC deflection and high-frequency
