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

IEC 60529 / CE / CENELEC compliant

Captures slow shaft deflection and high-frequency vibration (up to 25 kHz) with micron-level accuracy.

Withstands up to 200 bar pressure, extreme temperatures, and severe shock/vibration.

Factory-fitted, PTFE-insulated stainless braid ensures ruggedness and signal integrity without field wiring.

Durable against corrosion, moisture, and mechanical wear—ideal for harsh and splash zones.

Operates reliably in steam-turbine and other high-heat applications up to +150 °C.

Intrinsically safe approvals permit direct mounting in explosive atmospheres when paired with certified conditioners.

Extended 25 kHz bandwidth captures gear-mesh harmonics for early fault detection in high-rpm gearbox trains.

Heavy-duty shock resistance enables reliable displacement sensing on pulverizer shafts subjected to intermittent impacts.

Stainless-steel probe and cable braid resist salt spray; integrates with VM600/IQS cabinets for continuous eccentricity and vibration protection on unmanned platforms.

Hastelloy probe in corrosive headspace monitors shaft bow and high-frequency vibration; data drives automated ramp profiles to avoid blade rubs and weld fatigue.
