Configured for radial vibration and axial position measurement in hazardous areas, the Bently Nevada 330104-08-14-10-02-05 (3300 XL 8 mm Proximity Probe) provides direct physical displacement sensing via armored eddy-current transduction.

Physical & Hazardous Area Data

Eddy-Current Probe Scaling and Intrinsic Safety Barriers

The probe utilizes eddy-current induction for non-contact displacement measurement. Accurate scaling requires calibration against AISI 4140 steel targets. In ATEX/IECEx installations, the probe must interface with certified intrinsically safe (Ex i) galvanic isolators or zener barriers to limit energy transfer into the hazardous zone. Gap voltage validation must confirm a stable -10 VDC output at the monitor terminals under static conditions to ensure operation within the linear range.

Technical Inquiries

Q: Can this armored probe be used without a barrier in a safe area?

A: Yes. When installed outside classified hazardous locations, the probe operates directly with standard 3300 XL monitor modules without requiring intrinsic safety barriers.

Q: Does the armor affect the linear range?

A: No. The stainless-steel armor protects the coaxial cable from mechanical abrasion but does not alter the electromagnetic field or linear measurement characteristics.

Q: What is the maximum permissible cable length?

A: The total probe plus extension cable length must not exceed 9.1 meters (30 feet) to maintain system impedance matching and signal integrity.

Field Installation Guidelines

Install the probe perpendicular to the target surface. Engage a minimum of 5 full threads into the machine case to ensure vibration resistance. Route the armored cable with a minimum bend radius of 75 mm (3 inches) to prevent dielectric stress. Terminate the cable shield at the monitor ground terminal only. In hazardous areas, verify barrier compatibility and wiring parameters per the certified safety drawing.
