3. Product Description

The 330104‑00‑06‑50‑02‑00 proximity probe is engineered to provide accurate displacement and vibration measurements on large spinning shafts without making physical contact. It operates by generating a high‑frequency electromagnetic field at the probe tip. When a conductive target such as a rotating shaft moves into this field, eddy currents are induced within the target surface. These induced currents alter the probe’s impedance, which is translated into a precise voltage signal proportional to displacement.

This model’s large 50 mm probe diameter allows it to interact effectively with large equipment targets, and the extended 135 mm housing provides installation flexibility where space is available. The robust stainless steel body ensures physical strength and resistance to corrosion, while the high‑temperature PPS polymer tip retains accuracy in elevated operational conditions. The reinforced cable and industrial connector ensure that signal integrity is maintained even under high vibration and mechanical stress.

4. Applications

The 330104‑00‑06‑50‑02‑00 is widely used in industries where large rotating equipment must be monitored for both performance and safety:

• Steam turbines and electric generators in power plants
• Large centrifugal, axial, and reciprocating compressors
• Heavy industrial pumps in oil, gas, water, and chemical industries
• Massive motors and driven equipment under heavy load
• Gearboxes and large transmission systems
• Turbo machinery such as blowers and vacuum pumps
• Refineries and petrochemical process units

Typical Monitoring Functions

• Radial vibration detection
• Axial displacement measurement
• Shaft position and movement tracking
• Speed and dynamic phase reference
• Early detection of imbalance, misalignment, or looseness
• Integration into predictive maintenance platforms
