Description：

When combined with a 3300 XL Proximitor Sensor and XLextension cable, the system provides an output voltage thatis directly proportional to the distance between the probe tipand the observed conductive surface. The system canmeasure both static (position) and dynamic (vibration) data.Its primary use is in vibration and position measurementapplications on fluid-film bearing machines, as well asKeyphasor measurement and speed measurementapplications6.

The system provides an accurate, stable signal output over awide temperature range. All 3300 XL Proximity TransducerSystems achieve this level of performance with completeinterchangeability of probe, extension cable, and Proximitorsensor, eliminating the need for individual componentmatchingor bench calibration.

Frequently asked questions

1. What is the Bently Nevada 330174-00-08-50-02-05 used for?

The Bently Nevada 330174-00-08-50-02-05 is a 3300 series 5 mm proximity probe designed for non-contact vibration and shaft position monitoring in rotating machinery such as turbines, motors, compressors, and pumps.

2. What does the “5 mm Proximity Probe” mean?

The 5 mm designation refers to the probe tip diameter. This compact probe size is suitable for installations with limited mounting space while still providing accurate shaft displacement measurements.

3. What does the Unthreaded Length Option “00” indicate?

Option “00” means the probe has an unthreaded length of 0 mm, so the probe body is fully threaded for secure mounting flexibility.

4. What does the 330174-00-08-50-02-05 Overall Case Length Option “08” mean?

Option “08” indicates the probe case length is 80 mm.

5. What is the 330174-00-08-50-02-05 total cable length of this model?

The “50” option specifies a total system length of 5.0 metres (16.4 feet).

Product Applications

Power Industry: Used in steam turbines, gas turbines, generators, water turbines, and large feedwater pumps in thermal power plants, nuclear power plants, and hydropower plants. Used to monitor radial vibration and eccentricity of shafts to prevent blade rubbing against cylinders.

Oil and Gas: Used in high-power centrifugal compressors and pipeline pumps in long-distance oil/gas pipeline booster stations and LNG receiving terminals. Used for fault early warning of equipment operating continuously for long periods.

Petrochemical and Chemical Industries: Used in large cracking gas compressors, hydrogenation feed pumps, and fans in ethylene plants and synthetic ammonia plants. Used to monitor mechanical deformation and bearing condition in flammable and explosive environments.

Metallurgy and Iron & Steel: Used in blast furnace blowers, blast furnace gas residual pressure power generation (TRT) units, and large exhaust fans. Used to ensure the safety of core rotating equipment during continuous smelting processes.
