Description：

The 3300 XL 25 mm Transducer System consists of a separate25 mm probe, an extension cable, and a 3300 XL 25 mmProximitor Sensor. The 0.787 V/mm (20 mV/mil) output givesthis system a linear range of 12.7 mm (500 mils). Based on thislinear range, the 3300 XL 25 mm Transducer System is suitablefor measuring differential expansion (DE) on mid-size to largesteam turbine generators caused by the difference in growthrates between the turbine rotor and the machine stator (casing).

Frequently asked questions

Q1: What is the Bently Nevada 330851-04-000-030-10-00-05 used for?

A1:The Bently Nevada 330851-04-000-030-10-00-05 is a 3300 XL 25 mm proximity probe designed for non-contact measurement of shaft position, vibration, and displacement in critical rotating machinery such as turbines, compressors, motors, and generators.

Q2: What power supply does this 330851-04-000-030-10-00-05 proximity probe require?

A2:The 330851-04-000-030-10-00-05 probe system requires a DC power supply of -17.5 VDC to -26 VDC to operate correctly with the associated proximity transducer system.

Q3: What is the linear measurement range of the 330851-04-000-030-10-00-05 probe?

A3:The 330851-04-000-030-10-00-05 probe provides a linear measurement range of 12.7 mm (500 mils), enabling accurate monitoring of shaft movement over a wide displacement range.

Q4: What does the overall case length option 030 indicate?

A4:The 030 option specifies an overall case length of 30 mm, allowing the probe to fit installations with specific mounting and space requirements.

Product Applications

Thermal power plants, nuclear power plants, and hydroelectric power stations: Monitoring the axial displacement and rotor vibration of large steam turbines, gas turbines, and generator main shafts to prevent catastrophic damage such as blade rubbing against windows.

Oil refineries and natural gas pressurization stations: Continuous condition monitoring (CMS) for hydrogen feed pumps, large centrifugal compressors, and reciprocating compressors.

Large chemical plants and ethylene plants: Monitoring the condition of core bearings in high-risk, high-speed cracked gas compressors and blowers.

Steel manufacturing plants (metallurgical industry): Early warning of abnormalities in heavy-duty, high-vibration equipment such as blast furnace blowers and large rolling mill drive systems.

Large water conservancy pumping stations and ore dressing plants: Monitoring the wear condition of bearings in high-power irrigation and drainage pumps and ore crushers.
