Bently Nevada 3300 XL 25 mm Proximity Transducer System-深圳市大成机电技术有限公司手机版

详细介绍

Description
The 3300 XL 25 mm Transducer System consists of a separate 25 mm probe, an
extension cable, and a 3300 XL 25 mm Proximitor Sensor. The 0.787 V/mm (20
mV/mil) output gives this system a linear range of 12.7 mm (500 mils). Based on
this linear range, the 3300 XL 25 mm Transducer System is suitable for
measuring differential expansion (DE) on mid-size to large steam turbine
generators caused by the difference in growth rates between the turbine rotor
and the machine stator (casing).
Measuring Differential Expansion(DE)
The Differential Expansion measurement is made by two proximity transducers
observing a collar or ramp some distance from the thrust bearing. Typical
transducer mounting arrangements are:
• Two transducers observing the same side of a collar.
• Two complementary input transducers observing opposite sides of a

collar, effectively doubling the measurable DE range.

0 5 Multiple Approvals
Note: For a shorter delivery time, order
commonly stocked multi-approvals
probes. Currently, stocked probes consist
of the following part numbers:
