Description
The 3300/65 Dual Probe Monitor combines the shaft relative displacement signal of a Bently Nevada proximity transducer and casing vibration from a velocity transducer, both of which are installed in the same axis on the machine, into one measurement of shaft absolute vibration. Dual Probe Monitors are designed for machines with fluid film bearings, such as large steam and gas turbines, where a significant amount of shaft vibration is transmitted to the case. If you are uncertain as to whether your machine transmits significant vibration to the casing, we can provide engineering services to determine the characteristics of your machine and recommend an appropriate monitoring system. Four distinct measurements are provided by the Dual Probe Monitor: • Shaft relative vibration - A proximity probe measurement of shaft vibration relative to the bearing housing. • Bearing housing vibration - A seismic measurement of the bearing housing vibration relative to free space. • Shaft absolute vibration - A vector summation of shaft relative vibration and bearing housing vibration. • Shaft average radial position relative to the bearing clearance - A proximity probe dc gap measurement.
