Bently Nevada 26530-12-10-03-018-085-24-03-00 Dual Probe Transducer System

Product Description:

The 26530 Dual Probe Transducer System consists of a proximity probe and a seismic or Velomitor transducer installed at approximately the same point in a common transducer housing. This transducer system is capable of making four separate measurements: shaft relative radial position (displacement) relative to the probe mounting location, measured by the proximity probe; shaft relative radial dynamic motion (vibration) relative to the probe mounting location, measured by the proximity probe; machine casing absolute vibration measured by the seismic vibration; and shaft absolute motion represented by the summation of the seismic signal (after integration to displacement) and the shaft relative. The system provides the best measurement data when the transducer housing is mounted on a portion of the bearing housing or cover that is mechanically referenced to the bearing. For complete machinery monitoring diagnostics using orbit analysis and shaft centerline position information, two Dual Probe assemblies in an X-Y configuration are required per radial bearing. A probe support/oil sleeve is available as an option to protect the transducer system from oil and provide additional support for the probe.

Frequently Asked Questions (FAQ):

What is the 26530-12-10-03-018-085-24-03-00？
The Bently Nevada 26530-12-10-03-018-085-24-03-00 is a highly specific Dual Probe Transducer System used to simultaneously monitor shaft displacement and absolute casing/bearing housing vibration on heavy rotating machinery.

Where is this transducer assembly typically installed?
It is mounted directly onto fluid-film bearing housings or covers of critical turbomachinery, such as steam turbines, centrifugal compressors, and large pumps. To achieve complete machine diagnostics using orbit analysis and shaft centerline tracking, you must install two Dual Probe assemblies in an  X-Y orthogonal configuration on each radial bearing.

What are the setup and calibration targets for the proximity probe?

The 3300 XL 8 mm proximity probe features a linear range of 80 mils (2.0 mm) with a standard scale factor sensitivity of 200 mV/mil. During installation, mechanical gapping should target a nominal gap voltage of -10 VDC (typically within a linear range of -8 VDC to -12 VDC) against a standard AISI 4140 steel target.
