Product Overview

The Bently Nevada 9200-06-02-10-00 is a two-wire velocity seismoprobe transducer for higher frequency applications. This device measures absolute casing vibration on faster rotating machinery. It features a 10 Hz (600 cpm) minimum operating frequency. The 9200-06-02-10-00 uses a side mount terminal block without an integral cable. Engineers choose this version for machines running above 600 revolutions per minute.

The Bently Nevada 9200-06-02-10-00 has a 10 Hz minimum frequency. This differs from standard 4.5 Hz models like the 9200-01-05-10-00.

Higher Frequency Response Advantage

This 9200-06-02-10-00 model features a 10 Hz (600 cpm) minimum operating frequency. This design suits specific high-speed machinery.

• Gas turbines – running above 3000 rpm require higher frequency response

• Centrifugal compressors – typical speeds of 5000 to 15000 rpm

• High speed pumps – boiler feed pumps and multistage units

• Electric motors – two pole motors running at 3600 rpm

• Blowers and fans – direct drive units with high rotational speeds

The 10 Hz cutoff means the Bently Nevada transducer ignores very low frequency vibrations below 600 cpm. This prevents false readings from thermal growth or slow machine movements.

Side Mount Terminal Block Design

This 9200-06-02-10-00 uses a side-mounted terminal block instead of a top mount. This offers specific installation benefits.

• Lower profile height – fits in tight vertical clearances

• Easier wiring access – terminals face sideways for better tool access

• Cable strain relief – wires exit horizontally, reducing bending stress

• Protective cover included – snap-on cap seals the terminal area

• Standard screw terminals – accept 16 to 22 AWG shielded wire

The side mount design of the 9200-06-02-10-00 works well inside junction boxes or conduit hubs. Use shielded twisted-pair cable like Belden 8760 for best signal integrity.

Installation Guide

Follow these steps to install the 9200-06-02-10-00 correctly.

1. Check Machine Speed: Verify the machine runs above 600 rpm. The 10 Hz minimum frequency suits 10 Hz to 2 kHz operation.

2. Prepare Mounting Surface: Clean the bearing housing or casing area. Remove rust, paint, or old gasket material.

3. Install M10x1 Stud: Thread the stud into a prepared hole. Apply medium strength thread locker for security.

4. Mount the Transducer: Screw the Bently Nevada 9200-06-02-10-00 onto the stud. Hand tighten plus one quarter turn.

5. Access Side Terminal: Remove the side cover to expose terminal screws. Connect wires to terminals A and B.

6. Route Shielded Cable: Run cable away from variable frequency drives. Ground the shield only at the monitor end.

7. Close and Seal: Replace the side terminal cover. Ensure the gasket seals properly against moisture.

Do not exceed 15 Nm torque on the M10x1 stud. The 9200-06-02-10-00 requires the 0° ±100° orientation for specified sensitivity.

Common FAQs

1. What machines work best with the 9200-06-02-10-00?
This Bently Nevada transducer suits high speed machinery above 600 rpm. Gas turbines, centrifugal compressors, and two-pole motors are typical applications.

2. Why does this model have a 10 Hz minimum frequency instead of 4.5 Hz?
The 9200-06-02-10-00 rejects very low frequency vibrations below 10 Hz. This prevents interference from thermal expansion or structural movement on fast machines.

3. Can I use the side mount terminal in wet environments?
Yes, the side terminal cover provides IP66 protection when properly sealed. The 9200-06-02-10-00 resists dust and moisture with the cover installed.

4. How does the 0° ±100° mounting angle affect installation?
The wide ±100° tolerance means precise angular alignment is not critical. The 9200-06-02-10-00 maintains rated sensitivity across a broad orientation range.

5. What is the maximum frequency this 9200 model can measure?
The 9200-06-02-10-00 accurately measures vibration up to 2 kHz (120,000 cpm). Above this frequency, amplitude errors may exceed 10%.

Typical Applications

The Bently Nevada 9200-06-02-10-00 serves many high speed rotating machinery monitoring needs.
