The Bently Nevada 9200-03-01-10-00 uses a 90 degree calibrated orientation. This differs from standard 0 degree models like the 9200-01-05-10-00.

90 Degree Mounting Angle Advantage

This 9200-03-01-10-00 model features a 90° ±2.5° mounting angle. This design serves specific installation needs.

• Vertical shaft machines – measure horizontal casing vibration correctly

• Tight clearance areas – mount on side walls or bulkheads

• Horizontal bearing housings – place transducer on top or bottom surface

• Standardized orientation – matches many OEM machine specifications

• Simplified retrofits – replaces older 90 degree sensors directly

The 90 degree angle means the transducer’s sensitive axis runs perpendicular to the mounting surface. Install this Bently Nevada unit on a horizontal surface to measure vertical vibration. Install it on a vertical surface to measure horizontal vibration.

Terminal Block Design Features

This 9200-03-01-10-00 uses a top-mounted terminal block instead of an integral cable. This offers several practical benefits.

• No fixed cable length – choose exactly what your installation needs

• Easy field termination – standard screw terminals accept 16-22 AWG wire

• Lower replacement cost – keep existing field wiring when changing sensors

• Simplified conduit connections – wire directly into junction boxes

• Faster troubleshooting – access terminals without removing the transducer

Use shielded twisted-pair cable for the 9200-03-01-10-00. Belden 8760 or 8770 works well for runs up to 305 meters. Connect the shield only at the monitor end to avoid ground loops.

Installation Guide

Follow these steps to install the 9200-03-01-10-00 correctly.

1. Identify Vibration Direction: Determine which machine axis needs measurement. The 90 degree sensor measures perpendicular to its mounting surface.

2. Prepare Mounting Point: Clean the machine surface thoroughly. Remove old gasket material and debris.

3. Install M10x1 Stud: Screw the stud into a threaded hole on the machine. Apply medium strength thread locker.

4. Mount the Transducer: Screw the Bently Nevada 9200-03-01-10-00 onto the stud. Hand tighten plus one quarter turn only.

5. Wire Terminal Block: Connect two wires to terminals A and B. Use a 10 kΩ load resistor at the receiving device.

6. Route and Secure Cable: Run shielded cable away from power cables. Use cable ties every 30 cm for support.

7. Verify Installation: Measure coil resistance across terminals A and B. A good unit reads 1.25 kΩ ±5%.

Do not exceed 15 Nm torque on the mounting stud. The 9200-03-01-10-00 requires the 90° ±2.5° orientation for rated sensitivity.

Common FAQs

1. When should I use the 9200-03-01-10-00 instead of the 0 degree version?
Use this Bently Nevada model when machine access requires a 90 degree mounting angle. Typical applications include vertical pumps and turbine side covers where horizontal mounting is impossible.

2. Does the 90 degree angle affect sensitivity compared to a 0 degree sensor?
No, the 9200-03-01-10-00 provides the same 20 mV/mm/s sensitivity. The internal coil assembly is simply rotated 90 degrees during factory calibration.

3. What is the maximum cable length for this 9200 model?
Keep cable length under 305 meters (1000 feet) for the 9200-03-01-10-00. Longer runs increase resistance and reduce signal amplitude.

4. Can I use this CEV58M transducer in a vertical down position?
Yes, the 9200-03-01-10-00 works in any orientation. The internal spring-mass system handles vertical, horizontal, or inverted mounting without performance loss.

5. How do I convert the velocity output to acceleration?
Multiply the 9200-03-01-10-00 output by 2πf, where f is frequency in Hz. For example, at 100 Hz, multiply by 628 to get mm/s².

Typical Applications

The Bently Nevada 9200-03-01-10-00 serves many rotating machinery monitoring needs with its 90 degree angle.

• Vertical turbine pumps – measure horizontal casing vibration on round housings

• Paper machine rolls – mount on bearing housings with limited top access

• Cooling tower fan drives – install on gearbox side surfaces

• Centrifugal compressors – replace older 90 degree sensors without rewiring

• Wind turbine gearboxes – mount on inclined surfaces at standard orientation

• Marine propulsion shafts – install on bulkheads with perpendicular measurement

This transducer connects to Bently Nevada 1900/65 monitors or 3500 series racks. It also works with any device accepting a 20 mV/mm/s velocity input.

Compliance and Quality
