Technical Specifications

Sensitivity and Calibration:

• The Bently Nevada 9200-03-01-01-00 offers 20 mV/mm/s (500 mV/in/s) sensitivity.

• Accuracy is ±5% when properly terminated.

• The unit must be oriented at the correct calibration angle.

• Calibration load uses a 10 kΩ resistor between Terminal A and B.

• Output is taken across pins A and B.

• Temperature coefficient is 0.2% per °C.

Dynamic Operating Range:

• Maximum displacement is 2.54 mm (0.100 in) peak to peak.

• Velocity range reaches 25 mm/s (1 in/s) at +22 °C.

• This rating applies to casing vibration at 100 Hz.

• The test uses a 10 kΩ load for measurement.

Electrical Characteristics:

• Coil resistance is 1.25 kΩ ±5%.

• Locked coil inductance is 125 mH (typical value).

Environmental Specifications

The Bently Nevada 9200-03-01-01-00 operates from -29°C to +121°C. Storage temperature matches the same range of -29°C to +121°C. For high-temperature versions, the 74712 option reaches +204°C. The transducer resists dust and moisture effectively. Relative humidity tolerance goes up to 95% (non-condensing). The unit handles 100% humidity when non-submerged. This requires an integral cable option for full protection.

Physical Construction:

• Case and adapter material is anodized aluminum A204.

• Gasket material is neoprene for reliable sealing.

• Height measures 102 mm (4 inches) typical.

• This height varies depending on the connector option selected.

• Diameter is 41 mm (1.6 inches) typical.

Weight:

• The Bently Nevada 9200-03-01-01-00 weighs 300 grams (10.5 ounces) typical.

Installation Guide

Follow these steps to install the Bently Nevada 9200-03-01-01-00 correctly:

1. Prepare a flat mounting surface on your machine casing.

2. Drill and tap a hole for the 1/4-20 UNC stud.

3. Screw the circular mounting base onto the stud securely.

4. Mount the transducer at a 90° ±2.5° angle.

Frequently Asked Questions (FAQ)

1. Does the Bently Nevada 9200-03-01-01-00 need external power?
No, this is a passive two-wire velocity transducer. It generates its own output signal without external power.

2. What is the minimum frequency this transducer can measure?
The Bently Nevada 9200-03-01-01-00 has a minimum operating frequency of 4.5 Hz (270 cpm) at the 90° mounting angle.

3. Can I use this sensor above 121°C operating temperature?
The standard 9200 model works up to 121°C. For higher temperatures up to 204°C, order the 74712 high-temperature version.

4. What termination load should I use for this transducer?
You need a 10 kΩ load connected across output pins A and B. This load ensures proper sensitivity calibration of ±5%.

5. How do I interpret the full part number 9200-03-01-01-00?
The number breaks down as: 9200 series, option 03 for 90°/4.5Hz, option 01 for top connector, option 01 for circular base, and option 00 for no agency approvals.
