Bently Nevada 9200-06-05-05-00 Two-Wire Velocity Seismoprobe Transducer

The Bently Nevada 9200-06-05-05-00 is a rugged two-wire velocity transducer. This device measures absolute casing vibration on rotating machinery. It suits turbines, compressors, pumps, and fans. The Bently Nevada 9200-06-05-05-00 delivers reliable data without external signal conditioning.

Key Technical Specifications

This transducer offers a sensitivity of 20 mV/mm/s (500 mV/in/s). The tolerance stays within ±5% when properly terminated. Calibration uses a 10 kΩ load between terminals A and B. Output is taken directly across pins A and B. The dynamic operating range reaches 2.54 mm (0.100 in) peak-to-peak maximum displacement.

Velocity range hits 25 mm/s (1 in/s) at +22°C. This measurement uses 100 Hz casing vibration with a 10 kΩ load. Coil resistance sits at 1.25 kΩ ±5%. Locked coil inductance is 125 mH typical. The sensitivity temperature coefficient is 0.2% per °C.

Mounting and Connector Options

The mounting angle option is 06 at 0° ±100°. Minimum operating frequency starts at 10 Hz (600 cpm). Connector option 05 provides a terminal block top mount. This terminal block allows direct screw-type wire connection. Mounting base option 05 uses no circular base. Instead it has a 1/2-20 UNF-3A stud. Agency approval option 00 means no approvals are required.

The 0° orientation provides wide angular tolerance of ±100°. The 1/2-20 UNF thread matches many standard mounting holes. This stud type is common in North American industrial machinery.

Environmental and Temperature Ratings

Operating and storage temperature ranges from -29°C to +121°C (-20°F to +250°F). The case uses anodized aluminum A204 for corrosion resistance. Gasket material is Neoprene for the 9200 series. The device resists dust and moisture effectively. Relative humidity tolerance reaches 95% noncondensing.

The transducer handles 100% humidity when ordered with an integral cable (non-submerged). This makes it suitable for humid industrial environments. Avoid direct water immersion without proper cable protection.

Mechanical Dimensions and Weight

Typical height measures 102 mm (4 inches). This depends on the selected connector option. Diameter is 41 mm (1.6 inches) typical. Weight of this configuration is 300 grams (10.5 ounces) typical. The absence of a circular base slightly reduces overall weight.

The Bently Nevada 9200-06-05-05-00 has a lower profile than base-mounted versions. The 1/2-20 UNF stud screws directly into prepared holes. This design suits machinery with pre-threaded mounting ports.

Installation Guide

Follow these steps for proper installation:

1. Clean the threaded mounting hole on the machinery casing.

2. Apply anti-seize compound to the 1/2-20 UNF stud threads.

3. Screw the transducer into the hole by hand until snug.

4. Tighten with a wrench no more than one additional turn.

5. Strip wire ends and insert them into the terminal block.

6. Connect wires to terminal A and terminal B firmly.

7. Terminate the output with a 10 kΩ load resistor.

8. Secure wires away from moving parts and heat sources.

Do not overtighten the 1/2-20 UNF stud into the mounting hole. Keep the terminal block screws snug but not stripped. Avoid exceeding +121°C casing temperature.

Common FAQs (3-5 questions)

Q1: What is the difference between base option 05 and 10?
Option 05 has no circular base and uses a 1/2-20 UNF stud. Option 10 has a circular base with an M10x1 stud. Choose based on your mounting hole thread.

Q2: What wire size fits the terminal block?
The terminal block accepts 16 to 22 AWG stranded or solid wire. Use copper wire only for reliable connections.

Q3: Can I use this transducer below 10 Hz vibration?
The output will drop significantly below 10 Hz. The Bently Nevada 9200-06-05-05-00 is designed for machinery above 600 cpm only.

Q4: How do I check if the transducer is damaged?
Measure coil resistance between terminal A and terminal B. A healthy unit shows 1.25 kΩ ±5%. Any open or short circuit means damage.

Q5: Is the 1/2-20 UNF thread compatible with metric holes?
No, 1/2-20 UNF is an imperial thread. Do not force it into metric M10 or M12 holes. Use the correct adapter if needed.

Summary for Buyers

The Bently Nevada 9200-06-05-05-00 two-wire velocity transducer delivers accurate casing vibration data. Its 20 mV/mm/s sensitivity and 10 Hz low frequency suit higher speed machinery above 600 cpm. The 1/2-20 UNF stud matches North American standard mounting ports. Order this new original unit for reliable condition monitoring on your critical assets.
