Bently Nevada 330174-00-02-10-02-CN Key Features & Applications

Product Overview

Part of the Bently Nevada 3300 family, the 330174-00-02-10-02-CN is a 3300 5mm probe with an M8 x 1 threaded case and armor. This Industrial Automation Module is manufactured in the U.S.A. for reliable non-contact shaft vibration and position monitoring. The armored construction reduces the risk of cable damage and connector strain, two common failure points in proximity measurement systems.

Technical Specifications

Unless otherwise noted, the following specifications apply to a proximity transducer system operating between +18°C and +27°C with a -24 Vdc power supply, a 10 kW load, an AISI 4140 steel target, and a probe gapped at 1.27 mm.

Key electrical and mechanical parameters:

• Power supply: -17.5 Vdc to -26 Vdc at 12 mA maximum consumption
• Supply sensitivity: less than 2 mV change in output voltage per volt change in input voltage
• Output resistance: 50 W
• Probe DC resistance (1.0 m length): 7.59 ± 0.50 Ω from center conductor to outer conductor
• Probe tip material: polyphenylene sulfide (PPS)
• Probe case material: AISI 303 or 304 stainless steel; this option uses AISI 304
• Probe cable: 75 Ω triaxial, FEP insulated, available in 0.5, 1, 2, 5, or 9 meter lengths
• Tensile strength: 222 N (50 lbf) probe case to probe lead; 222 N probe lead to extension cable connectors
• Probe case torque: 5.1 N·m recommended, 7.3 N·m maximum
• Connector-to-connector torque: 0.565 N·m maximum
• Minimum cable bend radius: 25.4 mm (1.0 in)
• Probe temperature range: -35°C to +177°C
• Thread engagement: maximum 12 mm for M8 x 1 thread

Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range.

Industry Applications

The 330174-00-02-10-02-CN delivers accurate displacement measurements in high-vibration environments. Typical applications include bearing vibration monitoring, shaft radial position measurement, and rotating machinery protection on industrial equipment.

Because the probe is armored and fitted with a miniature coaxial ClickLoc connector, it is well suited for installations where cables must endure repeated flexing or mechanical stress. This directly addresses the common failure mode of intermittent signals caused by damaged probe leads or loose connectors.

Installation & Setup Guidance

When installing the 330174-00-02-10-02-CN, follow the torque limits provided in the specification. Apply 5.1 N·m of torque to the probe case for normal installations and do not exceed 7.3 N·m. Keep the cable bend radius at or above 25.4 mm to protect the triaxial cable.

For the M8 x 1 thread, maximum thread engagement is 12 mm. Adjust the probe gap carefully; the standard calibration gap of 1.27 mm applies for the specified measurement conditions. After mounting, verify the connector is seated securely to avoid connector-to-connector torque beyond 0.565 N·m.

Maintenance & Reliability

Routine inspection of the probe cable and connector is essential for long service life. Exposing the probe to temperatures below -34°C may cause premature failure of the pressure seal, so confirm ambient conditions stay within the rated range of -35°C to +177°C.

Check the torque of the probe and connector periodically. Re-tightening to the recommended values helps prevent vibration-induced loosening, a common cause of measurement drift. The steel armor and PPS tip provide durable protection, but regular visual checks remain the simplest way to avoid unexpected downtime.

Selection Guide & Purchasing Advice

Before purchasing a replacement, verify the exact model number 330174-00-02-10-02-CN against your existing system requirements. Confirm the unthreaded length, overall case length, total length, connector style, and agency approval option match the probe you are replacing.
