Product Overview
The Bently Nevada 330174-00-03-10-02-CN is a 3300 5mm probe with M8 x 1 thread and integral armor, built for continuous vibration monitoring in rotating machinery. Manufactured in the U.S.A., this industrial automation module uses a polyphenylene sulfide (PPS) probe tip and an AISI 304 stainless steel case to resist process contaminants and mechanical wear. With a 1.0 metre total length and a miniature coaxial ClickLoc connector, the 330174-00-03-10-02-CN delivers stable proximity measurements in tight installations.
Technical Specifications
The 330174-00-03-10-02-CN is specified for proximity transducer systems operating between +18°C and +27°C with a -24 Vdc supply, a 10 kW load, an AISI 4140 steel target, and a probe gapped at 1.27 mm. Key parameters include:
- 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
- Probe DC resistance: 7.59 ± 0.50 Ω for the 1.0 metre version
- Probe cable: 75 Ω triaxial, FEP insulated; available in 0.5, 1, 2, 5, or 9 metre lengths
- Probe case torque: 5.1 N·m recommended; 7.3 N·m maximum
- Probe temperature range: -35°C to +177°C

Installation & Mounting Guidance
Proper mounting prevents the most common probe failures. Thread engagement for the M8 x 1 case must not exceed 12 mm. Tighten the probe case to 5.1 N·m, and never exceed 7.3 N·m. Keep the cable bend radius above 25.4 mm to avoid stressing the FEP insulation. Connector-to-connector torque should stay below 0.565 N·m. The Bently Nevada 330174-00-03-10-02-CN armored design helps protect the cable in routing areas where abrasion or impact is likely.
Maintenance & Reliability
The 330174-00-03-10-02-CN withstands -35°C to +177°C probe temperatures, but exposing the probe below -34°C may cause premature pressure seal failure. The armor reduces mechanical damage, while the 222 N tensile strength at the probe lead and connectors keeps the assembly intact during normal service. Magnetic field testing at 60 Hz and up to 300 Gauss shows minimal output voltage effects—at a 50 mil gap the probe contributes only 0.0014 mil pp/gauss—so this model remains stable near electric machinery.
Applications & Selection Guide
This Bently Nevada 330174-00-03-10-02-CN suits turbomachinery, pumps, compressors, and motors where shaft vibration must be measured accurately. The armored cable and stainless steel body make it a strong choice for high-traffic or dirty environments. Before ordering, verify your required total length, connector style, and agency approval code. The option code 02 indicates a miniature coaxial ClickLoc connector, and CN indicates a country-specific approval. PLC Source PRO can help you confirm fit for your monitoring system.
