Product Overview
Downtime from sensor failure costs industrial operations thousands per minute. The Bently Nevada 330172-00-40-10-02-00 delivers robust, reliable proximity sensing designed to minimize unexpected failures and extend service intervals. This 5mm probe with armor is part of the 3300 series, engineered for precision vibration monitoring in critical rotating machinery. Built in the USA, it features a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case for long-lasting performance in harsh environments.
Technical Specifications Breakdown
-
Power Requirement: Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Operation above -23.5 Vdc reduces linear range.
-
Sensitivity: Less than 2 mV change in output voltage per volt change in input voltage ensures stable readings.
-
Output Resistance: 50 W.
-
Probe DC Resistance: 7.59 ± 0.50 Ω for 1.0 m cable length.
-
Temperature Range: -35°C to +177°C (-31°F to +351°F). Exposing to below -34°C may damage the pressure seal.
-
Minimum Cable Bend Radius: 25.4 mm (1.0 in) prevents signal degradation.
-
Tensile Strength: 222 N (50 lbf) for probe case to lead and lead to extension cable connectors.
These parameters ensure the Bently Nevada 330172-00-40-10-02-00 provides accurate, repeatable measurements even under thermal and mechanical stress.
Applications
In power generation, oil and gas, and petrochemical plants, the Bently Nevada 330172-00-40-10-02-00 monitors shaft vibration on turbines, compressors, and pumps. Its 1/4-28 UNF thread and 4.0 in overall case length allow secure mounting in standard tapped holes. The armored construction protects against mechanical damage, reducing replacement frequency and lowering total cost of ownership—a direct return on investment.
Installation & Setup
Mount the probe using a #3 or larger tap drill for the 1/4-28 thread. Maximum thread engagement is 0.375 in. Recommended probe case torque is 5.1 N·m (45 in·lb); do not exceed 7.3 N·m (65 in·lb). Connector-to-connector torque maximum is 0.565 N·m (0.42 ft·lbf). Avoid installing in environments below -34°C to preserve the pressure seal. The miniature coaxial ClickLoc connector ensures secure cable attachment.
Maintenance & Reliability
The Bently Nevada 330172-00-40-10-02-00 operates reliably across a wide temperature schedule: for EPL Ga and Gc, temperature classifications range from T1 (-55°C to +232°C) down to T5 (-55°C to +40°C). For EPL Dc, classifications further refine limits. Inspect the probe cable for wear at the bend radius (minimum 25.4 mm). The gold-plated brass or beryllium copper connectors resist corrosion. Routine checks of thread engagement and torque prevent misalignment. With proper care, this probe delivers years of maintenance-free service, maximizing equipment uptime.
Selection Guide & Purchasing Advice
Before purchasing verify your system voltage and cable length requirements. This 330172-00-40-10-02-00 configuration includes a 1.0 m cable (total length option 1 0) and no agency approvals (0 0). For other lengths or approvals, order a different suffix. PLC Source PRO stocks genuine Bently Nevada 330172-00-40-10-02-00 probes and offers expert support to match your application.
