Product Introduction
When cable pull-out or probe tip separation threatens critical machinery monitoring, the Bently Nevada 330191-00-70-10-CN delivers exceptional reliability. This 3300 XL 8 mm ETR proximity probe incorporates patented TipLoc and CableLoc technologies to ensure a robust bond and high pull strength of 330 N (75 lbf). Designed for permanent installation in harsh environments, it prevents common failures like cable breakage and liquid ingress with the optional FluidLoc cable.
Technical Specifications Breakdown
The Bently Nevada 330191-00-70-10-CN operates on a supply voltage of -17.5 Vdc to -26 Vdc (nonincendive circuit) or -23 Vdc to -26 Vdc with barriers, with a maximum consumption of 12 mA. Its supply sensitivity is less than 2 mV/V, ensuring stable output. The output resistance is 50 Ω, and the nominal probe DC resistance (RPROBE) at 1.0 meter is 7.59 ± 0.50 Ω. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel. The connector uses gold-plated brass or beryllium copper, with maximum connector torque of 0.565 N·m (5 in·lbf). Temperature classification covers T1 to T5 for EPL Ga/Gc and specific ratings for EPL Dc.

Industry Applications
The Bently Nevada 330191-00-70-10-CN is ideal for vibration monitoring in rotating machinery such as turbines, compressors, pumps, and generators. Its robust design withstands physical abuse and oil exposure, making it suitable for petrochemical, power generation, and heavy industrial environments. The 8 mm probe diameter provides thicker encapsulation for enhanced durability.
Installation & Setup Guidance
When installing the Bently Nevada 330191-00-70-10-CN, ensure proper thread engagement: the 3/8-24 UNF thread has a maximum length of 0.563 inch. Use the specified torque of 0.565 N·m for connectors. The probe seals differential pressure via a Viton O-ring; note that probes are not pressure-tested before shipment. For one-meter system versions, no extension cable is required. The standard cable is 75 Ω triaxial with FEP or PFA insulation; optional armor (flexible SST) is available. Ensure the ambient temperature does not exceed the classification limits (e.g., T3: -55 °C to +120 °C).
Troubleshooting & Common Issues
Common issues with proximity probes include cable breakage and liquid ingress. The Bently Nevada 330191-00-70-10-CN addresses these with patented CableLoc (330 N pull strength) and optional FluidLoc cable to prevent oil leakage. If reduced linear range occurs, verify that supply voltage is more negative than -23.5 Vdc. For entity parameter compliance, use only BN extension cables connected to BN proximity systems.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 330191-00-70-10-CN, confirm the thread option (3/8-24 UNF), unthreaded length (0.0 in), overall case length (7 in), total length (1.0 meter), and agency approval (CN). This model is new and original in factory packing with a 12-month warranty. For reliable sourcing, PLC Source PRO supplies genuine Bently Nevada modules with fast shipping. Verify compatibility with your existing monitoring system before purchasing.
