330730-080-12-05 | Bently Nevada | 3300 XL 11 mm Extension Cable

A. Technical Overview

The 330730-080-12-05 extends the 3300 XL 11 mm proximity probe signal path between a Bently Nevada 3300 XL eddy-current transducer and its matching 3300 XL Monitor (e.g., 3500/22, 3500/25) in a 3500 System rack. It processes analog voltage signals (−24 VDC to +24 VDC range) without amplification or conditioning—preserving millivolt-per-mil linearity and phase fidelity. The cable integrates into the 3500 System’s isolated backplane architecture: shielded twisted-pair construction and grounded braided shielding protect against EMI-induced common-mode noise on rotating machinery installations. It does not terminate or convert protocols; it maintains native 3300 XL analog output integrity across distances up to 80 ft (24.4 m). Compatible with 3500 System racks operating under IEEE 1159 Class A power quality conditions and integrated into Experion PKS via 3500 System I/O modules.

C. Operational Capabilities

In Oil & Gas, this cable routes vibration signals from compressor train probes in API 670-compliant monitoring systems—maintaining G3 conformal coating compatibility on terminations for offshore humidity exposure. In Power Generation, it supports turbine-generator differential expansion monitoring at 250 °F ambient cabinet temperatures (with optional heat-shrink overmold). Aerospace test stands use it for high-speed shaft runout validation where sub-microsecond response time ensures accurate orbit reconstruction. Supports hot-swap of 3500 monitors without signal interruption. No SIL rating applies—this is a passive analog extension component, not a safety instrumented function device. Meets IEC 61000-4-3 (10 V/m radiated immunity) and IEC 61000-4-6 (10 V conducted immunity) when installed per 3300 XL grounding guidelines.

D. Technical FAQ

Q1: Does the 330730-080-12-05 support 3300 XL 2.0 firmware monitors (e.g., 3500/22M v2.0)?

A: Yes. This cable is protocol-agnostic and electrically identical across all 3300 XL monitor generations (v1.0 through v2.5). It carries unconditioned analog voltage only—no digital handshake or firmware negotiation occurs. Verify mechanical compatibility: 3300 XL 2.0 monitors retain the same 4-pin M12 connector pinout (Signal, Return, Shield, +24 VDC sense).

Q2: Can this cable be spliced or re-terminated in the field to adapt to non-standard probe lengths?

A: No. Splicing degrades impedance continuity and introduces reflection points that distort high-frequency components (>5 kHz). Bently Nevada specifies zero-field termination. Use only factory-assembled cables with crimped, molded M12 connectors meeting IP67 sealing. Field re-termination voids conformance to API RP 670 Section 5.4.2 (signal integrity verification requirements).
