Application Scenarios

Steam & Gas Turbine Monitoring: Connect proximity probes measuring shaft vibration, axial position, and differential expansion on turbine-generator sets. The 33-foot length accommodates routing from bearing housings to control room monitoring racks while the armor protects against thermal cycling and mechanical stress in high-temperature turbine environments. Delivers the signal fidelity required for early detection of rub conditions, bearing degradation, and rotor instability.

Centrifugal Compressor Protection: Link radial vibration sensors and thrust position transducers to 3500 monitoring systems on critical compressor trains. Electromagnetic shielding eliminates interference from motor drives and electrical panels, while armor construction survives the vibration and movement typical of compressor skid installations. Supports surge detection, bearing monitoring, and trip protection functions.

Large Motor & Generator Instrumentation: Instrument electric motors and generators with shaft vibration and eccentricity monitoring. The cable's high-temperature rating handles installations near motor windings and bearings, while dual shielding rejects electrical noise from motor switching and harmonic currents. Enables predictive maintenance programs that reduce unplanned downtime by 40-70%.

Pump Vibration Analysis: Deploy on critical process pumps, boiler feed pumps, and cooling water systems requiring continuous vibration surveillance. The 33-foot length provides flexibility for installations with remote sensor locations, while sealed construction resists moisture, chemical vapors, and washdown environments common in pump applications.

Hazardous Area Installations: When combined with certified intrinsic safety barriers, supports Division 1 and Zone 1 classified locations in refineries, chemical plants, and offshore platforms. Armored construction meets mechanical protection requirements while maintaining intrinsic safety circuit integrity.

Technical Parameters & Selection Guide

Selection Criteria: Choose the 16710-33 when your installation requires cable runs between 25-35 feet with maximum signal integrity. For shorter runs, consider the 16710-30 (30ft) or 16710-32 (32ft) variants. For runs exceeding 35 feet up to the recommended 100-foot maximum, select longer cable assemblies or implement proximitor extension cables. Always verify that total system capacitance remains within transducer system specifications (typically 9,000 pF maximum for 3300 XL systems). In applications with extreme mechanical stress or rodent exposure, armored cables like the 16710-33 provide superior protection compared to standard jacketed interconnects.

Extended Functions

IoT Integration Capability: When connected to Bently Nevada System 1 software platforms or third-party SCADA systems via 3500 rack Ethernet modules, the 16710-33 enables remote vibration monitoring, cloud-based analytics, and predictive maintenance algorithms. Signal data transmitted through this cable can feed machine learning models for anomaly detection and remaining useful life calculations.

Frequently Asked Questions

What is the maximum cable length recommended for proximity sensor interconnect applications?
Bently Nevada engineering guidelines specify a maximum total interconnect cable length of 100 feet (30.5 meters) for 3300 XL and 3500 series proximity systems. The 33-foot 16710-33 provides excellent signal integrity while allowing additional extension cable if needed. Total system capacitance must remain below 9,000 pF to maintain transducer system linearity and frequency response.

Can this armored cable be installed in Class I Division 1 hazardous locations?
Yes, when properly installed with certified intrinsic safety barriers (such as Bently Nevada 93696 or 93697 series) and following API RP 505/IEC 60079 installation practices, the 16710-33 supports Division 1 and Zone 1 classified area installations. The armored construction provides the mechanical protection required in many hazardous area specifications.

How does the armored construction affect cable flexibility and installation?
The flexible stainless steel armor maintains a minimum bend radius of approximately 6 inches (150mm), allowing routing through cable trays, conduit systems, and around obstacles while protecting the internal conductors. The armor adds minimal weight (approximately 2.5 kg for 33-foot length) and can be easily cut and terminated with standard cable preparation tools.

Is the 16710-33 compatible with non-Bently Nevada monitoring systems?
While optimized for Bently Nevada platforms, the 16710-33 can be used with any proximity sensor system requiring low-capacitance shielded interconnect cables. Verify that your monitoring system's input impedance, voltage supply, and capacitance specifications are compatible. The cable's electrical characteristics support most eddy current proximity transducer systems from major manufacturers.

What connector termination options are available for the 16710-33?
Standard configurations include BNC connectors for rack-mount monitoring systems, MIL-C-5015 circular connectors for field junction boxes, or bare wire termination for custom installations. Specify your connector requirements at time of order. Field-installable connectors are also available for maintenance and repair applications.

How do I verify cable integrity after installation or during troubleshooting?
Use a precision capacitance meter to measure total cable capacitance (should match factory calibration certificate ±5%). Check shield continuity with a multimeter (should read <1 ohm end-to-end). Insulation resistance testing should exceed 1,000 megohms at 500VDC. Bently Nevada TK-3 test kits provide comprehensive cable and transducer system verification capabilities.
