Core Features & Technical Advantages

✓ Flexible Stainless Steel Armored Cable Protection
Ruggedized cable construction withstands crush forces to 1250N, resisting damage from falling objects, equipment impacts, rodent activity, and abrasive contact. The armor jacket surrounds PTFE-insulated conductors while maintaining flexibility for routing through tight spaces—critical for retrofits and confined machinery installations.

✓ Reverse Mount Configuration for Space-Constrained Applications
Cable exit positioned opposite to standard sensors enables installation in bearing housings, gearbox casings, and structural locations where forward-mount designs cannot physically fit. This orientation also provides superior vibration isolation by decoupling cable movement from machinery vibration through the self-locking Lemo connector.

✓ Extended 8-Meter Cable Length for Remote Converter Placement
Factory-terminated 8m cable eliminates field splicing while allowing CON021 converter mounting in protected control cabinets away from high-temperature zones, electromagnetic interference sources, and harsh environmental exposure. Reduces installation time and eliminates potential failure points from field connections.

→ Wide Bandwidth Dynamic Response (DC to 20 kHz)
CON021 converter captures both slow thermal growth during equipment startup and high-frequency vibration signatures including gear mesh frequencies, blade passing events, and bearing defect patterns. 15-microsecond rise time ensures faithful reproduction of transient mechanical events critical for fault diagnosis.

→ Universal Monitoring System Compatibility
Negative voltage output (-4V to -20V) interfaces directly with Bently Nevada 3300/3500 systems, Emerson AMS platforms, and generic PLC/DCS analog inputs without signal conditioning. Supports seamless integration into existing vibration monitoring architectures and plant-wide standardization initiatives.

→ IP66 Environmental Protection with Extended Temperature Range
Sensor head sealed against dust ingress and high-pressure water jets operates reliably from -35°C to +180°C. PEEK sensor tip and 316 stainless steel housing resist chemical attack from acids, alkalis, hydraulic fluids, and industrial solvents common in process environments.

Industrial Application Scenarios

Steel Mill Rolling Equipment Monitoring

Value: Reliable shaft position monitoring enables automated machinery protection trips, preventing catastrophic failures that could result in platform shutdown, environmental incidents, and multi-million dollar repair costs.

Cement Kiln Drive System Surveillance

Challenge: Rotary kiln main drive bearings and girth gear assemblies operate in dusty environments with temperatures to 180°C near kiln shells. Falling clinker and maintenance equipment damage standard sensors.

Solution: PEEK sensor tip withstands elevated temperatures while armored cable protection prevents damage from falling material and mechanical interference. Reverse mount fits within existing bearing housing geometry.

Value: Continuous monitoring of bearing clearances and gear runout detects misalignment and wear progression, enabling condition-based maintenance that extends component life by 30-50% compared to time-based replacement schedules.

Power Generation Turbine Monitoring

Challenge: Steam and gas turbines require precise shaft displacement measurement for thrust bearing monitoring and rotor position control, with sensors exposed to vibration, temperature cycling, and electromagnetic interference from generators.

Solution: High-bandwidth CON021 converter captures transient events during startup/shutdown while armored cable routing away from high-voltage conductors minimizes EMI. Reverse mount accommodates tight clearances in turbine pedestals.

Value: Accurate thrust position monitoring prevents rotor contact with stationary components, avoiding blade damage and catastrophic failures that require months-long outages for turbine rebuilds.

Frequently Asked Questions

What advantages does armored cable construction provide over standard cable variants?

Armored cable extends sensor system life by 3-5x in environments with mechanical hazards including falling objects, equipment impacts, abrasive contact, and rodent activity. The flexible stainless steel braid withstands 1250N crush forces while maintaining signal integrity, eliminating premature failures that plague standard cables in harsh industrial settings. This protection proves critical in mining, steel production, and heavy manufacturing where cable damage represents the primary failure mode.

How does reverse mount configuration differ from standard forward-mount sensors?

Reverse mount positions the cable exit opposite to standard sensors, enabling installation in confined spaces where forward cable routing is physically impossible due to structural obstructions, adjacent equipment, or limited clearance. This orientation also provides superior vibration isolation by creating a mechanical decoupling point at the Lemo connector, reducing vibration transmission from machinery to cable and extending cable life in high-vibration applications like reciprocating compressors and impact crushers.

Can the CON021 converter interface with existing Bently Nevada monitoring systems?

Yes, CON021 output voltage ranges (-4V to -20V with -23V to -32V supply) match Bently Nevada 3300/3500 proximity probe systems, enabling direct connection to existing monitor inputs without signal conditioning. This compatibility supports phased migration from legacy systems, mixed-vendor installations, and retrofit projects where preserving existing monitoring infrastructure reduces project costs and complexity. Negative voltage convention and scale factor align with industry-standard proximity probe systems.

What is the maximum operating temperature for continuous sensor operation?

The PR6423 sensor head with PEEK tip operates continuously to +180°C (+356°F) for the first meter of cable near the sensing element, while the armored cable section and Lemo connector are rated to +150°C (+302°F). For applications exceeding these limits, consider the PR6453 high-temperature variant rated to +350°C, or implement heat shielding and forced air cooling to reduce sensor exposure temperatures below rated maximums.

How do I verify proper system calibration after installation?

Use precision gap gauges to measure output voltage at 0.5mm, 1.0mm, 1.5mm, and 2.0mm gaps from the target surface. With the 8 V/mm scale factor, voltage should change linearly by 4V, 8V, 12V, and 16V respectively from the initial gap reading. Deviations exceeding ±5% indicate calibration drift, cable damage, or improper target material. Document baseline calibration data for comparison during future maintenance inspections to detect gradual performance degradation.

What monitoring systems are compatible with CON021 converter outputs?

CON021 interfaces with Bently Nevada 3300/3500 systems, Emerson AMS Suite platforms, Rockwell PlantPAx DCS, Siemens SIMATIC PCS 7, Honeywell Experion PKS, and generic PLC/DCS analog input modules accepting ±10V or 4-20mA signals (with optional signal conditioning). The negative voltage output convention and high bandwidth support both legacy vibration monitoring systems and modern predictive maintenance platforms with advanced analytics capabilities.
