Description

The BENTLY 136188-01 is an 8-slot monitor chassis designed for the Bently Nevada 3300 XL 1700/1800 series condition monitoring systems.This robust rack serves as the central housing for up to eight 3300 XL Proximitor®sensor conditioners,forming a complete vibration and position monitoring solution for rotating machinery.As a critical backbone in industrial asset protection,the BENTLY 136188-01 enables reliable,real-time monitoring of shaft vibration,axial position,eccentricity,and differential expansion in turbines,compressors,and large motors.

Application Scenarios

At a natural gas compression station in Alberta,Canada,operators faced recurring bearing failures due to undetected high vibration levels.The legacy monitoring system used standalone relays with no data logging or redundancy.By deploying a BENTLY 136188-01 8-channel chassis integrated with 3300 XL 1764 vibration monitors,the facility established a comprehensive protection layer.The BENTLY 136188-01’s modular design allowed simultaneous monitoring of radial vibration(X/Y axes)and thrust position across four compressor stages.Its dual redundant power supplies ensured continuous operation during utility fluctuations.When a misalignment event caused vibration to spike to 92μm,the BENTLY 136188-01-based system triggered an automatic shutdown within 200 ms,preventing catastrophic bearing damage.This incident saved over$500,000 in potential repair costs and unplanned downtime,demonstrating how the BENTLY 136188-01 transforms raw sensor data into actionable protection,ensuring asset integrity and operational continuity.

Technical Principles and Innovative Values

Innovation Point 1:The BENTLY 136188-01 features dual redundant power inputs,enabling seamless failover during power supply failure.This ensures uninterrupted monitoring of critical machinery,a vital feature in continuous-process industries like petrochemicals and power generation.

Innovation Point 2:Designed for hot-swappable module integration,the BENTLY 136188-01 allows technicians to replace or upgrade individual 3300 XL monitors(e.g.,1764 vibration modules)without shutting down the entire rack—minimizing risk and maximizing system availability.

Innovation Point 3:The BENTLY 136188-01 supports mixed module configurations,allowing combinations of vibration,displacement,speed,and temperature monitors in a single chassis.This flexibility enables tailored protection schemes for complex machinery trains.

Innovation Point 4:With a wide operating temperature range(-20°C to+65°C)and DIN rail mounting,the BENTLY 136188-01 is engineered for harsh industrial environments.Its modular,scalable design reduces panel space and simplifies system expansion compared to legacy discrete monitoring relays.

Application Cases and Industry Value

At a coal-fired power plant in South Korea,turbine-generator sets required reliable shaft vibration monitoring to prevent catastrophic failures.The plant replaced aging analog systems with a BENTLY 136188-01 chassis housing eight 3300 XL 1764 vibration monitors.The system detected a gradual increase in bearing vibration over three weeks,allowing planned maintenance before failure.The BENTLY 136188-01’s integration with the plant’s DCS via 4–20 mA outputs enabled real-time trending,contributing to a 30%reduction in unscheduled outages.Operators reported high confidence in the system’s reliability and ease of diagnostics.

In an offshore oil platform’s gas injection compressor station,space and reliability are paramount.The BENTLY 136188-01 was chosen for its compact DIN rail footprint and redundant power design.It monitored four compressor trains with full vibration and position coverage.During a lightning strike,one power supply failed,but the redundant input kept the BENTLY 136188-01 operational,preventing a false trip.The platform’s maintenance team credited the BENTLY 136188-01 with improving safety and reducing spare parts inventory due to its modular,repair-friendly architecture.
