Key Features
Advanced Shaft Absolute Vibration Monitoring
Designed specifically for the Bently Nevada 3500 system, this module provides precise shaft absolute vibration monitoring by combining casing vibration compensation (seismic) with shaft relative vibration (proximity) to capture the true movement of critical rotating machinery.
4-Channel Transducer Signal Conditioning
Features a high-density 4-channel vibration inputs interface. It delivers robust transducer signal conditioning for a wide range of industrial sensors, providing seamless proximity and seismic interface capabilities on a single machinery protection card.
Integrated Internal Terminations Design
Equipped with factory-installed internal terminal block wiring, eliminating the need for separate external terminal blocks or specialized interface cables. This internal terminations module ensures secure, direct-to-board field wiring, significantly reducing installation time and footprint in the Bently Nevada 3500 rack module.
Seamless 3500/42M Monitor Integration
Engineered as the dedicated rear I/O pairing for the 3500/42M Proximitor Monitor. It works in perfect synergy with the 3500/22M Transient Data Interface (TDI module integration) and 3500/01 configuration software for comprehensive data acquisition and diagnostics.
API 670 Compliant Critical Asset Protection
Fully compliant with industry-standard API 670 mandates for critical asset protection. It provides reliable, high-isolation vibration signal isolation and connects flawlessly to emergency shutdown systems (ESD) to prevent catastrophic failures.
Heavy-Duty Industrial Application
Built to withstand harsh environments (-30°C to +65°C), making it the ideal choice for steam turbine shaft monitoring, gas turbine protection systems, large centrifugal compressors, and power plant instrumentation.
Industrial Applications
- Critical Steam Turbine Shaft Monitoring - In steam turbine applications, the Bently Nevada 138708-01 / Shaft Absolute I/O Module is commonly used in power plant instrumentation. It handles shaft absolute vibration monitoring and radial vibration measurement across start-up, load changes, and steady operation. Working within 3500/42M systems, it supports machinery protection card level monitoring and helps detect abnormal shaft behavior early.
- Heavy-Duty Gas Turbine Protection Systems - For gas turbine protection system use, the module focuses on vibration anomaly detection and feeds signals into emergency shutdown system (ESD). With transducer signal conditioning and vibration signal isolation, it keeps data stable even in harsh electrical environments, helping reduce risk of equipment failure or unplanned shutdowns.
- Large Centrifugal Compressor Vibration Monitoring - In centrifugal compressor monitor setups, it works with proximity and seismic interface sensors to track shaft eccentricity and thrust position. Commonly used in oil & gas and petrochemical rotating machinery protection systems, it supports 4-channel vibration inputs for multi-point monitoring.
- API 670 Compliant Critical Asset Protection - As part of the Bently Nevada 3500 rack module family, the 138708-01 is widely applied in API 670 compliant systems for critical asset protection. It provides basic diagnostics and interlocking functions and integrates through 3500/01 configuration software into broader 3500 monitoring system spares architecture.
- Hydroturbine Absolute Shaft Vibration Analysis - In hydroturbine applications, it is used for absolute shaft vibration monitoring combined with casing vibration compensation. It helps identify hydraulic imbalance and misalignment issues, especially under low-frequency operating conditions typical in hydro units.
- Plant-Wide 3500 Monitoring System Spares Integration - The module fits directly into existing 3500/42M Proximitor Monitor systems and works with TDI module integration and 3500/22M Transient Data Interface setups. As part of 3500 monitoring system spares, it can be replaced quickly and reintegrated into the rack without major system changes.
Frequently Asked Questions
Q1: What is the primary function of the Bently Nevada 138708-01 I/O module?
The Bently Nevada 138708-01 / Shaft Absolute I/O Module is a 4-channel module used for transducer signal conditioning in industrial rotating machinery protection. Installed in the rear slot of a Bently Nevada 3500 rack module, it takes inputs from proximity and seismic sensors and works with the monitor to calculate shaft absolute vibration monitoring by combining relative shaft motion with casing vibration data. In practice, it’s a key part of critical asset protection for high-speed equipment.
Q2: How does the internal terminations design of the 138708-01 benefit system installation?
The 138708-01 uses an internal terminal block wiring structure, basically an internal terminations module. Field wiring connects directly to screw terminals on the back of the card, so there’s no need for external terminal blocks or extra interface cables. That usually means less cabinet space, fewer wiring points that can fail, and a simpler setup for power plant instrumentation.
Q3: Which Bently Nevada 3500 monitors and systems are compatible with the 138708-01?
It is mainly designed to pair with the 3500/42M Proximitor Monitor, and it also fits within systems supporting 3500/40M configurations. Through the rack, it supports TDI module integration via the 3500/22M Transient Data Interface, while configuration and alarm settings are managed in 3500/01 configuration software. Everything stays within the standard 3500 monitoring system spares architecture.
Q4: What types of machinery measurements can be processed through the 138708-01?
Beyond shaft absolute vibration, the module can handle radial vibration monitoring, shaft eccentricity tracking, thrust position measurement, and differential expansion monitoring. With its 4-channel design, it supports multiple vibration inputs, making it suitable for machinery protection card applications and API 670 compliant systems.
Q5: In what industrial applications is the 138708-01 typically deployed?
You’ll usually find the 138708-01 in steam turbine shaft monitoring and gas turbine protection systems in power plants. It’s also widely used in centrifugal compressor monitor setups in oil & gas and petrochemical industries, and in hydroturbine absolute shaft vibration monitoring. In all these cases, it contributes to emergency shutdown system (ESD) logic when vibration limits are exceeded.
Q6: Why is the 138708-01 heavily stocked as part of plant-wide 3500 monitoring system spares?
Because 3500/42M-based systems are widely installed in global power and process industries, the 138708-01 is often kept as part of 3500 monitoring system spares. Having ready stock means operators can replace or hot-swap the module quickly if an internal terminations module or sensor interface fails, keeping machinery protection active and avoiding unplanned downtime.
