Bently Nevada 135137-01 Position I/O Module with Internal Terminations
The Bently Nevada 135137-01 is a 4-channel Position I/O Module with internal terminations for the 3500/45 system. It provides precise axial thrust and differential expansion monitoring for critical turbines, featuring a rugged design certified for temperatures up to +85°C.
High-Precision Displacement Monitoring and System Interface
The Bently Nevada 135137-01 drives critical displacement monitoring within the 3500 Machinery Protection System. This I/O module resides in the rear of the 3500 rack and interfaces directly with the 3500/45 Position Monitor. By processing signals from proximity probes and Rotary Potentiometers, the module enables the tracking of axial thrust position, differential expansion, and valve opening measurements. This real-time data allows the system to execute automatic machinery trips if shaft movement exceeds safety limits, effectively preventing catastrophic internal contact between rotating and stationary turbine components.

Predictive Maintenance and Asset Reliability
The 135137-01 advances predictive maintenance (PdM) strategies by delivering precision insights into machinery geometry and thermal growth. The internal termination design simplifies cabinet architecture, allowing technicians to land field wiring directly onto the module without requiring external terminal blocks. Furthermore, the module maintains high signal integrity in high-EMI environments, ensuring that the 3500/45 monitor receives an accurate, noise-free displacement signal. This reliability is vital for the safe operation of:
- Steam turbine thrust bearing wear monitoring
- Gas turbine case expansion and alignment
- Hydro-turbine wicket gate position tracking
- Boiler feed pump shaft axial position monitoring
Installation and Field Integration
Maintenance teams install the 135137-01 in the rear slot directly corresponding to the 3500/45 monitor card. Because it features internal terminations, the module provides a compact, space-saving solution for high-density monitoring racks. The integrated screw terminals accommodate shielded, twisted-pair cabling, which effectively reduces the risk of ground loops and electromagnetic interference. Additionally, the module is hot-swappable, empowering technicians to perform maintenance or upgrades without interrupting the operation of other healthy monitoring channels within the same 3500 chassis.
