Turbine & Rotating Machinery Temperature Monitoring Solution — Bently Nevada 3500/60 | 133811-01
Where This Product Is Used
The Bently Nevada 3500/60 Temperature Monitor Module (P/N 133811-01) is purpose-built for continuous temperature monitoring in critical rotating machinery protection systems. Typical deployment environments include:
- Gas & Steam Turbines — bearing temperature surveillance in power generation plants (combined-cycle, simple-cycle, cogeneration)
- Centrifugal Compressors — monitoring journal and thrust bearing temperatures in upstream oil & gas compression trains
- Large Induction Motors & Generators — winding and bearing temperature protection in petrochemical and refinery drives
- Pumps & Fans (Critical Service) — high-availability process pumps in LNG, refining, and chemical plants
- Marine Propulsion Systems — shaft bearing temperature monitoring on LNG carriers and FPSO vessels
- Reciprocating Compressors — cylinder and packing temperature monitoring in gas processing facilities
Wherever API 670 machinery protection is mandated, the 3500/60 is the industry-standard temperature monitoring card within the Bently Nevada 3500 rack system.
