Product Overview
Bently Nevada 170190‑01E (1034549‑42) is dual‑channel proximitor monitor module belonging to 1701 FieldMonitor distributed machinery protection system. It receives voltage signals from eddy‑current proximitor probes, performs signal conditioning, filtering and linearization, outputs radial shaft vibration and thrust‑bearing axial‑gap position values. Each channel supports independent Alert and Danger alarm thresholds with configurable time‑delay to avoid false tripping. Built‑in continuous self‑diagnosis detects probe failure, cable open‑circuit/short‑circuit and module internal faults. Hot‑swap design allows module replacement without rack power‑off. It reduces long‑distance analog field‑cable interference for skid‑mounted rotating‑machinery. It addresses typical pain‑points: vibration signal distortion caused by long field wiring, unreliable probe‑cable health diagnosis, false‑alarm triggered by transient mechanical spikes. Rotating‑machinery engineers, vibration‑commissioning technicians and plant‑maintenance teams benefit from this unit. It applies for distributed machinery‑protection projects and drop‑in spare‑part replacement for existing 170190‑01E installations.
Application Scenarios
- Gas‑turbine & centrifugal‑compressor skid‑mount protection: Local signal conditioning for shaft radial vibration and thrust‑position monitoring on compressor skids, distributed machinery protection.
- Thermal‑power‑plant steam‑turbine generator monitoring cabinets: Monitors bearing vibration and axial thrust displacement for turbine‑generator sets.
- Oil‑&‑gas compressor‑station rotating‑equipment: Field‑side processing of proximitor signals, shortens analog‑cable length and suppresses electromagnetic interference.
- Industrial captive‑power‑plant turbo‑generator condition‑monitoring: Implements protection‑logic for backup turbo‑units.
