System: All 3500 monitors (vibration, speed, temperature)

Core Functions

Multi‑Parameter Monitoring: Each channel pairs with another (1&2, 3&4) for dual functions (e.g., vibration + thrust).

Precision Signal Conditioning: High‑gain, low‑noise circuitry for accurate gap/ vibration measurements.

Flexible Alarm Configuration: Independent Alert/Danger setpoints; voting logic with other rack modules for shutdowns.

Diagnostics & Bypass: Self‑check, probe fault detection, and channel bypass for maintenance.

Industrial‑Grade Reliability: Epoxy‑coated, wide temperature range, hot‑swappable.

Applications

Power Generation: Steam/gas turbines, generators, BFP (boiler feed pump) shaft vibration/thrust monitoring.

Oil & Gas: Centrifugal compressors, pumps, turbines, refinery rotating equipment protection.

Heavy Industry: Large motors, gearboxes, fans, and process machinery condition monitoring.

TSI Systems: Turbine Supervisory Instrumentation for critical rotating assets.

Predictive Maintenance: Early fault detection (rubbing, misalignment, bearing wear) via continuous vibration/trend data.
