Turbine Supervisory Instrumentation

Sentry G3 – Full API 670 Compliant Monitoring System

The Sensonics API670 compliant Sentry G3 system is ideally suited for your turbine supervisory measurement requirements. The independent channel digital signal processing and dual redundant power supply functionality provide flexibility with reliability. Voted channel arrangements can be configured to provide robust solutions for speed and shaft position monitoring in compliance with the API670 standard.

Sentry G3 Measurement
Modes

The Sentry G3 universal hardware concept allows any channel to be programmed to the required measurement regime. Providing maximum flexibility within a single module type. The G3 module contains all alarm relays, analogue output and digital communication functionality. No other additional module types are required in the rack, reducing common-mode failures, and the required variants of operational spares.
