The GE TGT-S000-1-1 is a turbine governor transducer module under the TGT (Turbine Governor Transducer) series of General Electric (GE). It is specifically designed for speed monitoring and speed control of gas turbines, steam turbines, and hydro turbines. By measuring the rotor speed with high precision and transmitting signals to the speed control system, this module ensures the unit operates stably within the set speed range and prevents overspeed or underspeed faults.

• Real-time speed detection: Based on magnetoelectric or photoelectric sensing technology, with an accuracy of ±0.1% FS.
• Signal conditioning and output: Provides 4-20mA, pulse frequency, or Modbus signals, compatible with mainstream governors (e.g., Woodward 505).
• Fault self-diagnosis: Built-in health monitoring circuit, capable of detecting issues such as sensor disconnection and signal loss.

1. High-reliability speed monitoring:
   • With an accuracy of ±0.1%, it meets the requirements of the ISO 7919 vibration standard for steam turbines.
   • Resistant to oil pollution and dust (magnetoelectric type), suitable for the harsh environment of gas turbines.
2. Flexible output configuration:
   • Provides both 4-20mA (analog) and pulse signals (digital) simultaneously, compatible with old and new control systems.
   • Modbus RTU supports remote parameter configuration (e.g., range, filtering time).
3. Plug-and-play installation:
   • Fixed via M12 thread or flange; the probe gap can be fine-tuned with gaskets (0.5-1.0mm recommended).
   • Modular electronic unit, supporting DIN Rail or panel mounting.
4. Adaptability to harsh environments:
   • Wide temperature operation from -30°C to +85°C, with vibration resistance of 5g @ 1kHz.
   • The explosion-proof version (TGT-S000-1-1EX) has passed ATEX Zone 2 certification.
