Overview: The document provides technical specifications and features of the TG-8000 and TG-8500
gyrocompass models designed by Tokyo Keiki. These models are intended for standard IMO ship applications and high-speed craft applications, respectively.
Features:- Suitable for speeds up to 70 knots (TG-8500).
- Fast follow-up rate with a maximum of 75°/s.
- Fast serial data output compliant with IEC61162-2.
- Interfaces with external heading sensors.
- Minimal system components for dual gyro systems, optimizing space and installation costs.
- Startup-timer function for IMO regulated vessels (TG-8000) and High-Speed Craft (TG-8500).
Specifications:- Power Supply: Main power supply options include AC100/110/115/220 V 1φ50/60 Hz, with an emergency power supply of DC24 V.
- Power Consumption: Starting at 140 VA and operating at 70 VA.
- Output Signal: Includes DC24 V Stepper, IEC61162-1ed.2 or IEC61162-2, and rate of turn signals.
- Input Signal: Speed, position (GPS), and external heading input signals are supported.
Performance Specifications:- Settling time is less than 4 hours with a settling point error of less than ±0.3°.
- Repeatability is less than ±0.2°.
- Accuracy under environmental variation is less than ±0.5°.
Environmental Conditions: The permissible roll and pitch angle is ±45°.
