YDK Tech CMZ900S

The YDK Tech (previously Yokogawa) CMZ900 Series of Gyro Compasses offers several models tailored to meet the diverse needs of various vessels. These models have been type-approved to comply with IMO standards resolution and JIS-F9602 Class A standards. A gyro compass detects true north using a fast-spinning rotor suspended without friction and influenced by gravity and the Earth’s rotation, providing an accurate indication of a ship’s heading.

CMZ900 Series Gyro Compasses Overview

The CMZ900 series has been type-approved in accordance with International Maritime Organization (IMO) standards, resolution A.424(XI), and JIS-F9602 Class A standards. One of the notable models in this series is the CMZ900-S Gyro Compass, which includes a control box with a built-in monitor, suitable for all merchant vessels, and offers various types of signal outputs.

What’s Inside the Box

• Master compass
• Master operation unit with gyro heading indicator and alarm panel
• Switch unit (power switch unit)
• Control box
• C. operation unit
• Gyro sphere
• Standard spare parts
• Installation kit
• Spare supporting liquid
• Final drawings (3 sets)
• Instruction manuals (3 sets)

Technical Specifications

The system configuration can easily be adapted to the vessel’s specifications. The CMZ900 series offers IEC 61162-2 high-speed code for heading and rate of turn (ROT) outputs. A unique anti-vibration system, enhanced by the velocity damping effect of high viscous oil, provides superior damping of vibration and decoupling of shock at sea. The small and lightweight container enhances the follow-up speed, allowing the gyro compass to change smoothly without lag, even if the vessel rapidly changes course.

This space-saving device can be installed on the autopilot stand, and the restart time can be preset from 1 to 99 hours. Additionally, the Bridge Alert Management System (BAMS) interface function is based on IEC62288 Ed. 2 standards.

Settling Time and Accuracy

• Within 5 hours – operational state is reached in about 2 hours.
• Static: +/- 0.25 deg x sec
• Dynamic: +/- 0.7 deg x sec
• Follow-up accuracy: 0.1 deg or less

Power Supply

The main power supply for the CMZ900 series is 24 V DC. An optional AC adapter (type MKS070) is available for 100V/110V/115V/220V AC 50/60Hz single phase power sources.

Conclusion

The YDK Tech CMZ900 Series Gyro Compasses are highly reliable and precise, making them an essential component for modern maritime navigation. With their compliance with international standards, advanced features, and robust design, they ensure accurate heading information and enhance the overall safety and efficiency of marine operations.
