CWZ-1 Propeller Revolution Indicator

CWZ-1 Propeller Revolution Indicator

Product Introduction

The Propeller Revolution Indicator is an essential marine instrument designed to provide accurate, real-time monitoring of a vessel's propeller shaft rotational speed, displayed in Revolutions Per Minute (RPM). This critical data is fundamental for bridge officers and engineers to assess propulsion efficiency, optimize engine load, and ensure safe, economical operation across all sailing conditions.

Engineered for the demanding marine environment, the indicator receives signals from a tachometer sensor mounted on the propeller shaft. It processes and displays this information on a clear, easy-to-read interface—available in robust analog dial or modern digital formats—often featuring high-visibility lighting for night operations. By delivering instant feedback on shaft speed, it enables precise throttle control during maneuvering, aids in fuel optimization during cruising, and serves as a vital safeguard against engine and propulsion system overload.

Housed in a durable, corrosion-resistant casing suitable for panel mounting, this instrument is built to withstand constant vibration, humidity, and temperature fluctuations. Its reliability makes it a cornerstone for efficient voyage planning, mechanical system protection, and overall navigational safety on all types of commercial and recreational vessels.
