CWZ-2 Wall Type Sensor
Product Description
CWZ-2 Wall Type Sensor
Product Introduction:
Our Marine Sensor for Propeller Revolution Indicator is a precision-engineered component designed to provide accurate and reliable rotation speed detection for ship propulsion systems. Built to endure the most demanding maritime conditions, this sensor delivers the critical data needed to monitor propeller performance, optimize engine efficiency, and ensure safe vessel operations.
Constructed with a robust, watertight housing (IP67/IP68 rating) made of marine-grade stainless steel, the sensor offers exceptional resistance to corrosion, vibration, moisture, and temperature extremes. Its non-contact detection technology—using advanced magnetic or inductive principles—ensures precise and stable signal output by generating clean pulse signals for each shaft revolution. This design eliminates mechanical wear, ensuring long-term reliability and low maintenance.
The sensor is designed for easy installation and flexible integration. It features a compact form factor with standard mounting options (e.g., flange or threaded mount) and compatibility with common shaft configurations. Output signals (such as NPN/PNP open collector or Namur) can be directly connected to propeller revolution indicators, data loggers, or integrated bridge systems. This versatility makes it suitable for various marine applications, including commercial vessels, workboats, and offshore platforms, wherever precise speed monitoring of propeller shafts is essential.
In summary, our sensor serves as the vital link in marine propulsion monitoring systems, providing the high-integrity input required for efficient and safe vessel management.
