Detailed description
Detailed description
The **SEN-INSRT-SP2** speed sensor valve is a B&G replacement part for paddlewheel speed transducer installations. Integrated into a through-hull fitting, this valve allows for the safe insertion and removal of the transducer for maintenance, even when the boat is afloat. This model is the screw-on version, using a threaded mechanism to hold the sensor in place.
Compatibility and installation
This valve is designed for B&G paddlewheel speed sensors, including those used with Hydra and Hercules navigation systems. It is an integral part of a through-hull fitting that allows the paddlewheel to make direct contact with the water flow for accurate speed measurement. Since B&G has produced through-hull fittings in different diameters (e.g., 31 mm and 40 mm) over time, it is essential to verify dimensional compatibility with your existing installation before purchasing.
Design for maintenance
The component incorporates a self-sealing valve, often called a flapper valve. This mechanism is designed to minimize water entry into the hull when the speed sensor is removed. This feature greatly facilitates essential maintenance operations, such as cleaning the impeller, which must be free of marine fouling to provide reliable speed data.
