Detailed description

The Raymarine T120 wireless masthead sensor is a wind transducer designed to provide accurate wind speed and angle data to navigation instruments. It stands out for its simplified installation at the masthead, eliminating the need for complex cabling thanks to its wireless connectivity. This system is compatible with Raymarine displays, allowing immediate visualization of critical navigation information for sailing.

Installation and positioning

The T120 is intended to be mounted at the masthead, with the transducer head positioned forward and the vane precisely aligned with the boat's longitudinal axis. Installation requires drilling three 4 mm holes to secure the provided mounting bracket. The wind transducer is then inserted into this bracket and secured with a bolt. Initial calibration is required after installation to ensure the accuracy of apparent wind speed and angle measurements.

Maintenance and durability

The Raymarine T120 design includes user-replaceable components, including the vane, anemometer cups, and bearing assembly. This modularity enables easy maintenance and extends the sensor's lifespan. The T120 complies with FCC (Part 15) and Industry Canada (RSS) regulations, ensuring reliability in terms of emissions and immunity to interference. Unlike CPT-80 or CPT-120 transducers, which are through-hull depth sounders, the T120 is specifically an air wind sensor. It positions itself as an alternative to wired wind sensors, commonly found in instrument ranges from competing brands such as B&G or Garmin, offering increased installation flexibility for recreational sailboats.

« Technical analysis: Raymarine T120 wireless wind sensor »

The Raymarine T120 wireless aerial sensor is a practical solution for acquiring wind data at masthead level. Its main advantage lies in its wireless architecture, which eliminates the need to run a cable through the mast. This feature significantly simplifies installation, particularly on existing sailboats where routing a new cable can be complex and costly. This sensor is ideal for mid-sized pleasure sailboat owners looking to upgrade or replace their wind sensor with minimal rigging work.

Physical installation at masthead, while requiring a climb, is made easier by the supplied mounting kit. It is crucial to ensure precise alignment of the vane with the boat's longitudinal axis to guarantee accurate wind angle measurements. Post-installation calibration is essential for reliable data. The ability to replace wear parts such as the vane and anemometer cups is a notable advantage in terms of durability and long-term maintenance cost, allowing only the mechanical components exposed to environmental stresses to be replaced.

It is important to note that the T120, as a wireless sensor, must integrate into a compatible Raymarine instrument network for data visualization. It is not a standalone system but a component of a navigation ecosystem. Unlike vertical wind sensors such as the T222, often preferred for tall masts or specific racing applications, the T120 offers a more common horizontal format, suitable for a wide range of sailboats. Before installation, check compatibility with existing displays and plan the calibration procedure.

Frequently Asked Questions

Need help? Contact us

What is the primary function of the Raymarine T120 wireless masthead transducer?

The Raymarine T120 wireless masthead transducer is a wind transmitter designed to measure and provide accurate data on wind speed and angle. This information is then wirelessly transmitted to compatible navigation instruments, allowing navigators to view apparent wind conditions in real time.

What are the advantages of a wireless wind sensor like the Raymarine T120?

The main advantage of the Raymarine T120 sensor is its simplified installation. Being wireless, it eliminates the need to run complex cables through the mast, making masthead mounting much easier. This provides greater flexibility and reduces installation time and complexity compared to traditional wired systems.

How should the Raymarine T120 masthead wind transducer be positioned on the mast?

The T120 wind transducer must be mounted at the masthead. It is critical that the transducer head faces forward and that the vane is precisely aligned with the boat's longitudinal axis (bow-to-stern). This positioning ensures accurate wind angle measurements.

Which tools are required to install the T120 wind transducer?

For installing the Raymarine T120 wireless aerial wind transducer, the following tools are required:

An electric drillA 4 mm drill bitA Phillips screwdriver

Which parts are supplied with the Raymarine T120 wireless aerial sensor for installation?

The Raymarine T120 wireless masthead sensor comes with the following parts to simplify installation:

A masthead mounting bracketThree mounting screwsThe wind transducer (the sensor itself)A mounting boltNote that depending on the masthead plate, alternative mounting screws or bolts may be required.

Does the T120 sensor require calibration after installation?

Yes, to ensure measurement accuracy, the T120 wind transducer must be calibrated before use. The calibration and alignment process is detailed in your Raymarine navigation instrument manual.

Which systems or displays is the Raymarine T120 wireless masthead sensor compatible with?

The Raymarine T120 wireless masthead sensor is compatible with Raymarine displays. It is designed to provide wind speed and angle data to these instruments, enabling immediate display of critical sailing navigation information.

Is it possible to replace components of the T120 sensor in case of wear?

Yes, the Raymarine T120 design includes user-replaceable components. In case of wear or damage, you can replace the vane, anemometer cups, and bearing assembly. For installation details of these spare parts, refer to the user manuals provided with the replacement items.
