Senzor kompasu fluxgate

The T909 fluxgate compass sensor provides accurate and reliable magnetic heading data to your navigation system. This information is essential for true wind calculation, leeway correction, and basic operation of compatible autopilots.

The T909 is specifically designed for use with Raymarine Tacktick Micronet wireless instrument systems. It is a wired sensor that connects to a hull transducer (such as the T121) to broadcast data over the wireless network.

For optimal accuracy, the sensor must be installed:

As low as possible in the boat and near the center of gravity.On a horizontal and stable surface.Away from any magnetic interference sources such as engines, speakers, high-current cables, metal tanks, or other electronic equipment.

No, the T909 uses traditional fluxgate technology that measures magnetic heading only. The Raymarine EV-1 is a 9-axis attitude reference unit that measures heading, pitch, roll, and yaw, providing more comprehensive data for modern autopilots.

Yes, absolutely. A calibration procedure is essential after installation. It allows the compass to compensate for the boat's own magnetic fields (deviation), ensuring that the displayed heading is as accurate as possible.

The T909 fluxgate compass sensor weighs 95 g, making it easy to install in various onboard locations.

No, the T909 cannot be directly connected to an NMEA 2000 or SeaTalkNG network. It is designed to connect to a hull transducer in the Tacktick Micronet system, which then broadcasts the data.

The T909 sensor is a wired device. It is powered via the cable connecting it to the hull transducer of the Tacktick Micronet system. It does not require a battery or separate power supply.

Yes, the T909 is the ideal replacement part to swap out a faulty fluxgate compass sensor within an existing Tacktick Micronet instrument installation, allowing you to keep your system operational without replacing everything.

A fluxgate compass like the T909 measures the Earth's magnetic field to determine heading. A GPS compass calculates heading based on changes in its position (COG - Course Over Ground). The fluxgate compass is more accurate at low speed or when stationary, which is critical for harbour manoeuvres or calculating true wind while anchored.

No, the fluxgate compass sensor can be oriented in any direction as long as it is mounted on a vertical surface. The arrow on the sensor must point upward, not toward the bow of the boat.

Yes, this sensor can provide the basic heading data required for some older autopilot systems that are compatible with Tacktick Micronet networks.

No, the T909 is a fluxgate compass that only measures magnetic heading. It does not include accelerometers or gyroscopes to measure heel or pitch.

Signs of a faulty compass may include an unstable heading, significant and inconsistent heading errors, or a complete loss of heading data on your displays. If calibration does not resolve the issue, replacement is often necessary.

No special tools are required. Installation requires basic tools for drilling and securing the bracket, as well as for connecting the cable to the hull transducer. The main challenge lies in selecting the correct location.

This product is sold under the Raymarine brand. Raymarine acquired the company Tacktick and continues to produce components for these popular systems, such as this T909 sensor.

The fluxgate compass sensor is designed to be installed inside the boat, in a dry and protected location. It is not intended for outdoor installation or direct exposure to water.

The navigation system uses the magnetic heading provided by the T909 and the boat’s speed to convert the apparent wind measurement (direction and speed measured by the wind transducer/vane anemometer) into true wind. Without an accurate heading, calculating true wind would be impossible.

This is not its primary purpose. The T909 is designed to natively integrate into the Tacktick Micronet ecosystem via its transmitter. Using it with other brands would require a specific interface and advanced technical knowledge, and is not guaranteed.

Like any electronic instrument, it is designed to operate within the normal temperature range found inside a boat. It should not be installed near an intense heat source (engine compartment, heater) that could affect its performance and lifespan.
