EV1 Evolution arvutusandur

The EV1 Evolution sensor (part number E70096) is the decision-making core of Raymarine autopilot systems. It replaces older compasses and integrates a 9-axis attitude and heading reference system (AHRS) to monitor boat movements in three dimensions.

Unlike traditional fluxgate compasses that require complex calibration procedures at sea, the EV1 sensor uses semiconductor technology with automatic linearization. It adapts in real time to navigation conditions and the boat's dynamics.

No, no complex manual calibration is required. The EV1 sensor integrates automatic linearization technology that calibrates itself during your sailing, greatly simplifying the commissioning of the autopilot.

The EV1 sensor is fully compatible with Raymarine autopilot control heads, including the p70s, p70Rs models, as well as older generations p70 and p70R.

The sensor can be installed indoors or outdoors. It is recommended to place it in a clear area, at least 1 meter away from VHF or radio cables, and more than 2 meters from the beam of a radar or HF radio to avoid electromagnetic interference.

Yes, the EV1 sensor is IPX6 and IPX7 certified, making it fully waterproof against powerful spray and temporary immersion. It can therefore be installed outdoors on deck without any risk.

The 9-axis AHRS (Attitude Heading Reference Sensor) technology combines a 3-axis digital accelerometer and semiconductor sensors. This enables the autopilot to measure the vessel's heading, pitch, roll, and yaw with extreme precision.

The EV1 sensor is powered directly by the SeaTalkNG network. It does not require a dedicated power cable but connects via a spur cable to the network backbone.

The EV1 sensor natively communicates via Raymarine’s SeaTalkNG protocol. It is also compatible with NMEA2000 networks when using the appropriate adapter cable.

No, the EV1 sensor is designed as the standard choice for mechanical and hydraulic autopilot systems (paired with an ACU power unit). For Drive-by-Wire steering systems, the specific EV2 model must be used.

The EV1 sensor is very energy-efficient. It draws only 30 mA on the SeaTalkNG network (LEN of 1), with an operating voltage range from 10.8 V to 15.6 V DC.

To ensure optimal accuracy, the sensor must be installed at least 1 meter away from any equipment transmitting radio signals (such as a VHF) and more than 2 meters from the path of a radar beam or SSB radio.

The EV1 sensor housing is very compact. It has a diameter of 140 mm. Its depth is 35 mm for flush mounting, and 95 mm if installed on its wall bracket.

Yes, the EV1 sensor offers flexible mounting options. It can be installed flush on deck or mounted on a vertical bulkhead using the supplied wall-mount bracket.

For the automatic linearization procedure to run correctly, the boat must be sailing at a speed between 3 and 15 knots. If the speed falls outside this range, the process is temporarily paused.

The EV1 sensor operates in conjunction with Evolution series actuator control units (ACUs). It is compatible with models ACU-100, ACU-150, ACU-200, ACU-300, and ACU-400, depending on your boat’s size and steering type.

If navigation conditions become unfavorable (for example, a speed below 3 knots), the automatic linearization process simply pauses. It will resume automatically as soon as the required conditions are met again.

The sensor connects to the network via a SeaTalkNG spur cable. It is usually supplied with a 1-meter cable, but different lengths can be used depending on your installation's specific requirements.

Absolutely. With its 9-axis attitude sensors, the EV1 continuously monitors pitch, roll, and yaw. This allows the autopilot to react instantly and maintain a precise heading even in rough seas.

Yes, although it uses Raymarine-specific SeaTalkNG connectors, the communication protocol is based on the NMEA2000 standard. Simply use a SeaTalkNG to DeviceNet (NMEA2000) adapter cable to integrate it into an existing NMEA2000 network.
