Spare electronic circuit board for B&G WS320 wind sensor

The B&G WS320 Spare PCBA is the replacement printed circuit board assembly designed specifically for the B&G WS320 wireless wind sensor. It is an essential internal component for maintaining the performance and reliability of the onboard wind measurement system.

This replacement PCBA is exclusively intended for the B&G WS320 wireless wind sensor. It is used to replace the internal printed circuit board of this specific model.

This PCBA is the central component enabling the WS320 sensor to provide:

A wind speed resolution of 0.05 m/sec (0.1 knot).
A wind speed accuracy of +/- 0.1 m/sec (0.2 knot) over a range of 1 to 40 m/sec (2 to 80 knots).
A wind speed range covered from 0.25 to 50 m/sec (0.5 to 97 knots).
A wind angle resolution of 0.1°.
A wind angle accuracy of +/- 0.5°.

The WS320 sensor, thanks to this PCBA, is designed to operate under harsh environmental conditions:

Operating temperature: -25°C to +60°CStorage temperature: -40°C to +85°CEnvironmental protection: IPx7 (waterproof)Humidity: 66°C, 95% RH, for 18 hours

The WS320 sensor is primarily powered by solar energy via an integrated panel and an internal battery. It can also receive 9-16 V DC power via the Micro-C network.

The WS320 sensor draws 1.2 W of electrical power, which corresponds to less than 100 mA at 12 V DC. The network load is 2 LEN (100 mA).

The WS320 sensor provides wireless connectivity with a range up to 30 meters (98 feet).

The WS320 transducer outputs apparent wind data (speed and angle) at a 5 Hz frequency.

The WS320 wind transducer weighs 0.32 kg (0.7 lbs).

The WS320 wind transducer dimensions are approximately Ø 90 mm (3.54") in diameter and 38 mm (1.50") in height.

No, the B&G WS320 Spare PCBA is specifically designed to be compatible only with the B&G WS320 wireless wind sensor. It is not compatible with other sensor models from the brand.

The WS320 sensor’s power and communication interface uses a Micro-C network, requiring a 9–16 V DC power supply.

Yes, the WS320 transducer is designed to use a 1.8 m (6 ft) Micro-C cable for its NMEA 2000 connection.

Replacing a printed circuit board is a technical operation that requires skills in electronics and handling delicate components. It is generally recommended to use a qualified professional for this task to ensure correct installation and avoid damaging the sensor.

Yes, precautions must be taken when handling electronic components. The technical document specifically mentions a warning about the risk of explosion if the battery is replaced with an incorrect type. Although this PCBA is a different component, caution is required with all internal sensor elements, particularly regarding static electricity and connections.

The technical document does not specify the exact tools required for replacing the PCBA itself. However, replacing a printed circuit board typically requires precision screwdrivers, antistatic tools, and potentially a soldering iron if components need to be desoldered/resoldered. It is advisable to consult the WS320 sensor service manual for detailed instructions.

No, the WS320 Spare PCBA is the spare printed circuit board assembly and does not include the internal battery of the WS320 sensor. The battery is a separate component that must be purchased if it also needs replacing.

After installing the new PCBA, it is essential to follow the test and configuration procedures for the WS320 sensor as described in the product’s full installation manual. This includes checking wireless connectivity, power supply, and correct transmission of wind data to ensure proper operation.

Replacing an internal component such as the PCBA can potentially affect the sensor's calibration. It is strongly recommended to consult the B&G WS320 sensor user manual for specific recalibration procedures after an internal part replacement to ensure wind measurement accuracy.

Yes, when replacing the PCBA, it is critical to ensure all gaskets and seals are correctly reinstalled and tightened to maintain the WS320 sensor’s IPx7 waterproof rating. Incorrect installation could compromise the sensor’s environmental protection and lead to water damage.
