Overview
The B&G 000-11552-001 is a H5000 barometric pressure sensor that sends atmospheric pressure readings to the instrument network for trend tracking and onboard weather awareness.
It reports pressure with 0.1 mb resolution over an industry-standard CAN network and is powered through the network at 12 V nominal (9-16 V). The module measures 61 x 131 x 45 mm (2.4 x 5.2 x 1.8 in), which fits well behind panels or in other protected interior mounting spots.
Key features
- Barometric pressure measurement with 0.1 mb resolution for monitoring pressure trends on the water
- CAN network connection suitable for H5000 systems, with power delivered through the network
- 12 V nominal supply via network (9-16 V operating range) with typical draw under 50 mA (1 LEN equivalent)
- Compact housing size: 61 x 131 x 45 mm (2.4 x 5.2 x 1.8 in)
- Reverse-polarity protection to help reduce risk during installation and commissioning
- ABS plastic housing intended for protected mounting locations
Compatibility and fit
This sensor is intended for B&G H5000 instrument networks that distribute data over a CAN backbone. Once installed, the pressure value is available anywhere on the network for compatible displays and system functions that use environmental data.
Because it is network-powered, plan for a properly powered instrument backbone in the 9-16 V range. On vessels with 24 V house systems, the backbone still needs a 12 V feed, as is typical for NMEA 2000-style networks.
Installation and setup
Mount the sensor in a protected location where cabin air can reach it. Avoid sealing it inside an airtight locker, and keep it away from direct spray and areas that see rapid temperature swings, since those conditions can make pressure trends less useful.
After wiring it into the network, verify the sensor appears on the system and select it as the barometric pressure source in your H5000 setup so the reading is consistent across displays and pages.
Use cases on board
Pressure trends are handy for coastal cruising and offshore passages when you want an early warning that conditions are changing, as well as for race programs that keep an eye on subtle weather shifts.
This sensor is a practical add-on for boats already running an H5000 instrument suite and looking to keep pressure data inside the same network as wind, speed, and heading.
Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.
Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.
Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.
Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.
