6 Advantages of Blue Guard Innovations BG-SWA over Ultra Safety Systems Senior
That’s it, you have had it with traditional float switches breaking but you can’t decide if the Ultra Safety Systems Senior or the Solid-State Bilge Pump Switch with High Water Alarm (BG-SWA) is right for your boat. Before you invest in your next bilge float switch consider these six items.
1. Activation Level & Remaining Bilge Water
Even with the Ultra Safety Systems Senior mounted as low as possible, it requires a minimum of 2.5 inches of water to activate. The Ultra Safety Systems Senior then deactivates the pump when there is still 1.5 inches of water left. On the other hand, the BG-SWA with its adjustable pump run time will pump out as much water as possible. The BG-SWA also has a very precise activation point, meaning that it will activate the pump within 1mm every time. If you wanted to, you could mount the BG-SWA to the bottom of your bilge and it would activate with as little as 0.25 inches of water - you just need to make sure that your pump is self-priming.
2. High Water Alarm
Both the Ultra Safety Systems Senior and the BG-SWA have built in high water alarms. The Ultra Safety Systems Senior will alarm once water reaches 1 inch above its pump activation point. When mounted as low as possible this is a minimum of 3.5 inches. The BG-SWA will alarm if it continues to see water after activating the pump - within 3 seconds you will know that something is wrong.
3. Max Current and Operating Voltage
When looking at the Ultra Safety Systems Senior you will need to select between one that is 12 Vdc or one that is 24, 32 Vdc compatible. They don’t have one that can handle all three voltages. The 12 Vdc model can handle up to 15 Amps max while the 24 and 32 Vdc models can handle 10 Amps. On the other hand, the BG-SWA is universal and can be connected to any 12, 24 or 32 Vdc system. When the BG-SWA is connected to a 12 Vdc system it will handle 20 Amps, on a 24 Vdc system it will handle 15 Amps, and on a 32 Vdc system it will handle 10 Amps.
I know what you are thinking, why do I need Bluetooth inside my bilge? Consider this, you want to test your switch to ensure it’s working properly. However, that requires you to crawl down into the bilge and you hate going down there. In order to test the Ultra Safety Systems Senior you first have to go down into the bilge but also figure out how to move the plunger without disconnecting the entire unit. To test the BG-SWA simply get your phone out and download the BGI Config app, no more crawling around in the bilge.
The Ultra Safety Systems Senior is considered a mechanical float switch because of its moving parts. When a switch has moving parts it runs the risk of being jammed. The BG-SWA is a solid-state switch meaning it has no moving parts that can get jammed or broken.
6. Alarm Output
Both the Ultra Safety Systems Senior and the BG-SWA have built in high water alarms. The Ultra Safety Systems Senior’s alarm circuit is based on either Normally Open or Normally Closed contacts with a current limit of 100 mA. The BG-SWA on the other hand has an ‘active’ alarm that can directly drive anything up to 1 Amp, such as a horn, buzzer and/or light.
Overall if you are considering upgrading your bilge, the BG-SWA is the best option. Its low activation level, testability via the BGI Config app and no moving parts make it a no brainer.
