Abstract: A transmitter assembly with redundant pressure value indicator for a self-contained breathing apparatus is provided. The transmitter assembly with redundant pressure value indicator includes a wireless transmitter configured to transmit gas pressure data for a gas storage tank to a dive computer. The gas pressure data is retrieved from a pressure sensor coupled to the wireless transmitter. The transmitter assembly with redundant pressure value indicator also has a visual indicator configured to indicate a gas pressure value for gas in the storage tank. The visual indicator and wireless transmitter are coupled to a control module. Further, the wireless transmitter, control module, and visual indicator share a power source.
