HIGH PRESSURE TRANSDUCER FOR HEAD-UP-DISPLAY DEVICE ON SELF CONTAINED BREATHING APPARATUS

摘要

Embodiments relate generally to methods, systems, and devices for monitoring and/or indicating the pressure levels within a self-contained breathing apparatus (SCBA) (100). Applicants have found that incorporation of a transducer system (300) into a high-pressure hose (120) of an SCBA (100) may be beneficial to monitoring and indicating the pressure level of air within the SCBA (100), wherein the high-pressure hose (120) may be coupled to a pressure gauge (118) and optionally a warning whistle (119). In some embodiments, a transducer (300) may be operable to sense or detect the pressure of high-pressure air flowing through the transducer (300). Additionally, the transducer (300) may comprise a processor (510) operable to transmit signal referencing the pressure to a heads-up display device (HUD) (140), wherein the HUD (140) may indicate the pressure level to a user of the SCBA (100).
