Air pressure gauge with self contained adjustable alarms
摘要
A diver's air tank pressure gauge having audible and visual alarms, an alarm pointer for indicating the pressure at which the alarms will activate, and a crank assembly for changing the position of the alarm pointer. The pressure gauge dial has a cutout for limiting the travel of the alarm pointer between acceptable high and low pressure limits. When the air tank pressure equals a preset alarm pressure, an electrical circuit is completed which activates the alarms. The diver can then turn off the alarms by resetting the alarm indicator to a lower pressure setting and continue the dive at a shallower depth.
