Abstract
The device provided for monitoring air pressure in the command sphere of the SDL-1 Submersible is a barometer calibrated in inches of mercury and has a range of only 2.0 psig around a circular dial. No visual or audible alarms are associated with it. A slow leak from any of the high pressure systems used in the operation of the submersible could go undetected by human senses and the pointer on the barometer dial could wind around several times. The device is now considered unsatisfactory as the primary air pressure indicator. A new air pressure alarm system has been developed to augment the barometer. The new system employs an accurate pressure sensor, provides digital readout of the air pressure in psia and activates visual and audible alarms when the air pressure exceeds prescribed bounds around the atmospheric value.
