Evaluation of Analytical Industries Inc. Model Number PSR-11-33-NM Oxygen Sensors for Use With the MK 16 MOD 1 Underwater Breathing Apparatus

摘要

The purpose of this study was to conduct unmanned and manned testing to evaluate the effectiveness of the Analytical Industries's; PSR-11 oxygen sensor (alone and in combination with approved Teledyne R-10DN oxygen sensors) with the MK 16 MOD 1 underwater breathing apparatus (UBA) to a maximum excursion depth of 300 feet of seawater (fsw).1 Primarily employed by Navy Explosive Ordnance Disposal (EOD) divers, the Mk 16 MOD 1 UBA is an electronically controlled, closed-circuit, mixed gas, constant oxygen partial pressure (PO2) underwater life-support system that meets military specifications for nonmagnetic and acoustically safe equipment. This system employs three sensors to monitor the oxygen concentration in its breathing loop. Currently only one oxygen sensor, the Teledyne R-10DN, is approved for use with the Mk 16 MOD 1 UBA. Having another sensor approved could mitigate potential operational problems if the current sensor is unavailable or its use is suspended for any reason. The PSR-11 was therefore a candidate for consideration as an approved, compatible substitute for the Teledyne R-10DN sensor.
