Pressure Leak Detector
Multi-Zone Pressure Drop Detection for Penetration Verification
The pressure leak detector is a 2 kg instrumentation unit that utilizes capacitive pressure transducers and mass spectrometers to identify structural breaches across partitioned lunar habitat zones. Operating against the vacuum of the lunar environment, where cumulative micrometeoroid impacts pose penetration risks, the system monitors atmospheric decay against a detection threshold of 100 pascals per minute. Upon identifying an anomalous drop, it commands interconnect hatches to isolate the compromised zone within 30 seconds to prevent cascading depressurization. Drawing 5 watts of power, the hardware provides a 200,000-hour mean time between failures across a 25-year operational lifespan.
Multi-zone pressure-drop detection identifying air-tight breaches after impact, triggering rapid isolation of affected zone.
