We offer this modular design for faster delivery of a custom system built from a standard fuel rail leak detection platform. The Pascal is offered as a single or dual chamber configuration and for a variety of pressures. Vacuum Instruments Corporation offers advanced leak detection solutions that are accurate, robust and cost-effective along with providing the industry’s fastest delivery times.
Sensitivity: Smallest detectable helium leak rate 5x10-5 Atm-cc/second helium (atmospheric sniffer mode). Helium leak tested to 1.0 × 10-6 atm-cc/sec@600 psig.
Response Time: Approximately 0.5 seconds.
Leak Rate Range: 10-3~10-5 Atm-cc/second direct reading of helium leak rate (compensated for atmospheric sampling).
Startup Time: Less than 3 minutes; one-button automatic operation.
Recovery Time from Helium Contamination: Less than1 minute
Calibrated Leak: 150cc high pressure cylinder with low volume stainless steel leak element traceable to N.I.S.T. with calibration certificate supplied; easily removable for recalibration.
Pressure Measurement: Probe blocked sensor (10-3 Torr); turbopump speed characteristics for high vacuum (10-6 Torr).
Performance (Charging Unit)
Charging Pressure: unit performs evacuation (25" Hg), vacuum decay test and tracer gas backfill to 300 psig. Charging to Lower vacuum levels or 750 psig available as an option.
Testing Options: vacuum decay test and tracer gas, proof test with pressure decay.
Operator Interface: Menu-driven 6” LCD display. Includes automatic or manual sequencing of valves, diagnostics, password security protection and full user programmable test parameters, audio alarm provided for end of cycle, and test completion.
Mass Spectrometer: Miniaturized 90○ deflection, fixed magnet design, all stainless-steel construction, utilizes two long life non-burnout coated filaments.
