Founded in 1982, Laversab began as a key supplier to governments worldwide for high accuracy, pressure calibration instrumentation. As an audi...
The very high accuracy of the tester and NIST-traceable calibration make the tester fully RVSM-compliant.
Calibration period: 1 year
Simply enter the target set-points for altitude and airspeed and the unit automatically achieves the targets, ramping at the programmed rates. Control at the set-point is stable within ± 1 foot, ± 0.1 knot or ± 0.0002 inHg
User-programmable limits for altitude, airspeed, Mach and VSI provide protection to the aircraft.
“Jog” and “Hold” features
Set-points can be “jogged” up or down in small increments. Ramping to a set-point can be put on “hold” and controlled at the current measured value.
Brings Pitot and Static outputs to ambient “ground” pressure after completing a test.
A profile of set-points can be downloaded from a PC, allowing the user to step through the set-points using a single key. Each profile can have up to 50 set-points and 20 profiles can be stored in the unit.
Pitot and Static leak-checks can be performed either independently or simultaneously. Three leak-timers can be programmed to perform timed leaks between 1 to 20 minutes. The display of “instant” leak rates provides immediate feedback to the user.
Pressure & Vacuum requirement
External pressure (Dry Air only) and vacuum supplies are required. The PVS is ideally suited for providing these supplies.
Local display and keypad
The local display and keypad are the operator interface for the tester. All valid parameters, including altitude, climb and airspeed, are clearly displayed simultaneously on a single screen on the local display.
