Founded in 1982, Laversab began as a key supplier to governments worldwide for high accuracy, pressure calibration instrumentation. As an audi...
Automated operation (at an Affordable price)
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 and ± 0.1 knot. The tester's low price makes it very affordable
Calibration period: 1 year
User-programmable limits for altitude, airspeed, Mach, VSI and airspeed-rate provide protection to the aircraft.
An internal differential-pressure relief valve provides protection against negative airspeed.
Internal Battery (Optional)
The internal battery allows for 8 hours of continuous operation. Re-charge time is only 8 hours.
Low-temperature operation (optional)
With optional internal heaters, the unit can be operated down to -40°C
“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. Ambient pressure is constantly monitored.
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 15 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 source
Built-in diaphragm pumps provide the pressure and vacuum source for the unit.
The Remote unit is the operator interface for the tester. It features a sunlight-readable 5.8” color display, a back-lit keypad and a touch-screen (which can be disabled). All operations are performed from a single screen which displays all pertinent parameters.
Manual Vent Valves
On loss of power, the unit maintains pressure (except for leaks). The unit can be manually vented to “Ground” at a controlled rate using precision metering valves.
