3 inch Counter Drum Pointer Altimeter - Model LUN 1120

Pressure-sensitive altimeters (ALT) are aircraft instruments indicating the flight altitude or height on the basic of measuring barometric pressure, changing with the altitude. The counter-pointer display is actuated by high stability beryllium capsule. A built-in vibrator minimizes friction and optimizes accuracy. The instrument is intended for measuring and indicating altitude or height between –1,000 and 65,000 ft according to the model. In accordance with the intended use and model the altimeter is also supplied with an encoder with an ICAO output and serial output compatible with main GPS and autopilot suppliers. Electrical output of the barometric scale is also available.  Altimeter is offered to comply with customer’s specification and is mounted for easy servicing. .

3 inch Altimeter - Model LUN 1128

Pressure – sensitive altimeters (ALT) are for use on aircraft to indicate the height above a reference point, generally meaning sea level, assuming standard conditions of temperature and pressure. The altimeters measure the existing barometric pressure. Since atmospheric pressure varies with altitude, this pressure is indicated on the dial in feet of altitude. The altimeters may be manually adjusted to variances in barometric pressure. Temperature is compensated for by a bimetallic element. Altimeter is offered to comply with customer’s specifications (see model designation) and is mounted for easy servicing.

Cabin Altimeter - Model LUN 1130

The cabin altimeter with internal lighting and a differential pressure indicator is intended to measure simultaneously both the pressure altitude and the differential pressure in a pressurised cabin of an aeroplane in relation to the ambient environment. The altitude range is between 0 and 50,000 ft and the differential pressure range is between -1.6 and +5.6 psi.
