Pressure Controllers

The DMA MMA6 is an automatic dual pressure controller for calibrating aircraft instruments. Two high precision resonant transducers are used as reference sensors to control the pressures needed for testing altimeters, vertical speed indicators, anemometers, mach meters, manometers, pressure indicators and calibrators, etc.
The same pressures are applied to the liquid column master manometer to check the accuracy of the measuring system.
All the procedures are computer driven via a standard keyboard and are displayed on a 15" standard CRT.
A dc electric motor driven by the photo scanner, commands the precision ball screw to measure the liquid column height. Temperatures. liquid column vacuum reference and ball screw correction chart are automatically software calculated.
