Edwards Enables: Metallurgy

The highest purity steels are made by removing hydrogen from molten metal under vacuum. Combine this with vacuum impregnation or coating and you have the building blocks for anything from Aeroplanes to Xylophones

ADC Active Digital Controllers

The Edwards Active Digital Controller (ADC) is a compact single gauge controller and display. It features a bright LED display and simple push-button controls. The ADC automatically recognizes compatible Edwards gauges, loads the appropriate look-up table and displays the pressure in commonly used vacuum units.

The ADC is available in standard and enhanced versions. The standard controller displays the pressure measured by a single active gauge. The enhanced controller supports two similar gauges, is equipped with two variable hysteresis set-points which are linked to 48V dc 1A changeover relays, and two 0-10V dc analog outputs. An RS232 interface is also available on the enhanced version.
