Edwards (formerly BOC Edwards) Vacuum Gauges and Vacuum Calibration

Edwards ADC Active Digital Controller

The BOC 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 recognises compatible BOC 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 - it has two variable hysteresis set-points which are linked to 48 V d c. 1 A changeover relays and two 0-10 V d.c. analog outputs. To aid system integration, the enhanced controller is provided with an RS232 interface.

When combined with a suitable gauge, such as the BOC Edwards APGX-H Convection Pirani or Wide Range gauge (WRG), the ADC represents a cost effective means of monitoring and controlling process vacuum in a broad range of applications.
