Additel Corporation introduces their new ADT780 series benchtop pressure controllers with precision accuracy to 0.005% of reading + 0.005% FS. The ADT780 configurations have the unique capability of generating pressure to 3,000 psi (200 bar) without the aid of a gas supply. By utilizing an electric pump this unit produces pressures to 1,000 psi (70 bar) and with an electric pump and gas booster to 3,000 psi (200 bar).
Each unit comes with one Intelligent Pressure Module configured to the many range offerings provided. Standard accuracy sensors are certified with a 1 year accuracy of 0.02% FS. The precision quartz-based sensors improve the 1 year accuracy specification to 0.005% of reading + 0.005% FS. Each unit contains process calibrator functionality with HART® and Profibus PA communication capabilities.
The Additel 780 series offers two base ranges: to 1,000 psi (70 bar) and to 3,000 psi (200 bar). The base range establishes the maximum controlling range of the controller. Each configuration includes a control sensor in which is preselected to the range best suited for the application need. External and internal sensors can be used which allows for expanded range and accuracy capability in the future.
