Additel ADT 773 Pressure Controller

The Additel ADT 773 Pressure Controller is optimized for low-pressure work, utilizing Additel’s low-pressure pump technology in combination with the control capabilities of the handheld model ADT760. The ADT 773 is ideal for users requiring automated production, testing, and calibration. The ADT 773 can be outfitted with two controlling ADT151 modules and one reference barometric module to cover a wide pressure range. The ADT151 pressure modules can be installed or replaced within 30 seconds or less. As the cabin door opens, the controller will automatically release pressure, providing the safe removal and installation of the ADT151 modules. At least one ADT151 Digital Pressure Module within the range of DP30 to DP400 must be installed in the high-side module bay. The low bay can be left empty, but when a low-pressure module is installed, the range must be lower than the installed high-pressure module. The ADT 773 has an integrated internal low-pressure pump that gives users a turnkey solution for pressure calibration work. The controller provides valve control for up to 3 external valves. One of the channels is designated for controlling a contamination prevention system (CPS), which helps to prevent media contamination. The remaining two channels can be used to control external vacuum pumps or external isolation valves for greater flexibility and compatibility for individual situations.
