These modular pressure controllers combine cutting-edge control/measurement technology, modular design, and user-friendly features. The Additel 773 controller series is optimized for low-pressure work by utilizing Additel’s proven low-pressure pump technology in combination with control capabilities that revolutionized the industry as seen in the well-known handheld model ADT760. For users who require automated production, testing, and calibration, Additel has the workload covered with these pressure controllers. The ADT773 can be quickly outfitted with two controlling modules and one reference barometric module to cover a wide pressure range.

Additel's 151 pressure control modules can be installed or replaced within 30 seconds or less. Simply open the upper edge of the cabin to open. As the door opens, the controller will automatically release pressure, providing the safe removal and installation of the ADT151 modules. Additel offers various different pressure ranges for the ADT773 controller utilizing these easy-to-swap pressure modules.

In the process of efficient and fast-paced end-of-line testing and verification and calibration, companies have strict requirements on the speed of pressure controllers. ADT773 adopts professional control technology to effectively improve control speed and control stability.

he Additel 773 comes with an integrated internal low-pressure pump which provides users with a turnkey solution for pressure calibration work. Additel pump designs are well-known and dependable. Not only are they fast, but they also offer the best control and stability in their class. In fact, the automated pumps in other Additel models have revolutionized the industry.

The ADT773 Controller provides valve control for up to 3 external valves. One of the channels is designated for us to control 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.

Calibration of DUT’s (devices under test) often introduces contaminates to a calibration system. Contaminates can cause restrictions in valves, lines, and filters. Additel has included a turn-key solution with the ADT773 to help reduce these concerns and improve durability and dependability when calibrating customer’s devices. The use of an automatic fluid exhaust system and integration firmware allows for purges between pressure cycles to further reduce the possibility of introducing contaminates into the system.
