Quick Change Pressure Modules (30 seconds)
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 pressure ranges for the ADT773 controller utilising these easy-to-swap pressure modules.
20% Pressure Step within 10 seconds
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.
Air pressure controller: control response time (typical) ≤10S, control stability (typical) ≤±(0.001~0.003)
Built-in pump
The 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 revolutionised the industry.
External Drive Valve Control
The ADT773 Controller provides valve control for up to 3 external valves. One of the channels is designated for us to control the 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.
Contamination Prevention System (CPS) Prolongs the Maintenance of the Controller
Calibration of DUTs (devices under test) often introduces contaminants to a calibration system. Contaminants 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 customers’ devices. The use of an automatic fluid exhaust system and integration of firmware to allow for purges between pressure cycles to further reduce the possibility of introducing contaminants into the system.
