The Additel 793 pressure controller combines the latest control/measure technology, modular design and easy-to-use / maintain features into a single user-friendly device. The Additel 793 provides pressure control up to 15,000 psi (1,000 Bar). For users who require automated production, testing, and calibration, Additel has the workload covered with this pressure controller. The ADT793 accepts one ADT151 dual-range pressure module in addition to a barometric pressure module. This allows users to quickly cover a wide range of pressures.

Additel's built-in 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 five different pressure ranges for the ADT793 controller. Select between 1000 bar (15000 psi), 700 bar (10000 psi), 400 bar (6000 psi), 350 bar (5000 psi) or 200 bar (3000 psi) with a variety of accuracies to meet application requirements.

Additel’s 151 pressure modules have been designed with flexibility and efficiency in mind and can easily be swapped out as needed to meet changing needs and workloads. Higher-pressure ADT151 modules cover two separate pressure ranges and come with individual calibrations for each range. This allows for each module to accurately cover a wide range or pressure workloads. Also, each ADT151 is available in (3) different accuracy levels (0.02% FS, 0.01% FS and 0.01% of reading to meet the demanding needs of our customers. modular configuration provides users with the greatest flexibility.

In the process of efficient and fast-paced production line testing, verification and calibration, users have strict requirements on the speed of pressure controllers. ADT793 adopts professional control technology to effectively improve control rate and stability: control response time (typical) ≤30 seconds, control stability (typical) ≤±(0.003~0.005)%FS, see specifications for more details.

The ADT793 has been designed to support a method of contamination prevention in which the controller only draws in clean fluid during each pressure cycle and purges potentially polluted fluid externally during each cycle to prevent cross-contamination between the controller and units under test (UUT’s).

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 ADT793 to help reduce these concerns and improve durability and dependability when calibrating customers 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.
