The Additel 793 pressure controller combines the latest control/measure technology, modular design and easy to use/maintenance features into a single users friendly device. The Additel 793 provides pressure control up to 15,000 psi (1,000 Bar). For users who require automated production, test, 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 user to quickly cover a wide range of pressures.

A Singular Pressure Module Design with a Wide Range of Capabilities
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 of 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.

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 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 the variety of accuracies to meet application requirements.

20% Pressure Step within 30 Seconds
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.

External Reservoir Support
High volume high pressure calibration work can quickly consume working media which can increase hands-on time and can be a hassle for laboratory personnel. The ADT793 supports switching between internal and external liquid storage tanks, allowing users to quickly connect the large capacity external liquid reservoir saving time and labor.

Contamination Prevention System (CPS) Prolongs the Maintenance Interval of the Controller
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 contamination prevention system and integration firmware allows for purges between pressure cycles to further reduce the possibility of introducing contaminates into the system.

Load Volumn Expander Expands the Loading Volume to 250ml
ADT793 supports reciprocating pressurization through a load volume expander to expand the loading volume to 250ml, which can meet the needs of production line users to test multiple UUTs at the same time.
