These modular pressure controllers combine cutting-edge control/measurement technology, modular design, and user-friendly features. The Additel 783 controller series is optimized for high speed to pressure without compromising accuracy and stability.  For users who require automated production, test, and calibration, Additel has the workload covered with these pressure controllers. The ADT783 can be quickly outfitted with two controlling modules and one reference barometric module to cover a wide pressure range.  The Additel 783 series offers three base units to choose from, which range from 3500 psi (250 bar) down to low pressure differential.

ADT783-D
The ADT783-D is designed for differential and gauge pressure calibration to as low as ±2 inH2O (±5 mbar) up to 36 psi (2.5 bar). Select between one or two pressure control modules. Each module comes with a dual-range calibration, expanding measurement accuracy within each module. This unit has a control stability of 0.003%FS. In addition to the two control modules and optional barometric module can be added which allows for gauge and absolute measurements.

ADT783-1K
The ADT783-1K is designed for gauge pressure calibration from -14.35 (-0.99 bar) up to 1000 psi (70 bar). Select between one or two pressure control modules. Each module comes with a dual-range calibration, expanding measurement accuracy within each module. This unit has a control stability of 0.003%FS. In addition to the two control modules and optional barometric module can be added which allows for gauge and absolute measurements.

ADT783-3.6K/6K
The ADT783-3.6K / 6K is designed for gauge pressure calibration from
-14.35 (-0.99 bar) up to 6000 psi (420 bar). Select between one or two pressure control modules. Each module comes with a dual-range calibration, expanding measurement accuracy within each module. This unit has a control stability of 0.003%FS. In addition to the two control modules and optional barometric module can be added which allows for gauge and absolute measurements.

Quick Change Pressure Modules
Additel's 151 pressure control modules can be installed or replaced within 30 seconds or less. The upper edge of the cabin is simple 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 ADT783 controller by utilizing these easy to swap pressure modules.

Modular Design, Easy Maintenance
The ADT783 adopts a variety of easy maintenance design methods, which can quickly change the pressure control module, quickly change the pressure control component, quickly clean the solenoid valve, and fine filtration of pollution particles.

20% Pressure Step within 10 seconds
In the process of efficient and fast-paced end-of-line testing, verification and calibration, companies have strict requirements on the speed of pressure controllers. ADT783 adopts professional pressure control technology to effectively improve control speed and control stability. Air pressure controller: control response time (typical) ≤10S, control stability ＜ 0.003%FS, see specifications for more details.

Vacuum Pump Automatic Start-Stop, Greatly Extending the Life of the Vacuum Pump
The ADT783 incorporates a built-in positive pressure/vacuum gas source with switching components. When controlling a small pressure above the atmospheric pressure point, it can be controllable and stable without connecting the vacuum pump.  When controlling negative pressure or vacuum pressure, there is no need to utilize an external vacuum pump or protection components. A solid-state relay can be connected to the power supply line of the vacuum pump to realize fully automatic vacuum pump start-stop control, greatly extending the life of the vacuum pump.

Plug-and-Play 9065 Precision Electrical Measurement Module
When controllers are used for pressure transmitter calibration, they often need to be equipped with electrical measurement devices and a 24V power supply. The higher the accuracy level of the transmitter, the higher the level of electrical measurement equipment required to meet a 3:1 or 4:1 uncertainty transfer. This often brings significant complexity and cost to the system for users. The 9065 precision electrical measurement module supports current and voltage measurements (7.5-digit measurement level) and comes with a 24V power supply. It connects to ADT783 controller via USB, offering a plug-and-play solution with the highest cost-effectiveness.
