These modular pressure controllers combine state-of-the-art control and measurement technology,
modular design and user-friendly features. The Additel 783 controller series is optimized for
high-speed pressure generation without compromising accuracy and stability. For users who need
automated production, testing and calibration, Additel has you covered with these controllers.
The ADT783 can be quickly equipped with two control modules and a reference barometric module
to cover a wide pressure range. The Additel 783 series offers three base units to choose from,
ranging from 3500 psi (250 bar) down to low differential pressure.
ADT783-D
The ADT783-D is designed for the calibration of differential and gauge pressure from ±2 inH2O (±5 mbar) up to 36 psi (2.5 bar). Choose between one or two pressure control modules. Each module features dual-range calibration, which extends measurement accuracy within each module. This unit has a control stability of 0.003%FS. In addition to the two control modules, an optional barometric module can be added to enable gauge and absolute pressure measurements.
ADT783-1K
The ADT783-1K is designed for the calibration of gauge pressure from -14.35 psi (-0.99 bar) up to 1000 psi (70 bar). Choose between one or two pressure control modules. Each module features dual-range calibration, which extends measurement accuracy within each module. This unit has a control stability of 0.003%FS. In addition to the two control modules, an optional barometric module can be added to enable gauge and absolute pressure measurements.
ADT783-3.5K
The ADT783-3.5K is designed for the calibration of gauge pressure from -14.35 psi (-0.99 bar) up to 3500 psi (250 bar). Choose between one or two pressure control modules. Each module features dual-range calibration, which extends measurement accuracy within each module. This unit has a control stability of 0.003%FS. In addition to the two control modules, an optional barometric module can be added to enable gauge and absolute pressure measurements.

Specification for ADT783 pressure modules
The following tables provide information about our ADT151 modular pressure sensors,
which are specifically designed for easy installation in the front bays of the
ADT783 pressure controller. Our specifications for differential pressure modules (DP)
and gauge pressure modules (GP) include accuracy statements for linearity, hysteresis,
repeatability, temperature compensation and annual drift. Both the DP and GP pressure
modules can occasionally be zeroed by the controller to minimize the effect of zero drift.
The specifications apply over a temperature range of 15°C to 35°C. We recommend that
these pressure modules be calibrated annually.
