The Additel ADT 783 Pressure Controller is ideal for users requiring automated production, testing, and calibration. The ADT 783 can quickly be outfitted with two controlling ADT151 modules and one reference barometric module to cover a wide pressure range. For all selectable base units, select between one or two ADT151 pressure control modules. An optional barometric module can be added that allows for gauge and absolute measurements. Each module comes with a dual-range calibration, expanding measurement accuracy within each module.

The ADT783-1K is designed for gauge pressure calibration from -14.35 up to 1,000 psi. At least one ADT151 pressure module within the range of CP50 to CP1K must be installed in the high side module bay.

The ADT783-3.6K is designed for gauge pressure calibration from -14.35 up to 3,600 psi. At least one ADT151 pressure module within the range of CP2K to CP3.6K must be installed in the high side module bay.

The ADT783-D is designed for differential and gauge pressure calibration to as low as ±10 inH2O up to 36 psi. At least one ADT151 pressure module within the range of DP30 to DP1K must be installed in the high side module bay.

On all models, the low module bay can be left empty, but when a low-pressure module is installed, the range must be lower than the installed high-pressure module.
