Electrical Specifications
ADT760-LLP
The 760-LLP is designed for low pressure calibration and comes with a build-in pressure module of your choice. The
maximum range module compatible with the ADT760-LLP is to ±30 inH2O (±75 mbar) and provides an accuracy to
0.05%FS (see ordering information for configurations with the option of the ADT760 and a module of your choice).
Additional internal pressure modules (ADT155 series) are available and provide a variety of ranges down to ±0.25
inH
2
O (±0.62 mbar). The accuracy of 0.05%FS and control stability 0.005%FS is based on the internal module’s span.
Measurements can be made in gauge or differential mode.
ADT760-D
The 760-D gives you differential and gauge pressure but at a higher pressure range than the ADT760-LLP. Covering
the range of -12.5 to 35 psi (-0.86 to 2.5 bar) and with an accuracy of 0.01%FS or 0.02%FS depending on the
interchangeable ADT155 module used, the ADT760-D is an ideal solution to cover very common gauge and differential
pressure measurements. The Additel 760-D comes with an internal module of your choice.
The maximum range module compatible with the ADT760-D is to 35 psi. Lower pressure
configurations down to ±10 inH
2
O differential can be purchased to improve accuracy at lower
pressures.
ADT760-MA
The 760-MA generates and controls pressure from vacuum pressures up to 300 psig (20 bar.g)
with an accuracy of 0.01%FS or 0.02%FS depending on the interchangeable ADT155 module
used
.
Equipped with a built-in barometric reference, each unit can switch between gauge and
absolute pressure types. A variety of internal sensors are available which offer lower pressure
ranges for improved performance.
Documenting Process Functionality
Each model of the Additel 760 series has an option incorporating documentation and communication functions turning
your 760 into a multifunction documenting process calibrator. This feature provides HART communication, task
documentation and data logging.

[1] FS specication applies to the span of the module range.
[2] Stability based on FS of the internal pressure module. Stability is 0.005%FS or 0.05 pa whichever is greater. Internal module is switchable.
[3] Specication based on gauge measurement. An additional 55 pa uncertainty will need to be included when measuring in absolute mode.
[4] 55 Pa uncertainty (k=2) includes calibration uncertainty, linearity, and long-term stability (<30 Pa per year). Barometer range of 60 to 110 kPa.
