Pressure Specifications
Electrical Specifications (ADT760A)
ADT760A/760S-LLP
The 760A/760S-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 760A/760S-LLP is to ±30 inH2O (±75 mbar) and provides an accuracy
to 0.05%FS (see ordering information for congurations with the option of the 760A/760S 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.
ADT760A/760S-D
The760A/760S-D gives you differential and gauge pressure but at a higher pressure range than the 760A/760S-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 760A/760S-D is an ideal solution to cover very
common gauge and differential pressure measurements. The Additel 760A/760S-D comes with
an internal module of your choice. The maximum range module compatible with the 760A/760S-D
is to 35 psi. Lower pressure congurations down to ±10 inH
2
O differential can be purchased to
improve accuracy at lower pressures.
ADT760A-MA
The 760A
/
760S-MA generates and controls pressure from vacuum pressures up to 375 psig (25
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.

[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.
