Additel’s 151 pressure modules have been designed with flexibility and efficiency in mind and can easily be swapped out as needed to meet changing needs and workloads. Higher pressure ADT151 modules cover two separate pressure ranges and come with individual calibrations for each range. This allows for each module to accuracy cover a wide range or pressure workloads. Also, each ADT151 is available in (3) different accuracy levels (0.02% FS, 0.01% FS and 0.01% of reading) to meet the demanding needs of our customers. Additel’s 151 pressure modules provide users with the flexibility and dependability end users have come to expect.

PRESSURE RANGE
The following tables mainly describes the range, accuracy, and precision of the ADT151 pressure modules. For pressure modules of gauge pressure (GP) and differential pressure (DP) and compound pressure (CP), the zero drift can be eliminated by regular zeroing of the device.The specifications are valid at ambient temperatures from 15°C~35°C. We recommend that these pressure models be calibration annually. ADT151 module provides single-range and dual-range, users can choose according to needs.

Precision: The error components include linearity, hysteresis, repeatability, resolution and temperature compensation.
Accuracy: The error components include linearity, hysteresis, repeatability, resolution, reference standard measurement uncertainty, annual drift, temperature compensation, K=2.
