Automated Hydraulic Pressure Calibrator
Additel 762W
The Additel 762W Automated Pressure Calibrator provides a revolutionary turnkey
solution for automated pressure calibration work up to 10,000 PSI using deionized
water as the working media.
Designed for use in both the eld and the laboratory, the portability and accuracy of this
state-of-the-art product will quickly become the favorite go-to calibrator for lab personnel
and eld technicians alike.
With fully automated support for calibration of pressure transmitters, switches, dial
and digital gauges and sensors, including HART/PROFIBUS devices in conjunction
with a fully integrated task feature, data collection and Wi-Fi connectivity, we had our
customer’s needs in mind when designing our most capable pressure calibrator to date.

Pressure Calibration Equipment
Dual-Range Accuracy to 0.01% FS
The ADT762W includes the unique ability to automatically switch between
different internal calibrations depending on the current control pressure of the
ADT762W. Additel provides calibrations unique to each ADT762W for ranges
of 0-3,000 PSI (200 Bar) and 0-10,000 PSI (700 Bar). As the calibrator is
pressurized, it will automatically select the control and measurement specication
based on the specic pressure range. Pressure calibration range selection can
be set to “auto” mode so the calibration range is automatically selected by the
ADT762W based on the set point pressure, or the calibration range can be
manually selected.
Dual-Mode HART Communication
HART pressure transmitters can be directly maintained and calibrated without any other equipment or tools. The
ADT762W provides an automatic HART calibration mode as well as a manual mode. This dual-mode HART
communication function not only provides an efcient and convenient interoperability mode for DUT, but also supports
access to a fully HART capable calibrator.
Documented Task Feature
The powerful documented calibration task application allows users to quickly
create and execute tasks without the need for a PC or tablet. The ADT762W
automatically analyzes errors, generates test reports, while storing results locally.
The Additel 762W can support up to 1000 documented tasks which can be stored
and recalled at any time to help save time and money.
Built-in Auto-Purge Application
Purging hydraulic calibration systems can be challenging and time consuming.
The ADT762W has been specifically designed for use with water. It comes
standard with a specially designed manifold to help provide a constant positive
pressure environment to mitigate concerns with contamination when using
water as a medium. The integrated auto-purge system saves time, money and
frustration by completely automating the removal of air from the system. With the
push of a button, the ADT762W quickly manages the system purging. This helps
to free up time for technicians to attend to other needs.
Dual-Port Manifold with Automatic Fluid Extraction
When using hydraulic systems, we know that oils are a better lubricant and
sustain the life of seals and components than water. But we recognize that for
some applications, using oil is not an option. The ADT762W is designed to only
be used with deionized water. The ADT762W has a built-in fluid management
system to reduce standing water in the system which eases future maintenance
requirements. The ADT762W should be used with the provided manifold which
has a communication connection directly to the unit to actuate a vent valve built
into the manifold. This configuration is designed to prevent contaminated fluid
from returning to the base unit and manifold as it is deposited into a special waste
tank on the bottom of the ADT107 manifold. This function helps ensure the longest
life of the unit and reduced maintenance costs.
