Typical applications include:

• Calibration laboratories
• DAkkS accredited calibration laboratories
• In-house calibration laboratories
• Quality assurance
• Manufacturing and production testing
• Maintenance
• Process industries

• Test benches
• Automated calibration systems

The Additel ADT 762W supports automated testing of pressure transmitters, pressure switches, analog and digital pressure gauges and pressure sensors.

Integrated electrical functions also enable electrical signals to be measured and sourced. Numerous devices under test can therefore be calibrated without requiring separate electrical measurement equipment.

HART and PROFIBUS PA support extends the application range to intelligent field devices. Calibration tasks can be managed directly on the instrument, while measurement results can be recorded and documented for further processing.

Flexible Dual-Range System

A major advantage of the Additel ADT 762W is its integrated dual-range concept.

The GP10K configuration provides internal ranges up to:

The GP15K configuration provides internal ranges up to:

• 6,000 psi
• 15,000 psi / approximately 1,035 bar

Range selection can be performed automatically or manually.

This allows the instrument to operate across different pressure ranges while using the appropriate internal measurement range for the current calibration point.

Depending on the configuration, accuracy down to 0.01 % FS is available, with an alternative accuracy class of 0.02 % FS.

External pressure modules can also be used. The system supports external modules from the Additel ADT 161 series, enabling the calibration platform to be expanded for additional pressure measurement tasks.

Modern Connectivity

The Additel ADT 762W provides extensive communication options for integration into modern calibration environments.

Available interfaces include:

• WiFi
• LAN
• Bluetooth
• USB
• Ethernet

These interfaces facilitate device communication and data transfer and support integration into existing calibration and documentation workflows.

Data logging and integrated task management further support the digitalization and automation of recurring calibration processes.

Technical Specifications

Automatic Hydraulic Pressure Generation

The central feature of the Additel ADT 762W is its automatic hydraulic pressure generation and control.

With conventional high-pressure calibration equipment, the required pressure often has to be generated manually using a hydraulic hand pump and then carefully adjusted to the desired test point.

The ADT 762W automates essential parts of this process.

The system generates and controls defined pressure points automatically, reducing operator workload and supporting reproducible test conditions.

This is particularly beneficial for extensive multi-point calibration sequences and recurring calibration procedures.

Electrical Measurement and Source Functions

In addition to pressure generation and measurement, the Additel ADT 762W provides comprehensive electrical functions.

Current and voltage signals can be measured or sourced directly by the instrument.

Current measurement is available up to ±50 mA, while voltage measurement extends up to ±30 V.

Integrated 24 V loop power supports direct calibration of suitable pressure transmitters.

Pressure switches can also be tested directly, reducing the requirement for additional external measurement equipment.

HART and PROFIBUS PA

The ADT 762W supports both HART and PROFIBUS PA communication.

This allows compatible intelligent field devices to be incorporated into calibration workflows.

Pressure generation, electrical signal measurement and field communication can therefore be combined within one calibration platform.

This is particularly useful for modern process industries where intelligent pressure transmitters require both metrological verification and digital communication.

Data Logging and Task Management

Integrated data logging and task management support structured calibration processes.

Recurring calibration tasks can be prepared, executed and documented directly with the instrument.

Measurement results can be recorded for further evaluation and documentation.

This helps reduce manual documentation effort and supports standardized calibration workflows in calibration laboratories, production and maintenance environments.

Integrated Fluid Management

Unlike conventional oil-operated hydraulic pressure calibrators, the Additel ADT 762W uses deionized water as its pressure medium.

The integrated reservoir has a maximum capacity of 350 ml and incorporates a filter.

This makes the instrument particularly interesting for high-pressure calibration applications where oil contamination of the device under test must be avoided.

The integrated fluid management system supports efficient operation during recurring hydraulic calibration tasks.

Why Choose the Additel ADT 762W?

The Additel ADT 762W combines powerful hydraulic pressure generation with automatic pressure control and precise reference measurement.

Instead of manually generating and fine-adjusting the required test pressure using a hydraulic hand pump, the system automates essential parts of the calibration process.

This provides a major advantage during extensive calibration sequences. Recurring procedures can be standardized while reducing operator workload.

The GP10K configuration enables automatic calibration up to 700 bar, while the GP15K configuration extends the maximum pressure to 1,035 bar.

The integrated dual-range system provides automatic or manual selection between two internal pressure ranges.

For the GP10K configuration, these ranges extend to 3,000 psi and 10,000 psi. For the GP15K configuration, the internal ranges extend to 6,000 psi and 15,000 psi.

The combination with external pressure modules provides additional flexibility.

Extensive electrical functionality is also available. Current and voltage can be measured or sourced, while integrated 24 V loop power supports pressure transmitter calibration.

HART and PROFIBUS PA capabilities provide communication with intelligent field devices.

Integrated task management and data logging further support structured and documented calibration processes.

The Additel ADT 762W is therefore suitable both as a powerful calibration laboratory solution and for demanding mobile service applications.

Typical Calibration Applications with the Additel ADT 762W

The Additel ADT 762W is suitable for numerous applications in industrial pressure metrology.

A key application is calibration of analog and digital pressure gauges. Automatic pressure generation allows defined calibration points to be approached and maintained, simplifying both individual tests and extensive calibration sequences.

For pressure transmitters, both the applied pressure and electrical output signal can be measured using the same system. Integrated 24 V loop power reduces the requirement for additional measurement equipment.

HART and PROFIBUS PA devices can also be incorporated into the calibration process.

Additional applications include testing pressure switches and pressure sensors as well as recurring measuring equipment monitoring in production facilities and calibration laboratories.

The combination of automatic pressure generation, precision measurement and integrated documentation helps simplify complex calibration workflows.

Using deionized water as the working medium is particularly useful for hydraulic high-pressure applications where oil contamination must be avoided.

With two pressure configurations, high accuracy, automatic control and extensive electrical functionality, the Additel ADT 762W provides a versatile solution for professional high-pressure calibration.

Additel ADT 762 or ADT 762W?

One of the most important factors when selecting between the Additel ADT 762 and ADT 762W is the pressure medium.

The Additel ADT 762 uses oil as the hydraulic pressure medium and is suitable for numerous conventional high-pressure calibration applications in laboratories, industry and field service.

The Additel ADT 762W uses deionized water as its pressure medium.

This makes the ADT 762W particularly suitable for devices under test and applications where oil contamination must be prevented.

Both instruments provide automatic hydraulic pressure generation and control and are designed for demanding high-pressure calibration applications.

The choice between the ADT 762 and ADT 762W should therefore take into account the required pressure range, accuracy and, importantly, the pressure medium permitted for the device under test.
