Additel ADT 760S is an automatic handheld pressure calibrator designed for precise mobile pressure calibration with integrated pressure generation and automatic control. The series was developed as a simplified version of the new ADT 760A and incorporates its essential pressure functions while omitting the PC-like functionality of the A version. Additel describes the ADT 760S as the Non-PC Version, making it particularly suitable for users who require a robust, straightforward and intuitive solution for automated pressure calibration.

The Additel ADT 760S combines an integrated electrical pump, pressure controller and interchangeable internal pressure module in a portable instrument. The required pressure setpoint is entered directly on the device, after which the calibrator automatically generates and controls the pressure. In many applications, this eliminates the need for separate hand pumps and external pressure regulators.

This makes the ADT 760S ideal for calibrating pressure transmitters, pressure gauges, pressure sensors and pressure switches in calibration laboratories, quality assurance, maintenance and mobile field applications.

The series is available in three basic configurations. The ADT 760S LLP is designed for low and differential pressures up to ±75 mbar. The ADT 760S D covers pressures from −0.86 to 2.5 bar, while the ADT 760S MA extends the operating range from −0.86 to 25 bar, equivalent to approximately −12.5 to 375 psig.

Depending on the internal ADT155 pressure module installed, the Additel ADT 760S provides accuracy down to 0.01 % FS. For the LLP model, accuracy is available down to 0.05 % FS depending on the selected low pressure module. Selecting an internal sensor that closely matches the required pressure range helps optimize measurement performance.

The internal pressure modules are interchangeable, allowing the same ADT 760S platform to be adapted to different internal measurement ranges. External pressure modules are also available for pressure measurement applications. This modular architecture increases flexibility and enables the instrument to cover different calibration requirements.

The current ADT 760S generation also provides a large smartphone-like touchscreen interface. The intuitive user interface simplifies pressure setpoint entry, automatic pressure control and access to the various pressure functions.

An important difference between the ADT 760S and ADT 760A concerns advanced communication and documentation capabilities. According to the manufacturer information provided, data logging and HART functionality are available only with ADT 760A models. There are no DL versions of the ADT 760S. The ADT 760S therefore focuses specifically on automatic pressure generation, control and measurement.

Despite its integrated pump and pressure controller, the series is designed for mobile applications and weighs less than 1.8 kg. Bluetooth, WiFi and USB communication are also available.

For protection of the pneumatic system, the new series supports the CPS – Contamination Prevention System. This helps prevent contamination from connected devices under test from entering the internal pneumatic system, which is particularly useful for field calibration of industrial process equipment.

Ideal for Automated Pressure Calibration

The Additel ADT 760S is designed for users who require automatic pressure generation and control without the advanced documentation or HART functions available with the ADT 760A.

During a typical calibration, the required pressure value is entered directly on the instrument. The integrated electrical pump then generates the pressure and the internal controller automatically adjusts it to the specified setpoint.

This significantly reduces manual effort compared with conventional hand pumps. Particularly during multi-point calibrations, the required setpoints can be approached conveniently and reproducibly.

Typical devices under test include:

• Pressure transmitters
• Pressure sensors
• Digital pressure gauges
• Analog pressure gauges
• Pressure switches
• Differential pressure instruments
• Industrial process pressure instrumentation

The combination of automatic pressure generation and control in a lightweight portable instrument makes the ADT 760S particularly suitable for recurring field and laboratory calibration tasks.

Flexible Modular Design

The Additel ADT 760S uses interchangeable internal ADT155 pressure modules. This allows the pressure range to be adapted to different applications.

Choosing a suitable internal pressure module is particularly important when accuracy specifications are related to full scale. Selecting a pressure range that closely matches the device under test can provide better measurement performance than using an unnecessarily large pressure range.

External pressure modules are also available. These can extend the pressure measurement capabilities of the platform but do not extend the pressure generation capability of the internal pump.

Suitable adapters, hoses and connection solutions are available for different applications. Depending on the configuration, corresponding accessories may already be included with the instrument.

According to the supplied product information, the series is delivered with an ISO/IEC 17025 accredited calibration with measurement data.

Additel ADT 760S LLP

The Additel ADT 760S LLP is the low pressure version of the series and was specifically developed for low gauge and differential pressure applications.

Its maximum range is:

±30 inH₂O or ±75 mbar

Depending on the selected internal ADT155 module, considerably smaller measurement ranges are available. Additel specifies internal ranges down to:

±0.25 inH₂O or approximately ±0.62 mbar

The LLP version is particularly suitable for differential pressure transmitters, filter monitoring, HVAC applications and other low pressure measurement tasks.

Additel ADT 760S D

The Additel ADT 760S D covers the low to medium pressure range.

Its operating range is:

−12.5 to 35 psi or approximately −0.86 to 2.5 bar

The instrument supports both gauge and differential pressure applications, making it suitable for many common industrial pressure measurement and calibration tasks.

Depending on the internal pressure module installed, accuracy down to 0.01 % FS is available.

Additel ADT 760S MA

The Additel ADT 760S MA provides the highest pressure range within the ADT 760S series.

Its pressure range is:

−12.5 to 375 psig or approximately −0.86 to 25 bar

The ADT 760S MA includes an integrated barometric reference and can switch between gauge and absolute pressure.

This makes the MA configuration particularly suitable for pneumatic pressure transmitters, pressure gauges and pressure sensors requiring calibration at pressures up to 25 bar.

No DL Versions for the ADT 760S

Unlike the ADT 760A, there are no LLP-DL, D-DL or MA-DL versions of the Additel ADT 760S.

Technical Specifications

Automatic Pressure Generation and Control

The most important feature of the Additel ADT 760S is its automatic pressure generation capability.

The operator enters the required pressure setpoint. The instrument then performs the remaining process automatically.

The integrated pump generates the pressure and the controller automatically adjusts the system to the required value.

This makes recurring measurement points considerably easier to process and reduces the manual effort normally associated with pressure generation using a hand pump.

Interchangeable Internal Pressure Modules

The Additel ADT 760S can be equipped with different internal ADT155 pressure modules.

This enables the instrument to be adapted more effectively to different devices under test and pressure ranges.

Particularly where accuracy is specified as a percentage of full scale, selecting the smallest appropriate pressure range can provide a metrological advantage.

This modular approach also makes it possible to adapt the instrument to changing calibration requirements without replacing the complete calibrator.

Smartphone-like Operation

The new generation features a large capacitive touchscreen.

Its user interface is inspired by modern smartphones and is designed to provide intuitive operation.

This simplifies pressure setpoint adjustment and navigation through the available pressure functions, helping users perform recurring calibration tasks efficiently.

Contamination Prevention System

The new ADT 760A and ADT 760S generation supports the CPS Contamination Prevention System.

The system helps prevent liquids or contaminants from connected devices under test from entering the internal pneumatic system.

This is particularly important during field calibration of process instruments that have already been used in industrial applications.

Protecting the pneumatic system can help maintain reliable operation and reduce the risk of contamination-related problems.

Communication Interfaces

The Additel ADT 760S supports:

• Bluetooth
• WiFi
