The Additel ADT 760S-D automatically generates and controls pressure over a range of:
-0.86 to +2.5 bar
corresponding to:
-86 to +250 kPa
or:
-12.5 to +35 psi
The negative pressure capability allows the instrument to generate vacuum relative to atmospheric pressure.
Positive pneumatic pressure can be automatically generated up to:
2.5 bar / 250 kPa / 35 psi
This bidirectional capability makes the ADT 760S-D suitable for a wide variety of gauge and differential pressure calibration applications.
Fully Automatic Pressure Control
One of the main advantages of the Additel ADT 760S-D is the integrated electric pressure pump and automatic controller.
With a conventional calibration setup, the technician may require:
- Manual pressure pump
- Reference pressure instrument
- Fine adjustment valve
- Pressure tubing
- Adapters
The ADT 760S-D combines pressure generation, pressure measurement and pressure control in one portable device.
The operator enters the required pressure setpoint and the calibrator automatically generates and regulates the requested pressure.
This eliminates repetitive manual pumping and fine pressure adjustment during multipoint calibration procedures.
Gauge and Differential Pressure
The Additel ADT 760S-D supports:
Gauge pressure
and:
Differential pressure
Gauge pressure is measured relative to atmospheric pressure.
Differential pressure represents the difference between two pressure points.
This combination makes the D version particularly suitable for process and industrial pressure calibration applications.
Typical applications include:
- Differential pressure transmitters
- Gauge pressure transmitters
- Pressure sensors
- Digital pressure gauges
- Differential pressure gauges
- Low-pressure process instrumentation
- Filter monitoring systems
- Flow-related differential pressure measurement
Pressure Accuracy Down to 0.01 % FS
The ADT 760S-D uses interchangeable internal:
Additel ADT155 pressure modules
Depending on the selected module, pressure accuracy is available down to:
0.01 % FS
FS refers to the full span of the installed pressure module.
The availability of different pressure ranges allows the module to be selected according to the actual calibration requirement.
This is particularly important because using a lower-range module can provide better absolute measurement performance when the required calibration pressures are substantially below the maximum 2.5 bar capability.
Pressure Control Stability
The specified pressure control stability is:
0.005 % FS
The stability specification is referenced to the full scale of the installed internal pressure module.
Stable pressure control is especially important during automated calibration because the pressure should reach a stable condition before the indication of the device under test is evaluated.
The combination of an integrated pump and closed-loop controller allows the ADT 760S-D to automatically approach and maintain the required pressure setpoint.
Interchangeable ADT155 Pressure Modules
The Additel ADT 760S-D uses interchangeable internal ADT155 pressure modules.
The maximum pressure configuration provides pressure up to:
35 psi / 2.5 bar
Lower-range configurations are available for applications requiring improved performance at lower pressures.
Additel offers configurations extending down to approximately:
±10 inH₂O differential pressure
The interchangeable sensor concept allows the pressure measurement range to be adapted to different calibration requirements without replacing the complete calibrator.
Six-Digit Pressure Resolution
The ADT760A/760S platform provides:
6-digit pressure resolution
A wide selection of engineering units is available, including commonly used units such as:
- Pa
- hPa
- kPa
- MPa
- bar
- mbar
- psi
- inHg
- inH₂O
- mmH₂O
- cmH₂O
- mmHg
- torr
- kgf/cm²
This allows the ADT 760S-D to be used conveniently in different industries and international calibration environments.
External Pressure Module Support
In addition to the interchangeable internal pressure module, the ADT 760S-D supports:
two external pressure measurement channels
Compatible Additel external pressure modules can therefore be connected for measurement purposes.
This expands the pressure measurement capability beyond the installed internal pressure range.
The external channels are measurement channels and do not extend the pressure generation capability of the internal pump.
ADT 760S-D – Simplified Pressure-Focused Design
The most important distinction between the ADT 760S-D and the ADT 760A-D is the functional concept.
The ADT 760A is designed as a comprehensive pressure and process calibrator.
The ADT 760S is designed primarily as an:
automatic pressure source and pressure calibrator
The ADT 760S therefore does not include the integrated electrical ports and device communication functions provided by the ADT 760A.
This simplified architecture is ideal when the primary task is:
- Generate pressure automatically
- Control pressure precisely
- Measure reference pressure
- Supply stable pressure to a device under test
For users who already have a precision multimeter or separate process calibrator, the ADT 760S-D can therefore be a highly practical solution.
Ideal for Use with External Electrical Measurement Equipment
When calibrating a 4–20 mA pressure transmitter, the ADT 760S-D can provide the required pressure stimulus.
The electrical transmitter output can then be measured using a separate:
- Digital multimeter
- Process calibrator
- Data acquisition system
- Calibration system
This modular approach can be particularly useful in calibration laboratories that already have high-accuracy electrical reference equipment.
No Integrated Electrical Calibration Channel
Unlike the ADT 760A-D, the ADT 760S-D does not provide the integrated electrical measurement and source channel.
Functions associated with the 760A process calibrator architecture, such as integrated mA measurement and electrical sourcing, should therefore not be specified as standard ADT 760S-D functions.
This distinction is important when selecting between the two instruments.
If combined pressure and electrical process calibration is required in a single handheld device, the ADT 760A-D is the appropriate configuration.
If automatic pressure generation and precision pressure control are the primary requirements, the ADT 760S-D provides the streamlined solution.
Modern Touchscreen Operation
The upgraded ADT760A/760S generation features a modern capacitive touchscreen interface.
Pressure setpoints and instrument functions can be configured directly from the display.
Instead of manually adjusting pressure with a hand pump and fine adjustment valve, the operator can enter the desired setpoint and allow the automatic pressure controller to perform the pressure generation.
This makes repetitive calibration sequences faster and easier to perform.
Bluetooth, Wi-Fi and USB
The Additel ADT 760S-D supports modern communication interfaces including:
Bluetooth
Wi-Fi
and:
USB
These interfaces provide connectivity for instrument operation, software integration and applicable digital workflows.
The ADT760S should nevertheless be distinguished from the documenting process calibrator functions of the ADT760A.
Data Logging – Important Difference
The ADT760S is a simplified non-process-calibrator version.
Additel specifically states that:
data logging capability is only available on ADT760A models
Data logging should therefore not be listed as a standard feature of the ADT 760S-D.
Customers requiring advanced data logging, process documentation or integrated electrical calibration functions should consider the corresponding ADT760A configuration.
HART – Important Difference
The ADT760A platform offers configurations with advanced HART functionality.
The ADT 760S-D, however, is designed as the simplified pressure-focused version without the integrated device communication functionality of the ADT760A.
For applications involving configuration or communication with smart HART transmitters, an appropriate ADT760A configuration should therefore be selected.
Optional Contamination Prevention System
Additel offers a:
Contamination Prevention System (CPS)
for the new ADT760A/760S platform.
The CPS is designed to help protect the internal pneumatic components against contamination introduced through connected devices and pressure lines.
This is particularly useful when instruments from industrial processes are calibrated and their internal cleanliness cannot be guaranteed.
Contaminants can include:
- Oil
- Moisture
- Dirt
- Process residues
- Particles
Protecting the internal pump, pressure module and control components can help maintain reliable long-term operation.
Compact Handheld Design
The ADT760A/760S platform weighs less than:
4 lb / 1.8 kg
This makes the ADT 760S-D suitable for both laboratory and mobile field calibration.
The integrated electric pump eliminates the need to carry a separate manual pressure pump for many calibration tasks.
The combination of portability and automatic pressure control is particularly valuable for technicians who perform multiple calibrations at different locations.
Typical Calibration Applications
The Additel ADT 760S-D Automatic Pressure Calibrator can be used as a pressure source and reference for applications involving:
- Differential pressure transmitters
- Gauge pressure transmitters
- Pressure sensors
- Pressure transducers
- Digital pressure gauges
- Differential pressure gauges
- Low-pressure instruments
- Pneumatic process instrumentation
- Filter monitoring systems
- Flow-related differential pressure instruments
Typical users include:
- Professional calibration laboratories
