Four Test Ports for Pressure Calibration
The primary purpose of the Additel ADT 12X Pressure Manifold is to expand a single pressure calibration connection into:
four test ports
This provides a simple way to connect several pressure instruments to a common pressure source.
For example, a pressure calibration setup can include:
- A pressure source
- A reference pressure instrument
- One or more devices under test
Using a manifold simplifies the pneumatic or hydraulic connection of these components.
This is particularly useful in calibration laboratories where several pressure gauges, transmitters or sensors need to be connected during a calibration procedure.
Additel ADT121 Pneumatic Pressure Manifold
The Additel ADT121 is the pneumatic version of the ADT 12X series.
Its operating pressure range is:
-15 to 3,600 psi
or:
-1 to 250 bar
The ADT121 is designed for pneumatic pressure calibration and can be used with suitable clean gas pressure systems.
An important feature of the ADT121 is its:
built-in filter
The filter helps prevent contamination from connected devices under test from entering the pressure calibration system.
This is particularly valuable when customer instruments of unknown internal cleanliness are connected to sensitive reference equipment or pressure controllers.
Additel ADT123 Hydraulic Pressure Manifold
For substantially higher pressure applications, Additel provides the:
ADT123 Hydraulic Pressure Manifold
The current pressure range extends to:
15,000 psi
or:
1,000 bar
The ADT123 therefore provides a suitable pressure distribution solution for hydraulic calibration systems operating far beyond the pneumatic range of the ADT121.
Typical pressure sources can include:
- Hydraulic pressure pumps
- Hydraulic pressure controllers
- Deadweight testers
- Piston gauges
The high pressure capability makes the ADT123 particularly suitable for professional pressure calibration laboratories working with industrial high-pressure instrumentation.
Pneumatic vs. Hydraulic Versions
The correct ADT 12X manifold should be selected according to the pressure medium and maximum operating pressure.
| Series | Application | Pressure Range |
|---|---|---|
| ADT121 | Pneumatic | -1 to 250 bar |
| ADT123 | Hydraulic | -1 to 1,000 bar |
The ADT121 is the appropriate choice for pneumatic pressure systems.
The ADT123 should be selected for compatible hydraulic pressure applications requiring pressures up to 1,000 bar.
Four Hand-Tight Quick Connectors
Each ADT121 and ADT123 pressure manifold is equipped with:
four hand-tight quick connectors
These connectors are designed to simplify installation and removal of pressure instruments.
Conventional threaded pressure connections often require:
- Open-end wrenches
- Thread-sealing tape
- Additional adapters
- Considerable installation time
The Additel hand-tight connector system is designed to eliminate the need for wrenches and PTFE tape at the quick connection.
This can significantly improve productivity when devices under test are frequently changed.
Ideal for Calibration Laboratories
Pressure calibration laboratories often need to change devices under test several times per day.
A conventional pressure setup may require technicians to repeatedly disassemble and reseal threaded connections.
The Additel ADT 12X Pressure Manifold provides four convenient test ports, making it easier to connect multiple instruments and exchange devices during calibration work.
This can reduce setup time and simplify the overall calibration process.

Integrated Filter for Pneumatic Calibration
The ADT121 incorporates a filter to help protect the pressure calibration system against contamination introduced by devices under test.
This is an important feature when the manifold is connected to precision equipment such as:
- Pressure controllers
- Reference pressure indicators
- Precision pressure modules
- Pneumatic calibration pumps
Contamination can affect valves, sensors and pressure-control components.
The integrated filter therefore provides an additional level of protection for the pneumatic calibration system.
Use with Pressure Controllers
The Additel ADT 12X Pressure Manifold can be combined with automatic pressure controllers.
A typical configuration consists of:
Pressure Controller → ADT 12X Manifold → Devices Under Test
The controller generates and regulates the pressure, while the manifold distributes the pressure to the connected instruments.
This type of setup can be particularly useful when several pressure instruments need to be connected to the same calibration pressure.
Current Additel pressure controller solutions include systems such as the ADT773, ADT783 and ADT793.
Use with the Additel ADT780
The ADT121 manifold has also been used as an external manifold for the Additel ADT780 pressure controller platform.
This provides additional test connections and allows several pressure devices to be connected to the controller.
For laboratories already operating an ADT780 system, the ADT121 can therefore be a useful accessory for expanding the pressure connection setup.
Use with Calibration Pumps
The ADT 12X series can also be used with suitable manual or automatic pressure pumps.
The basic setup is:
Pressure Pump → Pressure Manifold → Reference + Device Under Test
The manifold distributes the generated pressure to the connected pressure instruments.
This allows the same pressure source to be used for the reference instrument and device under test.
Use with Deadweight Testers and Piston Gauges
Additel also specifies the ADT 12X manifolds for use with:
Deadweight testers
and:
Piston gauges
In this configuration, the manifold provides additional test ports downstream of the pressure standard.
This can simplify connection of devices under test and associated pressure measurement equipment.
Digital Pressure Gauge Calibration
A typical digital pressure gauge calibration setup may consist of:
- Pressure source
- Reference pressure gauge
- ADT 12X manifold
- Device under test
The manifold allows the reference and test instruments to experience the same generated pressure within the connected system.
For high-accuracy calibration, differences in pressure caused by height, pressure medium and installation should be considered as part of the measurement uncertainty evaluation.
Pressure Transmitter Calibration
The ADT 12X can also simplify calibration of pressure transmitters.
Several transmitters can be mechanically connected to the manifold while a common pressure is generated.
Depending on the calibration procedure, this can reduce the time required to change pressure connections between devices.
The electrical outputs of the transmitters must, of course, be measured using suitable process calibration or electrical measurement equipment.
Pressure Sensors and Transducers
Industrial pressure sensors and transducers can also be connected to the manifold.
This makes the ADT 12X suitable for:
- Calibration laboratories
- Production test stations
- Quality assurance
- Research and development
- Instrument service
- Pressure measurement test benches
Important Considerations for Precision Calibration
When several instruments are connected to one pressure manifold, the complete pressure system should be considered.
Important influences can include:
- Height differences between reference and device under test
- Pressure medium density
- Temperature
- Trapped gas in hydraulic systems
- Leaks
- Connection volume
- Contamination
- Pressure stability
- Correct pressure fittings
For high-accuracy calibration, pressure head corrections may be required when the reference instrument and device under test are positioned at different vertical reference levels.
Increased Calibration Productivity
The practical advantage of the Additel ADT 12X Pressure Manifold is not only its pressure capability but also its ability to simplify daily calibration work.
Four quick-connect test ports allow technicians to connect and exchange instruments efficiently.
This can reduce the time spent on:
- Thread sealing
- Tightening fittings
- Reconfiguring pressure lines
- Changing adapters
- Connecting additional instruments
The result is a cleaner and more efficient pressure calibration setup.
