Automated Pneumatic Pressure Control up to 250 bar
The Additel ADT 783-3.6K provides automated pneumatic pressure control over a remarkably wide range extending from:
-0.99 to 250 bar
or:
-14.35 to 3,600 psi
This makes the controller suitable for calibrating a wide variety of industrial pressure measuring instruments.
Unlike portable automatic pressure calibrators with an integrated pressure-generation pump, the ADT 783-3.6K is designed as a high-performance laboratory pressure controller using an:
external pneumatic pressure supply
The required pressure medium is clean and dry:
Air or Nitrogen
This architecture enables fast and highly stable automatic pressure control at pressures up to 250 bar.
External Pressure Supply up to 280 bar
The ADT 783-3.6K requires an external gas source for positive pressure generation.
Additel specifies a maximum supply pressure of:
280 bar
For optimum pressure control, the manufacturer recommends setting the source pressure to approximately 110 % of the maximum range of the installed internal pressure control module or 1 bar, whichever is greater.
A suitable high-pressure gas supply and all associated pressure components must be selected according to the required operating pressure.
This is particularly important for a pneumatic calibration system operating at pressures approaching 250 bar.
Gauge Pressure Control
The standard Additel ADT 783-3.6K configuration is designed for:
Gauge Pressure
Gauge pressure is measured relative to atmospheric pressure:
p_gauge = p_absolute – p_atmosphere
The controller covers both negative gauge pressure and positive pressure up to 250 bar.
This provides a very wide operating range for industrial gauge pressure calibration.
Optional Absolute Pressure Capability
The ADT 783-3.6K can optionally support switching between:
Gauge Pressure
and:
Absolute Pressure
when the appropriate atmospheric reference pressure module is installed.
The additional barometric reference provides the atmospheric pressure information required for the gauge-to-absolute pressure conversion.
This option is particularly useful for laboratories that need one automated pressure controller for both gauge and absolute pressure instruments.
Two Interchangeable ADT151 Pressure Module Bays
A major advantage of the Additel ADT 783-3.6K is its modular pressure measurement architecture.
The controller provides:
two interchangeable internal pressure module bays
for Additel ADT151 digital pressure modules.
The high-pressure module bay supports:
CP2K/2KM through CP3.6K/3.6KM
while the low-pressure module bay supports:
CP150/150M through CP3.6K/3.6KM
This provides considerable flexibility when configuring the pressure controller for different calibration workloads.
ADT151 CP3.6K Pressure Module
For applications requiring the full 250 bar capability, the ADT151:
CP3.6K
module provides a compound gauge pressure range of approximately:
-15 to 3,600 psi
or:
-1 to 250 bar
The CP3.6K is specifically listed by Additel as compatible with the ADT 783-3.6K.
Depending on the selected module performance class, the ADT151 architecture provides high-precision reference measurement for professional pressure calibration.
Multi-Range Pressure Calibration
Using two interchangeable internal pressure modules allows the ADT 783-3.6K to cover high pressure while maintaining improved performance at lower pressure ranges.
For example, a laboratory may need to calibrate:
- 10 bar pressure transmitters
- 40 bar digital pressure gauges
- 100 bar pressure sensors
- 160 bar pressure gauges
- 250 bar pressure transducers
Using only a 250 bar reference range for all these applications may not provide the optimum absolute measurement uncertainty at lower pressures.
A suitable lower-range ADT151 module can therefore be installed in the second module bay.
The controller can use:
Fixed
or:
Auto
range selection to select the appropriate measurement range.
Accuracy Options
The measurement performance of the Additel ADT 783-3.6K depends on the selected ADT151 pressure module.
Available accuracy classes include:
0.02 % FS
0.01 % FS
and high-performance configurations reaching:
0.01 % RD
This allows the pressure controller to be configured according to the measurement uncertainty requirements of the application.
Precision vs. Accuracy
Additel distinguishes between:
Precision
and:
Accuracy
for the ADT783 system and its ADT151 pressure modules.
For the ADT 783-3.6K, the available precision specifications include:
0.01 % FS
0.007 % FS
or:
0.008 % RD
depending on the selected module.
Available accuracy specifications include:
0.02 % FS
0.01 % FS
or:
0.01 % RD
Precision includes error contributions such as linearity, hysteresis, repeatability, resolution and temperature compensation.
The accuracy specification additionally considers reference standard measurement uncertainty and annual drift.
This distinction is important when selecting a pressure module for professional calibration applications.
Control Stability <0.003 % FS
The pressure control stability of the Additel ADT 783-3.6K is specified as:
<0.003 % FS
Under suitable operating conditions, typical performance can reach:
0.001 % FS
Additional stabilization time may be necessary when the best 0.001 % FS performance is required.
High pressure stability is particularly important when calibrating high-resolution digital pressure gauges, reference pressure instruments and precision transmitters.
Pressure Control in Less Than 10 Seconds
Despite its pressure capability up to 250 bar, the ADT 783-3.6K provides very fast pressure regulation.
Additel specifies a control response time of:
<10 seconds
under the manufacturer’s defined test conditions.
The test condition uses a 50 ml external load volume and a 20 % pressure step, with the time measured until 0.005 % FS stability is achieved.
Achieving the tighter typical 0.001 % FS stability can require additional stabilization time.
Fast, Standard and Custom Control Modes
The ADT 783-3.6K provides three pressure control modes:
Fast
Standard
Custom
These modes allow the pressure control behavior to be adapted to the connected device and calibration procedure.
This is particularly useful when different test volumes or sensitive devices require different pressure-control characteristics.
Maximum Overshoot <1 % FS
Additel specifies maximum pressure overshoot of:
<1 % FS
Controlled pressure approach helps protect the device under test and reduces unnecessary pressure excursions during automated calibration.
This becomes particularly important at higher pressures where even a relatively small percentage of full scale represents a significant absolute pressure.
External Load Volume up to 1,000 ml
The ADT 783-3.6K supports external load volumes up to:
1,000 ml
This allows the controller to be connected to different pressure instruments, manifolds and calibration setups.
Actual pressure response depends on factors including:
- External volume
- Pressure step
- Supply pressure
- Selected control mode
- Pressure range
- Required stability
1/4 BSP Pressure Connection
The pressure connection of the ADT 783-3.6K is:
1/4 BSP male
All pressure ports incorporate filters in the approximately:
40 to 100 µm
range.
These filters help protect the internal pressure control system against contamination.
Optional Contamination Prevention System
An optional:
Contamination Prevention System (CPS)
is available for the ADT 783-3.6K.
A CPS is particularly useful when devices under test may contain contamination such as:
- Oil
- Moisture
- Particles
- Process residues
Preventing contamination from entering the controller helps protect the internal valves, pressure modules and pneumatic control system.
Digital Pressure Gauge Calibration
The Additel ADT 783-3.6K is particularly well suited for automatic calibration of digital pressure gauges.
A typical calibration sequence can include:
- Zero pressure
- Increasing pressure points
- Full-scale pressure
- Decreasing pressure points
- Return to zero
Automatic pressure control significantly reduces manual adjustment and can improve the consistency of repetitive calibration procedures.
Pressure Transmitter Calibration
The controller can also provide precise reference pressures for pressure transmitter calibration.
Typical devices include:
- Gauge pressure transmitters
- Smart pressure transmitters
- Pressure transducers
- Industrial pressure sensors
- Absolute pressure transmitters with the appropriate reference configuration
The fast response and remote-control capability make the ADT 783-3.6K particularly suitable for automated calibration systems.
Production Pressure Testing
The ADT 783-3.6K is also suitable for repetitive production testing.
Pressure sensors and transmitters can be tested at predefined pressure points as part of an automated test sequence.
The combination of:
- Fast pressure control
- High stability
- Interchangeable reference modules
- Automatic range selection
- Remote communication
makes the controller suitable for production and quality assurance environments.
Remote Operation and Automation
The ADT783 platform is designed for integration into automated calibration systems.
Remote communication enables the controller to be operated by calibration software, laboratory systems and custom test applications.
Additel provides programming commands as well as Modbus commands for the ADT773, ADT783 and ADT793 controller platforms.
This makes the ADT 783-3.6K particularly attractive for automated calibration benches and production test systems.
