OVERVIEW

Additel’s new Multi-functional Documenting Process Calibrator series takes portability, functionality, and accuracy to

a whole new level and packages it with an intuitive and easy to use color touchscreen display. This series includes an

advanced documenting pressure calibrator (ADT227) and an advanced documentation process calibrator with a built-

in HART communicator (ADT227-HART). Additionally, each calibrator has an ATEX certified intrinsically safe option

(ADT227Ex) allowing you to perform calibration in the harshest of environments. We’re condent these new tools will not

only meet your calibration requirements but will make metrology simple for you!

Features

Easy-to-use Cellphone Like Interface

Additel's new and improved ADT227 series provides much improved

accuracies including an electrical accuracy of 0.005% RD + 0.005% FS,

high-static differential pressure mode accuracy to 0.002% FS and across

the board improvements in temperature measurement accuracies.

The ADT227 series brings an all new user interface to the world of process

calibrators. With a menu driven interface and a small size/weight, the ADT227

is the industry's smallest advanced multifunctional process calibrator with an

intrinsically safe version to boot (ADT227Ex). It adopts advanced human hand

engineering design for the most convenient eld handheld process calibrator

available.

The ADT227 has been developed with a powerful embedded operating

system which solves common problems of other designs including slow

response, cumbersome key operation, high power consumption and overall

slow processing.

The ADT227 series delivers highly improved thermocouple measurement

capabilities by vastly improving the cold junction compensation(CJC)

specications and a much improved stabilization time.

The demands of remote calibration work can be challenging. The ADT227 series is

lightweight and highly portable and utilizes an advanced color LCD screen to help ensure

you can easily see, even in the (Ex) intrinsically safe versions.

All models in the ADT227 family have been designed with ruggedness and dependability in

mind and meet IP67 standards with a 1-meter drop test, 4G vibration, xenon exposure and

130g steel ball drop testing of the display.

Other environmental conditions have also been considered, such as temperature and

humidity. To combat these external elements, Additel has designed a unique internal circuit

design and process technology to allow for the utmost condence in your critical calibration

and measurement work.

The Additel 227Ex series calibrators have passed the most stringent testing by

certified organizations to acquire intrinsically safe certificates, ATEX, IECEX.

The explosion-proof grade (Ex ia IIC T4 Ga), can be widely used in potentially

explosive environments, such as oil and gas platforms, oil refineries, chemical

and petrochemical plants, pharmaceutical industries, energy and gas processing

industries.

Each intrinsically safe calibrator has an advance transective color LCD display

which has enhanced visibility when viewed in direct sunlight. No matter where

your work takes you, these calibrators are up to the task.

The Additel 227 non-Ex version is equipped with “true effective

value” RMS measuring function, which can measure the RMS

of various waveforms with no need to consider distortion or

waveform parameters and other errors caused by various

waveforms

Additel 227 Series Calibrators come with a powerful documenting calibration task

application which provides a turnkey solution for automation and paperless calibration

management.

Tasks are easily created for temperature, pressure, flow and loop instruments. Up

to 10,000 documented tasks for ADT227 and up to 1,000 documented tasks for

ADT227Ex can be stored in the extensive on-board memory. Many tasks, when

executed, are fully automated in data collection and performance validation, such as

pass/fail and hysteresis calculations. All information can be integrated into Additel’s

ACal software for additional calibration management.

Automated Tasks for Paperless Calibration Management

The built-in full HART communicator will work with most HART transmitters . The

ADT227-HART contains an extensive DD library to meet the needs of your smart

transmitter. Our DD library is updated on a regular basis and at no additional cost.

The ADT227Ex-HART is integrated with basic HART communication functions,

permitting users to monitor, control, and calibrate HART instrumentations.

It's an ideal device for calibrating, maintaining, and troubleshooting HART

instrumentations.

The onboard applications provide a useful selection of features including HART communicator,

high static differential pressure mode, pressure leak test, safety valve test, analog transmitter

calibration, unit converter, thermal calculator, and snapshots to name a few.

High static differential pressure mode uses two sensors, unique calculation technology to

achieve a differential pressure measurement to 0.002% FS at high static pressures. The leak

test will automatically calculate the pressure drop to determine a leak condition. The safety

valve test is a specialized task which captures the exact pressure release point by taking 10

readings per second during a valve crack test.

You will nd this and much more as we continue to develop new apps at Additel.

Targeted application features

The ADT227 calibrator can record pressure, temperature and electrical signals.

Recorded values can be displayed numerically or graphically to identify trending. The

ADT227 & ADT227-HART can store up to 500 results. each result can include up to

100,0000 recordings and each recording can record a maximum of 7 channel values.

These results can easily be exported to Additel’s application software. Each log

session is easily congured at a set interval and provides a date and time stamp with

each reading.

Users can remotely connect mobile devices to the ADT227 via Bluetooth with

an unobstructed distance up 20 meters. The included USB type-C comm port

and cable provide a hard wired communication option as well as charging for the

removeable Li-ion battery, which provides up to 12 hours of run time.

In addition to all the great features mentioned above, the ADT227 series is loaded

with time saving features like our builtin pressure and temperature converter, thermal

calculator, wiring diagram guide for assisting with electrical connections, a built-in

diagnostic center including intelligent alarm messaging and a real time error report

and comprehensive selftesting to help our customers get the very most out of their

investment in Additel calibration tools.
