Additel ADT227EX – Intrinsically Safe Documenting Process Calibrator

Additel’s new Multi-functional 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. The ADT226 is a powerful yet cost effective process calibrator, which has an ATEX certified intrinsically safe option – ADT226Ex allowing you to perform calibration work in the harshest of environments. We’re confident these new tools will not only meet your calibration requirements but will make metrology simple for you.

Additel offers several versions of the ADT226 and ADT227 calibrator, with options including documentation, HART communication as well as intrinsically safe models. The chart below provides a brief overview of several main points for each:

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.

The calibrator can record pressure, temperature and electrical signals readings for a long period. Recorded values can be displayed numerically or graphically to identify trending. ADT227 & ADT227-HART can store up to 500 results. each result can record up to 7 channels with up to 100,0000 readings in each channel. These results can be easily exported to Additel application software. Each log session is easily configured at a set interval and each reading is provided with a date and time stamp.

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 the 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 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 field 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.

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 delivers highly improved thermocouple measurement capabilities by vastly improving the cold junction compensation (CJC) specifications and a much improved stabilization time.

The demands of remote calibration work can be challenging. The ADT227series 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 confidence in your critical calibration and measurement work.
