Additel ADT 227 [ADT227-HART] Multifunction Process Calibrator With HART Communication. The Additel 227 multifunction process calibrator is lightweight, highly portable, and utilizes an advanced color LCD screen to help ensure the user can easily see. All models in the 227 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 critical calibration and measurement. The 227 provides 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 227 comes 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 227 Ex intrinsically safe model has passed the most stringent testing by certified organizations to acquire intrinsically safe certificates, ATEX, IECEX, CSA and UKCA. The explosion-proof grade (Ex ia IIC T4 Ga), can be widely used in potentially explosive environments, such as oil / gas platforms, oil refineries, chemical and petrochemical plants, pharmaceutical industries, energy and gas processing industries. Each intrinsically safe calibrator has an advance transflective color LCD display which has enhanced visibility when viewed in direct sunlight. The 227 non-Ex version is equipped with a 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. The built-in full HART communicator will work with most HART transmitters on the market. The ADT227-HART contains an extensive DD library and 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. Users can remotely connect mobile devices to the 227 via a Bluetooth connection at an unobstructed distance of 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 and replaceable Li-ion battery, which provides up to 35 hours of run time.
