Additel ADT295 Hart Communicator
Product Description
The ADT295 Field Device Communicator is a versatile, all-in-one solution for configuring, calibrating, diagnosing, and managing HART®, FOUNDATION™ Fieldbus, and Profibus PA instruments. Designed for industrial process applications, it supports transmitters, positioners, and other field devices used across the oil & gas, chemical, power, and process industries.
With both online and offline operating modes, the ADT295 communicates directly with installed field devices during operation while also supporting calibration, testing, and troubleshooting in metrology laboratories, instrument shops, and maintenance facilities. Integrated loop power and advanced diagnostic capabilities eliminate the need for external power supplies, resistors, and other accessories, allowing technicians to complete more tasks with a single handheld device.
Overview
| Field-Tested Speed and Usability |
|---|
|
In the field, every extra second spent waiting on a device is time wasted that could be used for other tasks. Early trials of the ADT295 point to real gains here: testers consistently describe device communication and menu navigation as noticeably faster than what they're used to with other handheld communicators. The difference traces back to how the interface was built, organized around real technician workflows rather than underlying protocol architecture, so common tasks take fewer steps to complete. Testers have specifically pointed to routine calibration checks as an area where the streamlined navigation saves noticeable time. |
| FREE DD library updates - no fees or subscriptions |
|
Additel doesn't charge a fee or a subscription for DD library or firmware updates — there's no support contract required just to keep the communicator current. With pre-installed libraries supporting over 2,600 HART, FOUNDATION Fieldbus, and Profibus PA devices, the ADT295 is ready to communicate with a wide range of field instruments right out of the box. Built-in Wi-Fi and Bluetooth keep the ADT295 connected without extra hardware. As new devices come to market, a one-click update over Wi-Fi refreshes the DD library directly on the unit, with no computer, no IT involvement, and no complicated procedure required. Whether it’s a routine library refresh or a firmware update, the process stays the same: connect, download, and the ADT295 is ready for the next device in your plant. |
| Comprehensive Process Signal & Pressure Calibration |
|
Designed to streamline field calibration, the ADT295 supports autoranging voltage measurement, current measurement, current output, and an integrated 24 V loop power supply for testing and calibrating AI and AO cards, all from a single handheld. Voltage and current readings are accurate to 0.01% RD, and the loop power supply outputs 24 V with up to 30 mA of drive capacity, enough to power a transmitter directly during testing without sourcing external power. Every unit ships standard with a traceable, ISO/IEC 17025-accredited calibration, so it’s ready to use as a reliable reference from day one. By connecting an external Additel digital pressure module, users can also calibrate pressure transmitters, reducing the need for multiple instruments and improving maintenance efficiency. |
