DatasheetThe Additel 762 Automated Pressure Calibrator is unlike any other pressure calibrator on the market. This revolutionary product is a complete turnkey solution for automation of pressure calibration work up to 10,000 PSI.
Designed for use in both the field and the laboratory, the portability and accuracy of this state-of-the-art product will quickly become the favorite go-to calibrator for lab personnel and field technicians alike.
With fully automated support for calibration of pressure transmitters, switches, dial and digital gauges and sensors, including HART/PROFIBUS devices in conjunction with a fully integrated task feature, data collection and Wi-Fi connectivity, we had our customer’s needs in mind when designing our most capable pressure calibrator to date.
| Description |
|---|
| Dual-Range Accuracy to 0.01% FS |
| The ADT762 includes the unique ability to automatically switch between different internal calibrations depending on the current control pressure of the ADT762. Additel provides calibrations unique to each ADT762 for ranges of 0-3,000 PSI (200 Bar) and 0-10,000 PSI (700 Bar). As the calibrator is pressurized, it will automatically select the best calibration data for any specific control pressure. This means the accuracy option of 0.01% or 0.02% FS would apply to both the 10,000 psi and the 3,000 psi ranges. Pressure calibration range selection can be set to “auto” mode so the calibration range is automatically selected by the ADT762 based on the set point pressure, or the calibration range can be manually selected. |
| Built-in Auto-Purge Application |
| Purging hydraulic calibration systems can be challenging and time consuming. The ADT762 has been designed with an integrated auto-purge system that saves time, money and frustration by completely automating the removal of air from the system. With the push of a button, the ADT762 quickly manages the system purging. This helps to free up time for technicians to attend to other needs. |
| Documented Task Feature |
| The powerful documented calibration task application allows users to quickly create and execute tasks without the need for a PC or tablet. The ADT762 automatically analyzes errors, generates test reports, while storing results locally. The Additel 762 can support up to 1000 documented tasks which can be stored and recalled at any time to help save time and money. |
| Dual-Mode Hart Communication |
| HART pressure transmitters can be directly maintained and calibrated without any other equipment or tools. The ADT762 provides an automatic HART calibration mode as well as a manual mode. This dual-mode HART communication function not only provides an efficient and convenient interoperability mode for DUT, but also supports access to a fully HART capable calibrator. |
