Additel’s ADT761A automatic pressure calibrators are fast to pressure, up to 7,000 kPa, with interchangeable pressure modules, task management and HART communications with updateable DD files
Additel’s new ADT761A series calibrators provide breakthrough features and additional value to their existing line of automatic pressure calibrators. The ADT761A has many improvements. These include increased pressure range to 7,000 kPa, interchangeable internal pressure modules, optional precision models to 0.01%FS, increased speed to pressure, ability to read two external pressure modules, touch screen display, Wi-Fi, Bluetooth, and Ethernet communications, double the original battery life, and more!
The Additel 761A-500 will generate and control from vacuum pressures up to 3,500 kPa gauge. Both gauge and absolute pressures can be realised due to a built-in barometer. Each unit comes with a CP500 module (-86 to 3500 kPa) for the high range and the low range can be preconfigured based on the variety of modules available down to 70 kPa.
The Additel 761A-1K will generate and control from vacuum pressures up to 7,000 kPa gauge. This unit can typically achieve 7,000 kPa in less than 45 seconds. Like the ADT761A-500, both gauge and absolute pressures can be realised due to a built-in barometer. Each unit comes with a CP1K module (-86 to 7,000 kPa) for the high range and the low range can be preconfigured based on the variety of modules available down to 200 kPa.
The Additel 761A-LLP is designed for low pressure calibration and comes with a ±75 mbar high range module and a low range module of your choice ranging from ±50 mbar to as low as ±0.62 mbar. This unit has an accuracy of 0.05%FS with control stability better than 0.005%FS. All measurements can be made in differential or gauge pressures.
The Additel 761A-D also provides differential and gauge measurement which covers the range of -95 to 250 kPa. This unit comes with a CP35 module -95 to 250 kPa and one low range module of your choice ranging as low as ±25 mba). Each ADT761A-D can be preconfigured with the modules that fit your need to give you the best precision at the pressures you perform calibrations.
ADT761A-APXR Precision Accuracy Options
The Additel 761A series includes a precision accuracy option which provides an accuracy of 0.01%FS. This calibrator option includes a single non-removable sensor and can measure absolute and gauge pressures. Model configurations are available from 100 to 7,000 kPa.
The Additel 761A-BP is designed for calibration of barometer sensors. With a range of 100 to 1200 hPa and an accuracy of 0.01%FS, this unit is ideal for calibration on the bench or in the field.
