Additel Instruments Digital Pressure Controllers Additel 780 Series

Additel Instruments Digital Pressure Controllers Additel 780 Series

Additel Digital Pressure Controllers provided the most durable, accurate, quality pressure calibration products for field applications. The Digital Pressure Controllers Additel 780 Series controller incorporates the same durability, accuracy, and quality into a new benchtop controller packed with features and functionality that is remarkably easy to use.

Digital Pressure Controllers Additel 780 Series offers two base ranges: 1,000 psi (70 bar) and 3,000 psi (200 bar). The base range establishes the maximum controlling range of the controller.

Each configuration includes a control sensor in which you can preselect the sensor range best suited to your application. External and internal sensors can be used which allows for expanded range and accuracy capability in the future.

Additel Digital Pressure Controllers Modular Design

Each unit comes with one Intelligent Pressure Module configured to the many range offerings provided. Standard accuracy sensors (ADT160A-CPXXX) are silicon pressure sensors with a 1-year accuracy of 0.02% FS. The precision quartz based sensors improve the 1-year accuracy specification to 0.005% of reading + 0.005% FS.

Each sensor has been specially aged, tested, and screened before assembly. After assembly, each sensor is temperature compensated over the range of -10°C to 50°C. The Digital Pressure Controllers Additel 780 Series allows for one internal pressure sensor and one external pressure sensor.

The modular design of this unit provides for interchangeability of both the internal and external sensors with other Intelligent Pressure Modules. In addition to the Intelligent Pressure Modules, the Digital Pressure Controllers Additel 780 Series has a built-in barometric sensor. This allows for switching between gauge pressures to absolute pressures.

Standalone Solution

Typical pressure controllers will require a nitrogen bottle for the gas supply which makes it difficult to move the controller around without having to move or connect to another bottle. The Digital Pressure Controllers Additel 780 Series is unique in that with the optional electric pump, you can generate pressures to 1,000 psi (70 bar) without the need for a gas bottle.

Process Functionality

The Digital Pressure 780 Series is considered to handle a very wide range of applications that may normally require a pressure calibrator. Built-in capability includes current and voltage measurement capability, 24-volt loop power, HART®, and Profibus PA communication, switch measurement capability, selectable analog output, and much more.

Features

  • Pressure ranges from vacuum to 3,000 psi (200 bar)
  • Precision accuracy models to 0.01% of reading
  • Standard model accuracy of 0.02% of the full scale
  • HART Communication and Profibus PA
  • Control stability of 0.003%FS
  • Easy-to-use icon-based user interface
  • ISO 17025-accredited calibration w/data included
