For years, we’ve provided the most durable, accurate, quality pressure calibration products for field applications. The Additel 780 controller incorporates the same durability, accuracy, and quality into a new bench top controller packed with features and functionality that is remarkably easy to use. The Additel 780 offers two base ranges: to 1,000 psi (70 bar) and to 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 your application. External and internal sensors can be used which allows for expanded range and accuracy capability in the future.
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 Additel 780 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 Additel 780 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 make it
difficult to move the controller around without having to move or
connect to another bottle. The Additel 780 is unique in that with the
optional electric pump, you can generate pressures to 1,000 psi (70 bar)
without the need of a gas bottle.
Process Functionality
The 780 Pressure Controller
is considered to handle a very wide range of applications which 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.
