MODULAR DESIGN
Each unit comes with one Intelligent Pressure Module configured to the many range offerings provided. Standard
accuracy sensors come with a 1 year accuracy of 0.02% FS. The precision accuracy models improve the 1 year
accuracy specication to 0.01% of reading from 30% to 100% of range. Each sensor has been specially aged, tested
and screened before assembly. After assembly each sensor is temperature compensated over the range of 0°C to
50°C. The 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 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 make it
difcult to move the controller around without having to move or connect to another bottle.
The 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 of a gas bottle.
The 780 Series 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 Probus PA communication,
switch measurement capability, and much more.
