DatasheetFor years, we have provided the most durable, accurate, quality pressure calibration products for field applications. The Additel 780 series 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 series offers two base ranges: to 70 bar and 200 bar. The base range establishes the maximum controlling range of the controller. Each configuration includes a control sensor which is preselected to the sensor range best suited for your application. External and internal sensors can be used which allows an expanded range and accuracy capability in the future.
There are also two controllers types that can be selected: The Additel 780S us the standard controller option without any measurement capability. The Additel 780 has expanded functionality including electrical measurement and HART and Profibus PA communication.
Modular design
Each unit comes with one intelligent pressure module configured to the many range offerings provided. Standard accuracy sensors (ADT160A-CPXXX) are silicone pressure sensors with a 1 year accuracy of 0.02% FS. The precision quartz sensors improve the 1 year accuracy specification to 0.01% of reading from 100% to 30% 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 can be equipped with 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 Intelligant 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 controller will require a nitrogen bottle for the gas
supply which makes it difficult to move the controller around
without have to move or connect another bottle.
Process functionality (excl. ADT780S versions)
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 Profibus PA communication, switch measurement capability and much more.
