Powerful LabView acquisition and control software with a wide range of features is available for many Armfield products.

In many cases, the latest software and interface systems are also available as updates to existing equipment.

Ordering Specification

Tabular display of measured and calculated data
Facility to add notes to a particular sample
Notepad facility
Flexible graphing facilities for users to plot measured and calculated data
Automatic scaling and formatting of graph axes
Graphs update in real-time
Detailed help document
Automatic port recognition


The software as supplied consists of a Display page, which shows all of the variables and controls, a Data page, which enables tabular and graphical data to be processed and displayed, and a Settings page, which gives access to control and communications settings. There is also an Oscilloscope page which enables one or two variables to be processed at much higher sampling speeds, for the analysis of rapidly changing processes.

The software is based around the National Instruments LabVIEW™ environment. The software is supplied with a runtime version of LabVIEW™, which enables full operation of all functions.

Customise and Develop

If the user has access to a full version of LabVIEW™, then they will be able to view and modify the VI (Virtual Instrument) files that form the basis of the software.

This means  customised software can be produced in order to perform additional experiments with the equipment or investigate alternative control methods.


The communication between hardware and software on Armfield apparatus is controlled by a common interface unit, referred to as an IFD card. Common versions of the interface are the IFD5 which is a small black-boxed unit, the IFD7 which packages the interface with an inverter in a stainless steel housing, and is used to control Armfield Capture units, and a PCB-only version, which is fitted inside the electrical enclosure of more complex equipment. The interface connects to the PC via a USB socket. It is supplied with an information file which enables Windows to create a virtual serial port for the device. Information on installing the interface in Windows can be found on the software CD supplied with your apparatus. The interface connects to the equipment using a 50-way cable that carries signals from sensors, etc. The connections are described overleaf. By using the table in conjunction with that in the instruction manual provided with the equipment, the channel descriptions and scaling for each sensor can be determined.


The Armfield software is divided into four screens, which are navigated using the tabs at the bottom of the window. The available screens are Process, Data, Settings and Oscilloscope. The Oscilloscope screen is only applicable with certain products.

Process tab:

The first screen shown when the software is loaded is the Process screen. This generally shows a diagram of the equipment, or a process schematic, along with data boxes which display real-time data from the sensors connected to the equipment

Data tab:

The data tab contains numerous pages associated with storing and processing the experimental data. Pages are selected using a series of tabs at the left-hand side of the screen. Some pages are not available in all types of software.

Results table:

The results table shows a tabulated view of the experimental results. Measured and calculated values are shown together with the time at which the sample was recorded.

Settings tab:

The settings tab provides access to the data-logging options and sensor calibration screens. This tab contains a further set of options to the left-hand side.

Oscilloscope tab:

On certain equipment where very fast transients occur, an oscilloscope page is provided to capture and analyse these events.


Computer: A Windows PC (not supplied)

For editing/modification: A full version of LabVIEW™ (not supplied)
