Temperature Measurements

The Coda data acquisition software platform supports the LXI-based EX1048 precision thermocouple instrument made by
VXI Technology inc. to address the most demanding temperature measurement applications. LXI is an instrumentation platform based on industry standard Ethernet technology designed to provide modularity, flexibility and performance to small- and medium-sized systems.

The high-density, compact 48-channel thermocouple instrument provides exceptional temperature accuracy and stability. Thanks to direct Ethernet connectivity, instrument installation and set-up has never been easier: Simply plug-in a standard network cable and start taking a measurement. Multiple devices are easily integrated and synchronized via a trigger bus. The EX1048 also provides an ideal solution for distributed measurement applications by reducing cabling and installation expense.

The extreme measurement precision is achieved by end-to-end calibration where a highly accurate calibration source provides reference signals that are applied prior to analog filtering and gain circuits to compensate for drift, aging or temperature variations. The system accepts all standard thermocouple types including J, K, T, E, S, B, R, N.

The Coda software allows you to configure measurement set-ups with hundreds of channels within a very short time and to handle these high-channel count applications safely and efficiently. Key features include client/server architecture, SQL data base for parameter management, automatic frontend identification, real-time analysis of virtual channels using mathematical functions, alarm functions with user-definable alarm actions for every channel, data replay and data export into common file formats.

EX1048 Measurement Hardware Specifications:

• Up to 48 differential measurement channels
