High-density thermocouple module for data acquisition

The National Instruments NI 9213 adds high-density thermocouple measurements to the NI C Series platform. Using the NI 9213, users can create a compact, modular data acquisition system to collect data from up to 16 independent thermocouples. The NI 9213 takes up less space than standard instrumentation in a measurement system and provides more channels for measurement with a sampling rate of 75 samples/s/channel, making the device both compact and efficient for high-channel systems.

Because of the flexibility of the C Series platform, the NI 9213 can be used in new or existing applications. The NI 9213, like other C Series modules, can be deployed as a quick measurement desktop data acquisition device with the NI USB-9162 single-module or NI CompactDAQ eight-module carriers. The NI 9213 can also be used in a remote measurement system over an ethernet or Wi-Fi connection with the NI WLS-9163 wireless C Series single-module carrier or as part of an embedded measurement and control system in NI CompactRIO hardware. With multiple NI 9213 modules in one chassis, NI CompactDAQ and CompactRIO are now able to support up to 128 channels of thermocouple measurement in a single system.

All 50 of the C Series I/O modules are designed as self-contained measurement modules, with the circuitry required for the specific measurement contained in the module itself. Analog-to-digital and digital-to-analog conversion occurs in the module before the data reaches the chassis.

The NI 9213 can also be combined with a variety of other C Series modules that take measurements such as acceleration, voltage, current, pressure and digital I/O. The modules can be moved from one platform to the other with no hardware modifications. Engineers can create solutions that scale across the C Series platform using the same applications developed in the NI LabVIEW graphical programming environment.
