Last Revised: 2012-08-31 15:35:38.0 16-Channel Thermocouple Module NI 9213 Built-in CJC (cold-junction compensation) Autozero channel for offset error compensation High-speed mode for up to 1,200 S/s (aggregate) J, K, T, E, N, B, R, and S types supported 250 Vrms channel-to-earth ground safety isolation Included backshell kit (NI 9940) for strain relief 24-bit ADC for up to 0.02 °C measurement sensitivity Overview The NI 9213 is a high-density thermocouple module for NI C Series carriers designed for higher-channel-count systems. With this module, you can add thermocouples to mixed-signal test systems without taking up too many slots. The NI 9213 is similar to the NI 9211 four-channel thermocouple module except it features four times the channel count and almost 100 times the sample rate. You can use up to eight NI 9213 modules in an NI CompactDAQ chassis or CompactRIO chassis for 128 thermocouple measurements in a single chassis, or deploy a single module in any of the USB, Ethernet, or Wi-Fi carriers for C Series modules. Each shipping kit contains: -NI 9213 module with spring-terminal connectivity -NI 9940 backshell for cabling and strain relief -Spring-terminal tool for signal wire insertion Back to Top Requirements and Compatibility OS Information Driver Information Software Compatibility Real-Time OS NI-DAQmx LabVIEW Windows NI-RIO LabWindows/CVI Measurement Studio SignalExpress Visual Basic Visual C# Visual C++ Visual Studio Visual Studio .NET Back to Top Comparison Tables 1/8 www.ni.com Thermocouple Module Channels Sample Rate Resolution Feature NI 9213 16 1,200 S/s 24-bit Lowest cost/channel NI 9219 4 50 S/s/ch 24-bit Channel-to-channel isolation NI 9211 4 14 S/s 24-bit Low-channel count Back to Top Application and Technology Channel Density for High-Channel-Count Systems Temperature measurements can vary greatly over the different components in a machine, the surface of a device, or the volume of a given space. By taking more temperature measurements, you can better quantify the thermal gradients and achieve more accurate test results. The NI 9213 was designed with density in mind to enable a large number of thermocouple channels in a compact space. With up to eight NI 9213 modules installed in an NI CompactRIO or NI CompactDAQ chassis, you can measure up to 128 thermocouples in a system that fits inside a 9 by 9 by 26 cm box. For even more portable temperature measurement systems, you can install the NI 9213 into one of the single module carriers for NI C Series modules to make 16-channel thermocouple measurements over USB, Ethernet, or Wi-Fi (802.11b/g). CJC and Autozero for a More Accurate Measurement The NI 9213 has built-in cold-junction compensation (CJC) to eliminate error caused by the physical connection of the sensor to the instrumentation. The contact of two dissimilar metals creating a voltage potential is the principle on which thermocouples are designed, and, as such, the contact of the dissimilar thermocouple metal with the spring terminal must be removed from the calculation. This is done through a process known as cold-junction compensation, with the cold junction being the mating of the sensor to the instrument. All NI instrumentation designed for thermocouple measurement contains CJC circuitry including the NI 9211, NI 9219, and NI 9213. In addition to CJC, the NI 9213 features an extra, internal-only channel known as the autozero channel. By measuring the autozero channel at the beginning of each channel scan, you can eliminate further offset errors to provide a more accurate temperature measurement. C Series Compatibility The NI C Series hardware family features more than 50 measurement modules and several chassis and carriers for deployment. With this variety of modules, you can mix and match measurements such as temperature, acceleration, flow, pressure, strain, acoustic, voltage, current, digital, and more to create a custom system. Install the modules in one of several carriers to create a single module USB, Ethernet, or Wi-Fi system, or combine them in chassis such as NI CompactDAQ and CompactRIO to create a mixed-measurement system with synchronized measurements. You can install up to eight modules in a simple, complete NI CompactDAQ USB data acquisition system to synchronize all of the analog output, analog input, and digital I/O from the modules. For a system without a PC, CompactRIO holds up to eight modules and features a built-in processor, RAM, and storage for an embedded data logger or control unit. For higher-speed control, CompactRIO chassis incorporate a field-programmable gate array (FPGA) that you can program with NI LabVIEW software to achieve silicone-speed processing on I/O data from C Series modules.
