The NI Combustion Analysis System (CAS) is a low-cost, portable combustion analyzer based on the NI CompactDAQ platform. NI CAS includes all the hardware, I/O, and software you need to read, analyze, and log data from pressure sensors in an internal combustion engine.
You can choose from three NI CAS form factors: USB, Ethernet, or stand-alone NI CompactDAQ chassis. The USB and Ethernet systems can be tethered to a laptop or PC to interface with the software and log data via a USB cable or over a network. The stand-alone system contains a high-performance processor and standard laptop peripherals, so you can install NI-CAS Software directly on the NI CompactDAQ hardware. The stand-alone NI CAS does not require a laptop.
The NI USB CAS Lite features two unused hardware slots for customization, and the USB, Ethernet, and stand-alone CASs each feature five unused slots. You can select from more than 50 NI C Series I/O modules to add to any of the available NI CompactDAQ chassis slots and meet a variety of application needs. The NI Full Stand-Alone CAS does not have slots for I/O customization.
The NI USB CAS Lite has one NI 9411 (encoder input) and one NI 9215 (four simultaneously sampled BNC analog inputs, 100 kS/s) module. The USB, Ethernet, and stand-alone CASs each have one NI 9411 (encoder input) and two NI 9222 (eight total simultaneously sampled analog inputs at 500 kS/s) modules. The NI Full Stand-Alone CAS has one NI 9411 (encoder input), four NI 9222 (16 total simultaneously sampled analog inputs at 500 kS/s), one NI 9205 (up to 32 additional AI channels), one NI 9213 (16 thermocouple channels), and one NI 9269 (four analog output channels) module.
The ready-to-use NI-CAS Software works with three timebases: high-speed engine synchronous (cylinder pressure and so on), angular windowed time domain (knock, ion, and so on), and medium-speed time domain (temperatures, other pressures, and so on).
The combination of ready-to-use software and portable, modular I/O makes NI CAS the perfect combustion analysis system for in-vehicle, lab, or test cell applications.
