This week we added another module to the iTestSystem compatibility list. One of our iTestSystem users recently needed to collect data from thirty-two (32), 4 to 20 mA current sensors along with their vibration measurements. National Instruments (NI) recently introduced a new C-Series current module, the NI-9253, that was a perfect fit for this application.
The NI-9253 module has eight (8) simultaneous sampled (50kHz max), +-20 mA, 24-bit input channels. It has several diagnostic features to ensure your system is operating nominally at all times with open channel detection, power supply detection, and configurable thresholds. The NI-9253 has eight LEDs that indicate the status of each channel and the power supply so a user can easily determine the system’s status in the field. The NI-9253 also features a number of programmable hardware filters (Butterworth and comb) to reduce signal noise.
For advice about using the NI-9253 in iTestSystem monitoring applications or with custom cRIO RT and FPGA control applications contact Mark Yeager or Chase Petzinger.

Here at Integrated Test & Measurement, we love diving into the nuts and bolts of how things work. While setting up a project using 120-ohm strain gages with the NI-9237 module, I found myself reflecting on the history and technical reasons why 120 ohms became the original standard for strain gages. As it turns out,…
