Do you recognize the situation? You want to do a measurement, and gather your PXI, a front-end and some sensors. Soon you realize that it will take much more time than you anticipated. You have to connect the power supplies of the sensors to an external power supply, and – even more annoying – one of the sensors you want to measure has a current output. Half a day later you are looking at your measurement results, and you have to admit that the signal quality is not as good as it should be. The quick and dirty wiring of the front-end maybe was not the best idea after all.
We have encountered this situation, and we grew tired of it. So, we developed a solution. Today, after elaborate testing on our own set-ups, we are ready to share it with the world. And when we say testing, we do mean testing. We stacked eight of these front-ends, and used them during a three month long experiment on an agricultural machinery. Vibration, dust, high temperatures (up to 50 degrees Celsius external temperature), our set-up has it all. At the end of those three months our front-end delivered perfect data just as at the start.
Specifications:
- shielded body and shielded connectors
- three power supplies available, independently selectable per input
- compatible with most National Instruments PCI and PXI Data Acquisition cards
- pull-up and pull-down selectable per channel
- conversion from current to voltage per channel
- one or two measurements per connector
- easily stackable for large set-ups
- easy connection of the NI cable, power supply and 8 digital IO on the back
The front-end on the picture supports up to 16 signal connectors, but we also offer a variant with only 8 connections, ideal for differential measurements. If required, connection cables can be contained. We can even provide entire measurement set-ups, including software. Contact us for your measurement challenge!
We will shortly launch alternative versions with other connection options. Please contact us if you have specific questions or requests. You can also visit us at our booth at NIDays on September 27th.
