Comment effectuer une mesure d'encodeur en quadrature Les encodeurs rotatifs servent à mesurer le déplacement rotatif d'un axe. La figure n°1 montre les composants de base d'un encodeur rotatif : une diode électroluminescente (LED), un disque et un capteur de lumière de l'autre côté du disque.
Comment effectuer une mesure de thermistance Les thermistances, comme les sondes RTD, sont des semi-conducteurs thermosensibles dont la résistance varie avec la température. Les thermistances sont constituées d’un matériau semi-conducteur d’oxyde métallique encapsulé dans une petite bille d’époxy ou de verre.

Wi-Fi DAQ Frequently Asked Questions Wi-Fi data acquisition is an extension of PC-based data acquisition to measurement applications where cables are inconvenient or impractical. NI Wi-Fi data acquisition (DAQ) devices combine IEEE 802.
Wireless Environmental Monitoring Environmental monitoring ranges from examining the integrity of soil, water, and air to regulating the temperature and humidity associated with the indoor storage of critical assets such as servers or perishables.
Wireless Industrial Remote Monitoring Industrial monitoring involves monitoring and controlling different plant, factory, or manufacturing conditions while logging data to enterprise systems.
Wireless Structural and Seismic Monitoring Engineers and scientists are using the latest sensing and measurement techniques to enable a more intelligent and safer civil infrastructure for existing and new structures around the world.
Simple. Complete. Ethernet Data Acquisition. The NI ENET-9000 series includes measurement quality data acquisition devices that were designed to make taking distributed measurements over standard Ethernet simple.
Wi-Fi Security Primer for Data Acquisition Wi-Fi network security has matured significantly in the IT space over the past ten years, making it a viable solution now for data acquisition applications. Because Wi-Fi uses air as its physical media, it offers unique security challenges beyond those of a wired system.
