New Sampling/Sensor Initiative “Electrifying” NeSSI - Wireless to the Rescue?

This article explores the application of wireless technology in NeSSI systems, specifically focusing on the benefits and configurations of wireless signal transmission between the sensor analytical manager (SAM) and the controller/analyzer. The aim is to improve the efficiency and remote operation of sampling systems, such as NIR and RAMAN analyzers, by eliminating the need for wiring harnesses and enabling wireless communication.
