FROM THE EDITOR: SMART, NETWORK-CAPABLE SENSORS WILL INCREASINGLY DRIVE OPPORTUNITIES IN THE SENSOR MARKET.

Article Excerpt
SBD notes that advancements in smart, network-compatible sensors will be a key factor driving the growth and expansion of diverse, high-volume applications for sensors. Sensors that are able to be more readily and cost-effectively integrated into data communication networks and to the Internet will enable users to monitor a plethora of data points to derive vital information to more effectively monitor and control their key applications and processes. The broader acceptance and proliferation of standards for connecting sensors to networks (i.e., the take-up of key features of the IEEE 1451 family, and the increasing penetration of the Ethernet bus technology in industrial environments) will help propel the real-world opportunities for sensors that offer intelligent electronics and plug and play network compatibility.

Key features to be afforded by smart sensor technology can include: self-identification (identifying the signals emanating from a specific sensor); connectivity (allowing the sensor to remotely provide measurement information and permitting the user to remotely update calibration information); self-compensation (internal compensation for imperfections in sensor behavior (e.g., non-linearity) with minimal or no user intervention); and self-correction...
