Product introduction
UK Alphasense A+ and B+ series smart sensor description:
The A+ and B+ sensors are built on the field-proven and highly regarded A series and B series. All A+ and B+ sensors are backward compatible, with the same dimensions, performance characteristics, and outputs as the A and B series. Based on the popular A series and B series platforms, A+ and B+ feature integrated smart technology, providing a wide range of out-of-the-box benefits. A+ and B+ come pre-populated with over 30 sensor-specific parameters and over 8KB of free memory, with more than 15,000 memory slots, setting a new standard for plug-and-play sensors.
Key benefits of A+ and B+ integrated smart technology include: pre-calibrated sensors, traceability/path to market, maintenance, performance, compliance, interchangeability. This two-layer sensor design enables instrument manufacturers to standardize electronic hardware and identify instrument functionality based on sensor selection, offering many possibilities to streamline production, improve performance, and enhance end-user experience.
