Engineers at the Honeywell Inc. Solid State Electronics Center in Minneapolis are offering a high-temperature magnetic sensor called the HTMC1021D for proximity sensing, position/angle sensing, and signal transformation. The device, which operates in temperatures between -55 and 225 degrees Celsius, works in applications where flux sensors traditionally were used. It comes in a ceramic dip package rugged enough to handle high vibration and other hostile environments, Honeywell officials say. This device is based on Honeywell`s proprietary silicon on insulator technology for military and aerospace applications.
