Analog Devices Inc. is offering a dual-axis accelerometer capable of withstanding up 175 degrees Celsius (342 degrees Fahrenheit) for ruggedized industrial applications. The device is based on what ADI calls the world's first high-temperature micro-electro-mechanical system (MEMS) technology. Today, applications using an accelerometer in a high-temperature environment, such as tools used in geological down-hole measurements, require complex compensation circuitry to ensure that readings are not skewed by temperature. The new iMEMS ADXL206, on the other hand, has virtually no quantization errors or other non-monotonic behaviors over its entire operating range, from -40 degrees to +175 degrees Celsius, according to ADI (Norwood, Mass.)
