What is a high-temperature accelerometer?
A high-temperature accelerometer is a piezoelectric sensor that measures accelerations. It works as a spring-mass system and is often applied to capture or monitor dynamic processes, i.e. vibrations or combustion fluctuations. Thanks to the PiezoStar crystal, it withstands temperatures of 700°C (1.300°F) and up to 1000°C in the short term. Through differential technology and shear design, low noise and high accuracy are achieved. An especially isolated hardline cable capable of such high temperatures connects the sensor with the charge amplifier.
