Cryogenic ICP® Accelerometers for Extreme Temperatures
Cryogenic ICP® accelerometers are specifically engineered to function reliably at temperatures significantly below the conventional -65 ºF (-54 ºC) operating limit faced by most voltage mode sensors. Their design incorporates advanced, specialized built-in cryogenic circuitry along with precision quartz shear sensing technology, which collectively enhance the sensor’s durability and performance in extremely harsh and demanding environments such as liquid nitrogen. Each accelerometer is hermetically sealed and undergoes rigorous individual testing to accurately determine the thermal coefficient of sensitivity at an ultra-low temperature of -320 ºF (-196 ºC), guaranteeing dependable operation and highly precise measurements. These sensors have a proven track record of successful deployment in extreme conditions, including their use in the presence of liquid helium during the critical structural testing of rocket boosters.
Applications:
Cryogenic Pumps
Rocket Motors
