IMI Sensors has developed a new High Temperature, Hazardous Area Approved
Charge Accelerometer Model EX615A42 to be used in power generation vibration
and other high temperature vibration monitoring applications. This new model can
operate in temperatures up to 500 °F (260 °C) and can be paired with one of IMI
Sensors’ complementary differential charge amplifiers.
