Charge output accelerometers require a charge amplifier to convert the signal to a voltage as required by readout instrumentation. This type of accelerometer can handle higher temperatures, and are normally recommended for applications with temperature requirements above 185°C. DJB's range of charge accelerometers tolerate up to 400°C.
Voltage output IEPE accelerometers require minimal instrumentation to connect them to readout equipment; only a 15-35v DC supply, due to the integrated charge to voltage converter. Due to the integrated circuitry, these accelerometers are generally not designed to exceed temperatures of 185°C, unless a water cooled accelerometer is used,
Water cooled accelerometers are available in both charge and voltage output versions, with high temperature testing solutions up to 900°C.
