Top-entry, constant current accelerometer for vibration analysis at elevated temperatures. Made from robust stainless steel throughout for long term analysis in harsh environments and up to 250ºC surface temperature; as the sensor head contains no electronics. An in-line charge amplifier connected with extra high-temperature cable (265ºC) can be located 5 metres from the heat source where temperatures are 120ºC or less. A further 5 metres (or longer) of overbraided cable connects to the junction box or data collector giving an output of 100mV/g. Available with a wide range of mountings.
