Models 6243M6 and 6243M7 piezoelectric accelerometers are designed specifically for use in extremely high temperature environments such as aircraft and ground-based gas turbines. These accelerometers are designed for continuous operation at +1200˚F (+650˚C). The small size and light weight of these accelerometers facilitate installation in cramped locations with minimal structural support. The connector is .250 inch diameter which allows installation in cramped spaces.
