Meggitt model 6243M8 and 6243M9 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 +1000˚F (+538˚C). The small size and light weight of these accelerometers facilitate installation in cramped locations with minimal structural support.

6243M8 and 6243M9 incorporate Meggitt’s MC2 shear mode crystal. The 6243M8 has its sensitive axis located in line with the mounting screw. The 6243M9 has its sensitive axis located perpendicular to the mounting screw. The sensing elements and integral shield are isolated from the case. The accelerometer output is terminated through a 10-32 coxial receptacle. The dash numbers at the end of the model number define an integral coaxial high temperature softline cable that is permanently installed on the 10-32 connector.
