AP Series Accelerometers

APTech general purpose accelerometers are designed to cover of a wide range of applications without the need of having another sensor for each measurement-job. The sensors are optimised for wide frequency- and amplitude range while having medium range dimensions and weight. The annular shear construction makes these accelerometers relatively insensitive to external influences such as changes in temperature, base-strain and magnetic fields. Type AP90
has been specifically designed for leak detection on pipelines. Types AP37 and AP2037 are ideally suited for control-loop applications in vibration excitation systems.
