The sensitivity of piëzo electric elements is largely depending
on the dimensions of the element. As such, a higher sensitivity
will usually result in a larger transducer whereas the frequency
range is inverse proportional to this. The APTech general-purpose
accelerometers have been designed to cover a wide range of applications
and offer medium range in sensitivity and frequency response.
The annular shear construction makes these accelerometers relatively
insensitive to external influences such as temperature changes,
base-strain and magnetism. Each transducer is delivered with an
individual calibration-chart, connection cable and mounting stud
(if applicable). Type AP37 and AP2037 are ideally suited for control-loop
applications in vibration exciter systems. Type AP90 is designed
for leak detection on pipelines. Type AP98-100 and AP98-500 are
low-cost IEPE accelerometers with excellent specifications and
proven long-term stability.
