The Model MA21 miniature, low profile amplified piezoelectric accelerometers are designed to be used in Industrial test and automation environments including laboratory testing, modal studies, and test cells where head room is limited and where a low profile unit is desirable. The constant current low output impedance output combined with the ability to drive high load capacitance allows long runs of low cost cable without degradation of data.

The Model MA21 features a high natural frequency, a wide frequency range, and a flat sensitivity vs. temperature response over the temperature range. The seismic element is mechanically isolated from the mounting base, resulting in a low base strain sensitivity. The stainless steel materials are non-magnetic resulting in very low magnetic field susceptibility. These features, together with a sealed body, assure accurate and reliable data.
