The Columbia Models SA-307TX and SA-307HPTX are force balance accelerometers capable of measuring DC and low frequency acceleration simultaneously in three axes. These sensors are self-contained and provide a high level, low impedance output. No additional signal conditioning is required in most applications.

The Model SA-307TX is a low cost design and is well suited for many OEM and general-purpose industrial applications. The Model SA-307HPTX incorporates Columbia's patented "HP" torquer design providing improved accuracy and repeatability in adverse shock and vibration environments. Consult the factory for customized versions of these sensors.
