Undergoing extensive testing in Europe, the Models SA-107LN, SA-207LN, and SA-307LN servo accelerometers prove highly viable and reliable for structural health monitoring in a variety of situations. Tailored for use in seismic and low level, low frequency motion studies, the SA-107LN is a single-axis unit and the SA-207LN and SA-307LN are two- and three-axis units, respectively. Each employs low noise electronics used in conjunction with force balance principles that make measurements possible in the low frequency micro-G range. The accelerometers provide AC-coupled zero output, which eliminates tilt induced or offset errors facilitating high amplification of the basic output. Self contained with no signal conditioning required in most applications, they are powered with 12 to 15 Vdc and are available in a choice of package styles.
