Low Noise Sensors provide measurements in micro-G range.

Press Release Summary:




Designed for use in seismic and low level, low frequency motion studies, Models SA-107LN, SA-207LN, and SA-307LN are single-, 2-, and 3-axis servo accelerometers, respectively. In addition to DC-coupled zero output, units provide AC-coupled zero output, which eliminates tilt induced or offset errors. Self-contained units feature +15 Vdc operation and require no signal conditioning. Applications include floor vibration, seismic detection, antenna stabilization, and earthquake monitoring.

Low Noise Sensors Provide Measurements in Low Frequency Micro-G Range



Models SA-107LN, SA-207LN, and SA-307LN servo accelerometers from Columbia Research Labs are high sensitivity, ultra low noise sensors designed 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. On all units, low noise electronics used in conjunction with the force balance principle make possible measurements in the low frequency micro-G range. Aside from the traditional DC-coupled zero output, these accelerometers provide AC-coupled zero output which eliminates tilt induced or offset errors facilitating high amplification of the basic output. These accelerometers are self contained and provide high level, low impedance output. No signal conditioning is required in most applications. The units offer + 15 VDC operation and are available in a choice of package styles. SA-107LN, SA-207LN and SA-307LN accelerometers perform extremely well in applications such as floor vibration, building motion, seismic detection, antenna stabilization, and earthquake monitoring.
