The A323 ‘L’ series rugged, ultra-low range gravity referenced linear servo accelerometers deliver a 4 mA to 20 mA (closed loop) output. Tailored to low acceleration analysis, structural health monitoring, flight test, and civil engineering applications, the components provide accurate measurements over a range of ±0.1g to ±2.0g with a frequency response down to dc. They monitor acceleration down to 20 mg and are rugged enough to withstand up to 1,500g of mechanical shock. An optional 1g bias is also available. SHERBORNE SENSORS INC., Wyckoff, NJ. (877) 486-1766.
