Sherborne Sensors A320 Series Ultra Low Range Accelerometers

Product catalog summary

Overview: The Schaevitz® A320 Series is a line of high precision, gravity-referenced, ultra-low range linear servo accelerometers designed for industrial and aerospace applications. These accelerometers are robust, shock-resistant, and suitable for a variety of uses including geophysical studies, flight test monitoring, and structural monitoring.

Features:

Self-contained system requiring only a DC power source and a readout/control device.
High-level output signal with ranges from ±0.1g to ±2g.
Extremely rugged, capable of withstanding 1500g shock.

Applications:

Geophysical, seismic, and civil engineering studies.
Flight test monitoring.
Structural monitoring.
Low acceleration analysis.

Environmental Characteristics:

Operating Temperature Range: -18°C to 70°C.
Survival Temperature Range: -40°C to 70°C.
Constant Acceleration Overload: 50g.
Shock Survival: 1500g, 0.5msec, ½ sine.
Vibration Endurance: 35g rms, 20 Hz to 2000 Hz sinusoidal.
Environmental Sealing: IP65.
