A320 ‘L’ Series

Product catalog summary

Overview
The A320 ‘L’ Series Ultra-Low Range Linear Servo Accelerometer is designed for applications requiring precise low-range acceleration measurements. It features an ultra-low range of ±1/10g to ±2g, high-level output signal, and is fully self-contained, requiring only a DC power source and a readout or control device for operation. The device is extremely rugged, capable of withstanding shocks up to 1500g.

Benefits
The accelerometer's small size allows for easy integration into constrained spaces, and it operates over a wide temperature range from -18°C to +70°C.

Applications
This accelerometer is suitable for geophysical, seismic, and civil engineering studies, flight test monitoring, structural monitoring, and low acceleration analysis.

Notes

Full Range Output is defined as the peak-to-peak acceleration.
Non-linearity is determined by the method of least squares under constant acceleration conditions.
Zero offset is specified under static conditions with no vibration inputs.
Cross-axis Sensitivity is the output at 90 degrees when tested under static acceleration conditions.
For 1g biased units, the scale factor is 8mA/g.

Model Designation & Ordering Code
The model designation and ordering code is structured as A32g-0001- with options for g range and electrical connector type.
