A320 Series

Product catalog summary

Overview
The A320 Series Ultra-Low Range Linear Servo Accelerometer is designed for applications requiring precise low acceleration measurements. It features a compact design, making it suitable for integration into constrained spaces, and operates effectively across a wide temperature range from -18°C to +70°C.

Features

Ultra-low range measurement capability from ±1/10 g to ±2g.
High-level output signal for easy interfacing.
Self-contained system requiring only a DC power source and a readout or control device.
Rugged construction capable of withstanding shocks up to 1500g.

Applications

Geophysical, seismic, and civil engineering studies.
Flight test monitoring.
Structural monitoring.
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 1g in cross-axis when tested under static acceleration conditions.

Model Designation & Ordering Code
The model designation includes the g range and electrical connector type, with solder pins as standard.
