This document describes the features and characteristics of the 3133A3 ultra-miniature accelerometer and its family, including ideal low-frequency response, physical parameters, and performance specifications.
This outline and installation drawing provides the mechanical layout, mounting surface preparation, and cable options for the Dytran 127-3133A triaxial accelerometer. It shows dimensions in inches (with metric equivalents), recommended flat mounting surface, adhesive usage, and part numbers for removal tools and mounting wax.
The accompanying performance specification lists the sensor sensitivities, frequency ranges, weight, housing material, connector type, and power supply requirements for the 3133A1, 3133A2, and 3133A3 models, enabling engineers to select the appropriate variant for their application.
| Model Number | PS3133A3 |
|---|---|
| Sensitivity (mV/g) 3133A1 | 10 |
| Sensitivity (mV/g) 3133A2 | 2 |
| Sensitivity (mV/g) 3133A3 | 5 |
| Frequency Range Axis 1 & 2 | 0.25 to 7000 Hz |
| Frequency Range Axis 3 | 0.25 to 10000 Hz |
| Weight (without cable) | 0.8 g |
| Housing Material | Titanium |
| Connector Type | 4‑pin |
| Power Supply Voltage | +18 to +30 VDC |
Prepare a flat mounting surface of at least .20 diameter, flat to .0001 TIR, and apply one drop of cyanoacrylate adhesive before mounting the accelerometer.
The device operates from a compliance voltage of +18 to +30 VDC.
The accelerometer weighs 0.8 grams (approximately 0.03 oz) without the cable.
