Technical parameters of 3273A4 vibration sensor, including measurement range, resolution, temperature range, linearity, noise level, etc.
This document provides the outline and installation drawing for the Dytran 3273A triaxial IEPE accelerometer. It includes mounting recommendations, connector specifications, and mechanical dimensions needed for proper integration.
The drawing is accompanied by a performance specification sheet that lists sensitivity, frequency range, supply current, voltage compliance, operating temperature, and other electrical and environmental parameters for the 3273A series models.
| Weight | 3.0 grams |
|---|---|
| Sensitivity (3273A2) | 100 mV/g |
| Sensitivity (3273A4) | 50 mV/g |
| Supply Current Range | 2 to 20 mA |
| Compliance Voltage Range | +18 to +30 VDC |
| Operating Temperature | -60 to +200 °F |
| Frequency Range | 1 Hz to 10,000 Hz |
Prepare a surface at least .300 × .300 inches with flatness ≤ .0001 in and apply one drop of cyanoacrylate to mount the accelerometer.
Model 3273A2 has a sensitivity of 100 mV per g.
Do not exceed 20 mA; applying higher current can destroy the internal IC amplifier.
