This document describes the specifications and performance characteristics of the 3049E Series IEPE accelerometers, including weight, size, sensitivity, frequency range, maximum vibration and shock, etc.
The 3049E Series consists of four IEPE accelerometer models designed for high‑frequency vibration measurement. Each model shares a common ceramic annular shear element and titanium‑alloy housing, with variations in sensitivity and mounting style.
Key specifications include sensitivities of 10 mV/g or 100 mV/g, a frequency range up to 10 kHz, resonant frequency of 35 kHz, and robust environmental ratings such as 600 g peak vibration and 5000 g peak shock. Electrical characteristics feature a supply current of 2‑20 mA, typical output impedance of 100 Ω, and a bias voltage of +11 to +13 V.

All models in the 3049E series are rated for a maximum shock of 5000 g peak.
The 3049E and 3049E1 operate from –60 °F to 250 °F, while the 3049E2 and 3049E3 operate from –60 °F to 212 °F.
The devices draw between 2 mA and 20 mA of supply current.
