OPERATING GUIDE

MODEL 3312A2T

IEPE ACCELEROMETER

HERMETICALLY SEALED AND CASE ISOLATED

This guide contains:

1) Outline/installation drawing 127-3312A2T

2) Specifications, Model 3312A2T

NOTE:

Model 3312A2T is an IEPE accelerometer with

100mV/g sensitivity and TEDS electronic data sheet

function. A built-in charge amplifier amplifies the

signal generated by the piezoceramic shear mode

seismic element to obtain the 100 mV/g sensitivity.

Model 3312A2T features hermetically sealed

construction and electrically isolated case for "off-

ground" performance. Hermeticity is obtained by

all-welded construction and glass-to-metal sealed

connector. Case ground isolation is by an

electrically isolated insert located in the base of the

instrument. Signal ground return is electrically

isolated from the mounting surface.

Page 2 OPERATING INSTRUCTIONS MODEL 3312A2T IEPE ACCELEROMETER INTRODUCTION The Dytran Model 3312A2T is a ceramic shear element accelerometer featuring IEPE operation and including the IEEE TEDS data sheet function. The self-generating seismic element, converts acceleration to an analogous voltage signal. This very high impedance signal is fed to the gate of a...
