This file is the instruction manual of the 7298 triaxial microtron variable capacitance accelerometer.
This document provides step-by-step instructions for installing and checking out the Endevco 7298 triaxial accelerometer. It covers mounting with compatible cable assemblies, signal assignments, and performing a 2g turnover test to verify zero measurand output and sensitivity. The manual also includes details on mounting surface preparation, screw torque, and alternative adhesive mounting options for permanent or temporary installations.
The 7298 is a rugged, variable capacitance accelerometer designed for aerospace and automotive applications, featuring internal gas damping and hermetic sealing. It operates from 6V to 45Vdc and provides a linear output from 0.5Vdc to 4.5Vdc per axis, with a 2.5Vdc reference for differential mode.
| Excitation Voltage | 6 Vdc to 45 Vdc |
|---|---|
| Output Range | 0.5 Vdc to 4.5 Vdc |
| Reference Voltage | 2.5 Vdc |
| Mounting Screws | 4-40 x 3/4 inch Socket Head Cap Screws |
The 7298 operates from 6 Vdc to 45 Vdc.
Perform a 2g turnover test on each axis using a dc power supply, millivolt voltmeter, and test leads to record output voltages and calculate sensitivity and ZMO.
The Endevco Model 3907 Cable Assembly is recommended, featuring a Glenair® Mighty Mouse series 800-018 connector.
Bacon Industries LCA-9 is recommended for permanent installations.
