The Model 704D "ring-shaped" Piezoelectric Accelerometer permits easy installation in locations that are inaccessible with standard shaped units. The mounting arrangement of this design, using a bolt-down technique through a center clearance hole, allows complete 360-degree rotation of the output connector to any convenient position.
Although the unit is very small in size and lightweight, the unique and proven case design provides complete mechanical isolation of the sensing element so that the accelerometer is insensitive to mounting strains, bending stresses, cable whip, pressure variations and most heat transients. Internal electrical isolation minimizes ground loop problems from noise currents.
