Isotron® accelerometer -UNIT IDENTIFICATION THIS SURFACE \ MATES WITH ENDEVCO • General purpose single axis Isotron® accelerometer • Wide frequency bandwidth • Hermetically sealed • Signal ground isolated from mounting surface • IEEE P1451.4 TEDS capable STANDARD TOLERANCE INCHES [MILLIMETERSJ Model 43A is a cost effective general purpose Isotron® accelerometer designed for use in a variety of applications. 43A is a small Isotron accelerometer with a unique cube shape, allowing the sensor to be mounted in two different orientations. The unit is hermetically sealed against environmental 43A features an annular shear ceramic crystal which exhibits excellent output stability over time. The accelerometer incorporates an internal hybrid circuit with TEDS in a two-wire IEPE system which transmits its low impedance voltage output through the same cable that supplies the constant current power. Signal ground is electrically isolated from the outer case of the unit. Polarity inversion protection for the hybrid circuit is inherent in the circuit design. 43A is available in three sensitivities designated by a two digit suffix. The 43A16 has a sensitivity of 100 mV/g, the 43A18 and 43A19 have sensitivities of 500 mV/g and 1,000 mV/g respectively. The customer may select the mounting stud size included standard with the unit. The available stud sizes are 10-32, 1/4-28, M5 and M6. The stud size is designated following a dash after the model number.
