Isotron® accelerometer MATES WITH MEGGITT x UNIT IDENTIFICATION • General purpose single axis Isotron® accelerometer • Wide frequency bandwidth • Hermetically sealed • Signal ground isolated from mounting surface • IEEE P1451.4 TEDS capable INCHES [MILLIMETERS] Model 41A is a cost effective general purpose Isotron accelerometer designed for use in a variety of applications. 41A is a small hex shaped Isotron accelerometer with a 10-32 top mount connector. The unit is hermetically sealed against environmental contamination. 41A 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. 41A is available in five sensitivities designated by a two digit suffix. The 41A13 has a sensitivity of 10 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.
