Micro acceleration sensor-M70AS
Product Description
M70AS is a miniature IEPE single axial accelerometer permitting simultaneous shock and
vibration measurements. M70AS features an annular shear ceramic crystal which exhibits excellent output stability over time. The accelerometer incorporates an internal circuit 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 connected to the outer case of the unit. Isolated mounting adapter is available. Polarity inversion protection for the amplify circuit is inherent in the circuit design. The welded titanium construction provides a lightweight hermetic housing. The miniature M3 glass insulated connector provides long-term stability over the operating temperature range. The M70AS provides wide frequency response, which is ideal for dynamic vibration and shock measurement especially for lightweight structures and drop testing for the packaging industry. Model 12 is a M3 to BNC breakout cable for the sensor.
