Model 341AT is an water proof IEPE accelerometer permitting vibration and temperature measurements. 341AT features an annular shear ceramic crystal which exhibits excellent output stability over time. The accelerometer incorporates an internal circuit with 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 internal shielded and isolated from the outer case of the unit. Polarity inversion protection for the amplify circuit is inherent in the circuit design. The welded stainless-steel construction provides a hermetic housing. Internal glass insulated connector provides long-term stability over the operating temperature range. Side outlet cable enable the compact installation and discretional cable direction. In addition to adhesive mounting, 341AT has Ø6.4 through holes for screw mounting on the test object. The 341AT provides wide frequency response and shock resistance, which is ideal for industrial vibration monitoring under incidental shock environment.
