Product Description

Model Y31AS is an intrinsic safety IEPE accelerometer permitting simultaneous vibration and temperature measurements. Y31AS 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. Integrated thermal sensor transfer the temperature output by voltage signal. 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. The standard MIL-C-5015 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, Y31AS has ¼ -28 threaded holes for stud mounting on the test object. The Y31AS provides wide frequency response and shock resistance, which is ideal for industrial vibration monitoring under incidental shock environment.
