V310 series industry vibration transducer, IEPE sensor,accelerometer,

Model V310 series is an industrial piezo-electrical accelerometer permitting vibration measurements. V310 features an annular shear ceramic crystal which exhibits excellent output stability over time. The accelerometer incorporates an internal circuit with in a two-wire system which transmits the 4~20mA current output through the same cable that supplies the voltage excitation. 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. In addition to adhesive mounting, V310 has ¼-28 threaded holes for stud mounting on the test object. The V310 provides wide frequency response and shock resistance, which is ideal for industrial vibration monitoring under incidental shock environment. output signal selectable as Vibration real wave velocity output, RMS output, RMS Peak output: mm/s Velocity output...
