Model 340ATM2 is an intrinsic safety IEPE accelerometer
permitting simultaneous vibration and temperature
measurements. 340ATM2 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, 340ATM2 has ¼ -28 threaded holes for stud
mounting on the test object. The 340ATM2 provides wide
frequency response and shock resistance, which is ideal for
industrial vibration monitoring under incidental shock
environment. Senther’s model 20A-L is a MIL-C-5015 3-
pins connector mating cable for the sensor.
