Expressly designed for commercial and military aircraft vibration monitoring, the Dytran model 3168D2 is a ring style IEPE piezoelectric accelerometer incorporating the use of high stability quartz shear technology. Model 3168D2 features mechanical and electrical filters that effectively eliminate ultra–high frequency energy that can cause signal saturation, common in high speed gearbox applications, and act as a barrier to "zero shift" phenomena in the data. The filters suppress the sensorÍs own natural frequencyto assure correct "in–band" vibration measurements during all test applications. Model 3168D2 is case isolated to prevent ground loops in the measurement system.

The sensor is available with a sensitivity of 10 mV/g and a 1Hz to 10,000Hz frequency range (±3dB). The rugged, stainless–steel case is hermetically sealed for reliable operation in high humidity and dirty environments. The integral Teflon^¬ cable for Model 3168D2 terminates in twisted shielded pair flying leads. The 3168D2 mounts via a 10–32 thru hole mounting screw which allows the sensor to be rotated 360° about its mounting hole to allow the cable to exit in any convenient direction. Custom cable lengths and connectors are also available; consult the factory for details.
