Description	N/A The Dytran 3062A series is a family of IEPE piezoelectric accelerometers, expressly designed to cover most wind-band frequency vibration measurement points of Rotor, Track and Balance (RTB); airframe; helicopter; and fixed wing aircraft. The industry has commonly referred to these sensors as "spark plug-type", due to their similar appearance. Available in two models with sensitivities of 10 mV/g or 25 mV/g, 3062A series units feature a hermetically sealed stainless steel construction for use in high humidity and dirty environments, as well as case isolation to avoid EMI/ground loop interference. Both models feature a top mounted military-style 3-pin Bayonet connector, 1/4-28 mounting threads and lockwire holes.	N/A The Dytran model 3077A is an IEPE piezoelectric accelerometer, designed expressly for Rotor, Track and Balance (RTB) and other high-frequency aircraft vibration monitoring applications. Offering a sensitivity of 10 mV/g, frequency response of 1.5 to 5,000 Hz, and a 3-foot integral cable, the distinguishing feature of model 3077A is the Dytran developed integral mounting bracket design, facilitating improved sensor performance while eliminating costs associated with separate mounting brackets. The miniature accelerometer is mounted within the bracket at the point where the cable and bracket are joined. It also offers reduced mass, as compared to conventional sensors and mounting brackets. Dytran's model 3077A is hermetically sealed for reliable operation within high-humidity and dirty environments as well as case isolated, to avoid EMI/ground loop interference.	N/A Expressly designed for use in Health and Usage Monitoring Systems (HUMS), the Dytran model 3078A is an IEPE piezoelectric accelerometer, featuring a sensitivity of 10 mV/g with a frequency response of 1.5 to 5,000 Hz in a highly rugged stainless steel package weighing 20 grams. The distinguishing feature of model 3078A is the Dytran developed integral mounting bracket design, facilitating improved sensor performance while eliminating costs associated with separate mounting brackets. The miniature accelerometer is mounted within the bracket at the point where the cable and bracket are joined. It also offers reduced mass, as compared to conventional sensors and mounting brackets. Model 3078A is hermetically sealed for reliable operation within high-humidity and dirty environments as well as case isolated, to avoid EMI/ground loop interference.	N/A Designed expressly for Health and Usage Monitoring Systems (HUMS), the Dytran model 3079A is an IEPE piezoelectric accelerometer, featuring a sensitivity of 10 mV/g with a frequency response of 1.5 to 5,000 Hz in a highly rugged stainless steel package weighing 11 grams. The distinguishing feature of model 3079A is the Dytran developed integral mounting bracket design, facilitating improved sensor performance while eliminating costs associated with separate mounting brackets. The miniature accelerometer is mounted within the bracket at the point where the cable and bracket are joined. This unique design also offers a reduced mass, as compared to conventional sensors and mounting brackets. Model 3079A is hermetically sealed for reliable operation within high-humidity and dirty environments as well as case isolated, to avoid ground loop interference.	N/A Expressly designed for commercial and military aircraft vibration monitoring, the Dytran model 3168F is a ring-style IEPE piezoelectric accelerometer incorporating the use of high stability quartz shear technology. The model 3168F if offered with a 10 mV/g sensitivity and features a miniature thru-hole design, allowing the sensor to be turned 360° prior to securing for ease of sensor installation. Units are hermetically sealed for reliable operation in high-humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference. Case ground isolation is achieved by internally isolating the accelerometer element, complete with Faraday shield, from the outer housing. The Dytran model 3168F features an integral 4-foot molded Viton™ cable, terminating in twisted shielded pair flying leads. Custom lengths and connectors are also available; please consult the factory for details.
