Dytran presents model 3237A2 integrated electronic piezoelectric (IEPE) accelerometer. It has been specifically developed to serve the widest frequency bands of Rotor, Track and Balance (RTB), helicopter, airframe, and fixed wing aircraft. Within the industry, the sensors are commonly known as spark plug type because of their identical appearance.

Model 3237A2 offers a sensitivity of 25 mV/g. It is made of stainless steel and is sealed hermetically. This makes it ideal for environments with high humidity and dirt. It can also serve as case isolation for prevention of ground loop/EMI interference. The unit includes a military-style D38999 connector with 3 pins and axial mounting. It also has a mounting thread of 1/4-28 and lockwire holes.
