The Dytran 3145A1 is a miniature, hermetically sealed IEPE accelerometer with a ceramic shear sensing element and a 5-40 UNC-2A stud mount. It weighs 2.3 grams and features a 5-44 coaxial connector. The device has a sensitivity of 10 mV/g with a frequency response of 1 to 7,000 Hz (±5%) and 0.8 to 10,000 Hz (±10%), and a resonant frequency greater than 45 kHz. It operates from -60 to 250 °F, supports 2 to 20 mA supply current with a +18 to +30 V compliance voltage, and has an output impedance of 100 µ. The housing is made of 304L stainless steel, and the output polarity is positive for acceleration toward the top. Maximum shock is 3,000 Gpeak and maximum vibration is 600 Gpeak.
The Dytran series 3145 is a miniature, low mass IEPE accelerometer weighing just 2.1 to 2.3 grams. Available with a sensitivity range from 5-100 mV/g, the accelerometer incorporates a ceramic shear sensing element in a robust stainless steel housing, with a 5-40 mounting stud and axial 5-44 connector. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
