3372B1

The Dytran 3372B1 is a miniature, high-temperature IEPE accelerometer engineered for precision vibration measurements in compact and thermally demanding environments. Built with a quartz shear sensing element and rugged 300 Series stainless steel housing, this sensor is ideal for aerospace, automotive, and industrial applications where space, weight, and thermal resilience are critical. This sensor delivers a sensitivity of 10 mV/g (±15%), making it suitable for measuring acceleration levels up to ±500 g peak. It offers a frequency response of 0.66 Hz to 5,000 Hz within ±5%, and extends up to 10,000 Hz within ±10%, ensuring accurate performance across a wide dynamic range. The resonant frequency exceeds 40 kHz, providing excellent high-frequency response. The electrical noise floor is low, at 0.007 g RMS, and the sensor maintains linearity within ±1% of full scale. It also features a maximum transverse sensitivity of 5% and a strain sensitivity of 0.002 g per microstrain, ensuring accurate readings even in mechanically complex environments. Environmentally, the 3372B1 operates in temperatures ranging from −60 °F to +347 °F (−51 °C to +175 °C) and can withstand shocks up to ±1500 g peak. The thermal coefficient of sensitivity is 0.03% per °F (0.017% per °C), and the sensor is hermetically sealed using an epoxy/welded construction for durability in harsh conditions.
