概述
The Dytran model 3191A is an IEPE piezoelectric accelerometer with built-in Faraday shield for electrostatic noise immunity, excellent low frequency response of 0.08 Hz and the capability to resolve vibrations as low asg's RMS.
Available with a sensitivity of 5 V/g, design of the model 3191A incorporates an annular shear ceramic sensing element, packaged in a highly rugged stainless steel housing with a 2-pin MIL-C-5015 axial connector andmounting hole. The model 3191A was designed to be directly compatible with the Dytran model 6194 Immersion Proof sealing boot (sold separately). When used together, the sensor remains fully functional in an IP65 environment. The sensors are hermetically sealed for reliable operation in high humidity and dirty environments and case isolated to avoid EMI/ground loop interference.
