The Dytran series 3211 a low profile IEPE accelerometer with a 10–100 mV/g sensitivity range, weighing just 10 grams. The series includes submersible models which feature a factory molded urethane boot and multiple integral urethane cable lengths available, for reliable operation in water depths to 175 psi.

The series design incorporates a ceramic shear sensing element for high natural frequency and integral low noise JFET electronics, encased within a rugged, lightweight titanium housing. The sensor is base isolated to avoid EMI/ground loop interference and mounts via either a 0.17 hole mount or #8 or M4 mounting screws.

Units are hermetically sealed for reliable operation in high humidity and dirty environments. The submersible model features a miniature thru hole design which allows the sensor to be turned 360° prior to securing for ease of sensor installation.

Features:

• Titanium
• Hermetic
• Case isolated
• 360° cable orientation on various models
• Low noise JFET electronics
• IEPE
• Submersible models available

Applications:

• Modal analysis
• Vibration control
