3217A潜水型加速度传感器

概述

The Dytran 3217A is a low profile IEPE accelerometer with a 100 mV/g sensitivity, weighing just 5 grams. The sensor features a factory molded urethane boot and a 10-foot integral urethane cable, for reliable operation in water depths to 175 psi.

Sensor design incorporates a ceramic shear sensing element for high natural frequency, along with low noise electronics, encased in a rugged lightweight titanium housing. The sensor is base isolated to avoid EMI/ground loop interference and is offered with adhesive mounting capabilities. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
