The Dytran model 3003B is a high performance triaxial IEPE accelerometer capable of operating at temperatures up to +347°F (+175°C) and was designed for down–hole drill head vibration monitoring.

Sensors developed for down–hole vibration monitoring must be able to deliver accurate and reliable data, while simultaneously tolerating harsh conditions. Critical characteristics of these sensors include a miniature design, high temperature operation, and the ability to operate at low power levels. The Dytran model 3003B is ideal for such applications, as it is packaged in a miniature titanium housing with a vertical height of just 0.37–inches (9.4–millimeters), is capable of reliable operation at temperatures up to +347°F (+175°C), and was specially designed to operate from +4.0 to +5.5 VDC compliance voltage.

The Dytran model 3003B triaxial accelerometer is offered with a sensitivity of 2 mV/g and 500g range, and is designed with adhesive mounting capabilities. Weighing just 6 grams, units incorporate four permanently attached 22–inch long lead wires.
