Low bias miniature accelerometer

Dytran Instruments’ Dytran model 3205M1 is a high-performance IEPE accelerometer capable of operating at temperatures up to +175°C and is designed for down-hole drill head vibration monitoring and other low turn-on voltage applications where supply power is limited.

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 3205M1 is ideal for such applications, says the manufacturer, as it is packaged in a miniature titanium housing with a vertical height of just 7.7-mm and was specially designed to operate from +4.0 to +4.5 VDC compliance voltage.

The Dytran model 3205M1 is offered with a 0.33 mV/g sensitivity and is designed with 10-32 stud mounting capabilities. Weighing just two grams, units incorporate a 35-inch integral cable assembly terminating to flying leads.
