IEPE tri-axial accelerometer is only 7x7.5x5.6mm

June 24, 2016 // By Julien Happich
The AT/18 from DJB Instruments UK is an ultra-lightweight micro-miniature triaxial Integrated electronic piezoelectric (IEPE) accelerometer featuring three fully independent ceramic shear/mass sensing elements, welded into a Titanium body to minimise risks of signal failure and cross axis issues.

Supplied with an integral 1m cable fitted with an industry standard ¼-28 UNF socket it provides maximum flexibility and can be used with common triaxial cables for extension of signal connection. Weighing in at just 1.2grams and measuring 7x7.5x5.6mm it offers triaxial measurements on the lightest of structures due to its almost invisible impact on mass loading.

The AT/18 is machined to the highest levels of precision working with tolerances of just 12 microns. It goes through rigorous testing to achieve an operational temperature specification of 200°C whilst maintaining no loss of dynamic range. Sensitivity options include 1mV/g, 5mV/g and 10 mV/g with other sensitivities available by request.
