Teardrop voltage source piezoelectric accelerometer outputs from 1mV/g to 100mV/g

September 09, 2015 // By Julien Happich
DJB Instruments' IEPE A/127/V is a miniature teardrop integral electronics voltage source piezoelectric accelerometer that uses the unique Konic shear ceramic sensing element developed by DJB Instruments founder Don Birchall.

The element offers unrivaled performance in areas such as cross axis repeatability and temperature stability. The accelerometer's low mass (1.9grams) renders it almost invisible to most lightweight structure vibration measurement applications whilst offering high frequency response and excellent reliability.

With an all welded titanium construction it offers a maximum high operating temperature of 185°C in HT form whilst maintaining no loss of dynamic range. The signal outlet is via the standard KP (M3.5) miniature microdot connector and is recommended for use with lightweight cable assemblies of a maximum 1mm diameter (available from DJB’s extensive cable assembly facility).

The device comes in a wide range of sensitivities from 1mV/g up to 100mV/g output, with standard off the shelf versions available as 1, 10 or 100mV/g. The A/127/V is adhesive mounted and is supplied as standard with a detachment tool to shear the adhesive joints without damaging the internal electronics.
