Model 530A is an IEPE triaxial accelerometer designed fortesting applications. The accelerometer uses shear piezoelectronical element which provides a wide operatingfrequency range. The IEPE sensor combines outstandingcrystals and low noise integral microelectronics to achievevery low sensitivity variation over the operating temperaturerange, compared to other sensing element designs. Theshear element technology also ensures high immunity tobase strain errors. The accelerometer uses a weldedtitanium construction and a light weight 4 pins connector, orintegral cable assembly for lower mass and wider frequencyoperation. Excellent frequency response, both amplitudeand phase, provide the user with a triaxial accelerometerideally suited for structural and component testing, droptests and general laboratory vibration work. The miniaturecube size of this accelerometer enables the test engineeror technician to measure the accelerations of threeorthogonal axes of vibration simultaneously on lightweightstructures. All variations provide reliable measurementsand long-term stability.
