Model 536A is an IEPE triaxial accelerometer designed for industrial applications. The accelerometer uses shear piezo electronical element which provides a wide operating frequency range. The IEPE sensor combines outstanding crystals and low noise integral microelectronics to achieve very low sensitivity variation over the operating temperature range, compared to other sensing element designs. The shear element technology also ensures high immunity to base strain errors. The accelerometer uses a housing isolated construction and integral cable assembly for lower mass and wider frequency operation. Excellent frequency response, both amplitude and phase, provide the user with a triaxial accelerometer ideally suited for structural and machine monitoring, drop tests and general laboratory vibration work. The thin configuration of this accelerometer enables the test engineer or technician to measure the accelerations of three orthogonal axes of vibration simultaneously on compact structures. All variations provide reliable measurements and long-term stability.
