General purpose acceleration sensor-G71AT

Product Description

G71AT is an IEPE triaxial seat pad accelerometer designed especially for characterizing whole body vibration in accordance with ISO 2631-1 and ISO 8041. The seat pad incorporates a removable triaxial accelerometer with 5000mV full scale output. The model G71AT is designed for low frequency measurements with a measurement resolution of <1mg. A flexible cable is includes with three BNC connectors for simple interface. 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 accelerometer enables the test engineer or technician to measure the accelerations of three orthogonal axes of vibration simultaneously on vehicle or platform. All variations provide reliable measurements and long-term stability.
