MEMS static response acceleration sensor-P85AT
Product Description
Model P85AT is a static response 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 ±2000mV full scale output. The model P85AT is designed for static or low frequency measurements with a measurement resolution of <1.5mg. A flexible cable is included for simple interface. The accelerometer uses silicon Micro-Electro-Mechanical System (MEMS) sensing element which provides a better operating in low frequency range. The MEMS sensor combines outstanding variable capacitance technology 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.
