MEMS Capacitive Accelerometer ► Uniaxial ► 4 Wire System ► Amplified Output ► Aluminium Housing / Stainless Steel Housing ► Made in Germany Features ► Range: ±1g to ±200g ► DC Response ► Gas Damped ► Excellent Bias and Scale Factor Stability ► Low Power Consumption ► Single Ended Mode Options ► Customised Cable Length ► Customised Connector ► TEDS Module Applications ► Structural Monitoring and Testing ► Endurance Testing ► Brake Test ► Vibration Monitoring ► Civil Engineering ► Modal Analysis ► Vehicle Testing ► Automotive Ride Quality & Comfort ► Railway Engineering ► Flutter Test Capacitive MEMS Technology The accelerometers are based on a capacitive MEMS technology and can be used in a low frequency response up from 0Hz. Inside the sensor element, the seismic mass is connected with two conductive capacitor plates. If the seismic mass oscillates between the two capacitor plates the capacitance will change. This capacitance change is converted via an ASIC (Application Specific Integrated Circuit) into an analog signal. Description The models ASC 4321 and ASC 4325 have been developed for the demanding requirements of different applications. The highly robust housing and the connecting cables are suitable for the rough application areas in automotive, train, military and so on. These ASC accelerometers benefit from the high stability of the chip technology with a low bias and an excellent scale factor temperature coefficient. The ASC 4321 and ASC 4325 are fully compensated over a wide temperature range and are factory calibrated. Both models are shock resistant up to at least 5000g. As capacitive technology is used, extremely small measuring ranges are possible. The amplified output is easy to use with a data acquisition unit. The signal is endependent from the power between +8VDC to +30VDC. A very high flexible and rugged cable provides a simple mounting. The stainless steel package of the ASC 4325 provides a high resistance to strong environmental influences. The ASC 4321 and ASC 4325 are equipped with 6 meter cable as standard. 21.8 ASC GmbH ■ Advanced Sensors Calibration ■ Ledererstra&e 10 ■ 85276 Pfaffenhofen ■ Germany ■ Tel. +49 (0) 8441 786 547 -0 ■
