MEMS Capacitive Accelerometer ► Uniaxial ► Ultra Low Noise (LN) ► High g-Range ► 4 Wire System ► Amplified Output ► Aluminium Housing ► Made in Germany Features ► Range: ±2g to ±400g ► DC Response ► High Shock Resistance ► Gas Damped ► Excellent Bias and Scale Factor Stability ► Differential Mode 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 Options ► Customised Cable Length ► Customised Connector ► TEDS Module The model ASC 4111LN is an uniaxial accelerometer based on capacitive technology. It is over a wide temperature range fully compensated and factory calibrated. The sensor has been developed specifically for measuring relatively small accelerations, as required in the aerospace or automotive sector, for example. 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 Because 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 independent from the power between +8VDC to +30VDC. The package is hard anodized aluminium that is rugged for automotive, industrial and military applications. A very high flexible rugged cable provides a simple mounting. The ASC 4111LN is equipped as standard with 6m cable. It is a Low Noise version and has a better frequency response. Owing the lower noise the ASC 4111LN provides a higher resolution.
