The accelerometers can measure both static (gravity) and dynamic accelerations. ASC's MF series can be used for very low to medium frequency vibration measurements from 0Hz to 2.5kHz. The MF series features a MEMS sensor element where the seismic mass is connected Description The models ASC 5421 and ASC 5425 have been developed for the demanding requirements of different applications. The highly robust housing an 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 5421 and ASC 5425 are fully compensated over a wide temperature range and are factory calibrated. 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 independent from the power between +8VDC to +30VDC. A very high flexible and rugged cable provides a simple mounting. ASC 5421 and ASC 5425 are equipped with 6 meter cable as standard. ASC GmbH ■ Advanced Sensors Calibration ■ Ledererstra&e 10 ■ 85276 Pfaffenhofen ■ Germany ■ Tel. +49 (0) 8441 786 547 -0 ■
