Description

The ASC 5421 and ASC 5425 models are designed for demanding applications in automotive, train, and military sectors. They feature robust housing and cables suitable for harsh environments. These accelerometers offer high stability with low bias and excellent scale factor temperature coefficient. They are fully compensated over a wide temperature range and factory calibrated. The capacitive technology allows for extremely small measuring ranges, and the amplified output is compatible with data acquisition units. The signal remains stable across a power range of +8VDC to +30VDC. A flexible and rugged cable facilitates easy mounting, with a standard length of 6 meters.

Capacitive MEMS Technology

ASC's Medium Frequency (MF series) capacitive accelerometers use capacitive sensing technology to produce an analog voltage proportional to input acceleration. They can measure both static and dynamic accelerations, suitable for low to medium frequency vibration measurements from 0Hz to 2.5kHz. The MEMS sensor element features a seismic mass connection.

Typical Specifications
  • Dynamic: Range from ±1g to ±200g, Sensitivity from 2000 mV/g to 10 mV/g, Frequency response up to 1000 Hz, Shock limit of ±5000g, Recovery time <1 ms.
  • Electrical: Excitation voltage 8-30 VDC, Supply current 2 mA, Zero acceleration output ±30 mV, Output Impedance 350 Ω.
  • Environmental: Operating temperature range -40°C to +100°C, Storage temperature range -55°C to +125°C, Epoxy sealed for humidity protection.
  • Physical: MEMS Capacitive sensing element, Aluminium/Stainless Steel case, Optional connector, Weight: ASC 5421 - 20g, ASC 5425 - 40g, Cable weight 30g/meter.
Calibration

Factory calibration is provided with the sensor, with sensitivity and frequency response specifications for different ranges. Calibration according to DIN ISO 17025 is available separately.

Ordering Information

Model number, range, cable length, and connector options are specified for ordering. Example: ASC 5421 002 6 A indicates model 5421, 50g range, 6-meter cable, no connector.

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 ■
