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. The model ASC OS 215LN has been developed for the demanding requirements of offshore applications. The robust housing and the connecting cables are designed to work at 1m water depth. These ASC accelerometers therefore benefit from the high stability of the chip technology with a low noise level and a low bias and an excellent scale factor temperature coefficient. The ASC OS 215LN is over a wide temperature range fully compensated and factory calibrated. 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. A very high flexible and rugged cable provides a simple mounting. The ASC OS 215LN is equipped with 1 meter cable as standard. ASC GmbH ■ Advanced Sensors Calibration ■ Ledererstra&e 10 ■ 85276 Pfaffenhofen ■ Germany ■ Tel. +49 (0) 8441 786 547 -0 ■
