swiss made to measure 8952 Schlieren E-mail: info@geosig.com □ Full Scale: ± 2 g (± 0.625, 1, 4, 5 g optional) □ Bandwidth DC to 100 Hz □ MEMS Force Balance Accelerometer □ High shock survivability □ Wide temperature range □ High lifetime stability □ Low power consumption □ Simple test and calibration □ Single Bolt Mounted Enclosure provides up to ± 10° of Levelling Adjustment □ Integrated Bubble Level The AC-43 sensor package is a triaxial MEMs Force Balance Accelerometer designed for urban and industrial applications regarding strong motion earthquake survey and vibration monitoring as well as alarm and switch systems. All these applications require rugged sensors with minimum maintenance and a simple method for periodic testing. The AC-43 accelerometer is based on the modern MEMS (Micro Electro-Mechanical Systems) technology. With its state of the art proprietary circuit design, the sensor is a cost effective and reliable accelerometer. MEMS cells include linear accelerometer sensing elements which measure the capacitance variation in response to any movement or inclination and a factory trimmed interface chip that converts the capacitance variations into analog or digital signal proportional to the motion. The DC response allows the sensor to be repaired, tilt tested or recalibrated. With the help of the TEST LINE the AC-43 accelerometer can be completely tested assuring proper operation. The AC-43 is typically housed in the standard GeoSIG sealed cast aluminium housing with dimensions of 195 x 112 x 95 mm. The housing also incorporates a single bolt mount with three levelling screws. Stainless steel outer enclosure options are available. The AC-43 accelerometer is directly compatible with the GeoSIG recorders. It is also designed to be mounted internally in standard GeoSIG recorders. A digital version is also available which can be used with our Digital Sensor System. REGISTERED FIRM
