MEMS DC Accelerometers Perform Critical Structural Monitoring

MEMS DC Accelerometers Perform Critical Structural Monitoring
Measurement Specialties Inc.

Exploiting MEMS capacitive sensing technologies and state-of-the-art microelectronics, the Model 4020 and Model 4030 dc accelerometers provide long term, stable measurements in structural and vibration monitoring applications. Applications include low-frequency vibration monitoring, motion measurements, and structural monitoring as well as tilt and inclination measurement. They are available in either a ±2g or a ±6g full scale dynamic measurement range and in a dual-axial (Model 4020) or triaxial (Model 4030) configuration. Sensitivity is 1,000 mV/g and 333 mV/g, respectively, for the ±2 g and ±6 g dynamic ranges. Across both dynamic ranges, the sensors offer a frequency response of 0 Hz to 200 Hz, non-linearity of ±1% FSO, and transverse sensitivity of more than 3%. Zero acceleration output is 2.5 V (±1), excitation voltage is 5 to 30 Vdc and excitation current is 4 mA. The sensors’ shock limit is 2,000 g and operating temperature is -40°C to +85°C with a thermal zero shift of ±4% FSO and a thermal sensitivity shift of ±5%.
