DC accelerometers for critical structural monitoring
Measurement Specialties' DC accelerometers, Model 4020 and Model 4030, are designed to provide long-term, stable measurements and are designed to deliver high-resolution measurement and long-term stability in critical structural applications.
Measurement Specialties' DC accelerometers are designed to provide long-term, stable measurements in structural and vibration monitoring applications. The Model 4020 and Model 4030 deliver MEMS capacitive sensing technologies and combine a durable, IP65-rated house with attributes such as a low pass filter output that enhances signal processing for stable operation. Specific uses for the accelerometers include low frequency vibration monitoring, motion measurements and structural monitoring as well as tilt and inclination measurement.
The sensors are available in either a ±2 g or a ±6 g full scale dynamic measurement range, and are offered 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 V dc to 30 V dc 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%.
