Rugged DC accelerometers suit critical structural monitoring

By combining a durable, IP65-rated house with attributes such as a low pass filter output that enhances signal processing for stable operation, these accelerometers provide high resolution measurement and long term stability in critical structural applications. Specifically targeted applications include low frequency vibration monitoring, motion measurements and structural monitoring as well as tilt and inclination measurement.

The low noise, signal conditioned sensors are available in either a ±2 or ±6g full scale dynamic measurement range, and are offered in a dual-axial (Model 4020) or triaxial (Model 4030) configuration. Sensitivity is 1,000 and 333mV/g, respectively, for the ±2 and ±6g dynamic ranges.

Across both dynamic ranges, the sensors offer a frequency response of 0 to 200Hz, non-linearity of ±1% FSO and transverse sensitivity of more than 3%. Zero acceleration output is 2.5V (±1), excitation voltage is 5-30VDC and excitation current is 4mA. The sensors’ shock limit is 2,000g and operating temperature range is from -40 to +85°C with a thermal zero shift of ±4% FSO and a thermal sensitivity shift of ±5%.

The moulded, rugged housing is nylon 6-6 with 305 GF and brass inserts at the mounting holes.  Each sensor weighs 50g and can be securely screw-mounted using two 1/4" or M6 screws. An integral #24 AWG cable is included for easy connection.
