131D-BH Triaxial Accelerometer
The 131D-BH is a 3-axis ±4g full scale accelerometer with a noise performance of 1.2 μg/rtHz.
The accelerometer outputs an industry standard +/- 10V full scale output. The 131D-BH is best suited for structural engineering applications (bridge and dam monitoring) when the project requires accelerometers to be deployed in triaxial configuration. The Reftek 131D-BH housing is made of Stainless Steel and is sealed to meet IP68 standards for watertight integrity.
Reftek model 131D Accelerometers provide excellent dynamic range and low noise performance useful when paired with digitizers like the Reftek Wrangler. These accelerometers use a Micro-Electro-Mechanical System (MEMS) variable capacitance displacement sensor. The accelerometer is inherently stable over temperature, with excellent reliability, exceptional linearity over a broad dynamic range, excellent bias stability, and little hysteresis errors or offset drift problems that are usually associated with other accelerometer designs. The model 131D-BH is suitable for borehole sizes between 3-3.5 inches.
