The REF TEK 131B-01/3 is a Triaxial Accelerometer which provides excellent dynamic range useful when used with 24-bit digitizers like the REF TEK 130 Series. These accelerometers use a Micro-Electro-Mechanical System (MEMS) variable capacitance displacement sensor. Because no coils or magnets are used, the accelerometer is inherently stable over temperature, with excellent reliability, linearity, hysteresis, and noise levels. More than 15,000 of the MEMS elements are in use for oil and gas exploration.

The 131B-01/3 is a Ôø‡4g full scale accelerometer with 2 Ôø‡g2/Hz noise level and is best suited for structural applications (building, bridge, dam monitoring) when the project requires accelerometers in triaxial configuration.

The 131B-01/3 housing is anodized machined aluminum. The case is sealed to meet IP67 standards for watertight integrity.
