Keywords:Measurement Specialties? DC accelerometer? MEMS? testing environment?

Measurement Specialties recently debuted a rugged, triaxial DC accelerometer for steady state, low-g vibration measurements and high-g transient shock measurements. The new piezo-resistive, MEMS-based Model 3803A provides accurate triaxial measurement under harsh operating conditions.

The IP65 rated sensor is hermetically sealed in a welded, stainless steel housing and is designed for testing applications in harsh, high performance installations. The Model 3803A is offered in dynamic ranges from 2G's to 2,000G's and is gas-damped to provide a wide frequency response across all three axes. The unit's MEMS sensing elements include over-range stops for protection to shock levels greater than 5,000G.

The sensor includes integral temperature compensation to provide a stable output over the operating temperature range of -40C to 105C. The Model 3803A is designed to be stud or screw mounted for easy installation in virtually any testing environment.

A variety of optional accessories that extend the 3803A's functionality are also available. These include a 3-channel, precision DC amplifier with an exceptionally low input noise floor of less than 20 ?Vrms and an auto-zero inline amplifier that features five user selectable gain settings with a gain accuracy of 0.5 per cent.

More information regarding the Model 3803A accelerometer can be found here.
