When analysis of very low frequency motion or constant acceleration is required, MEMS accelerometers are necessary. Unlike piezoelectric accelerometers, these sensors respond to 0 Hz and are, therefore, often referred to as DC response sensors.

PCB® Series 3741 DC response accelerometers are offered in a variety of full-scale ranges, from ± 2 to ± 200 g. The units feature silicon MEMS sensing elements for uniform, repeatable performance. Gas damping, mechanical over range stops, and a low profile, hard-anodized, aluminum housing are utilized for added durability. Electrically, the units offer a differential output signal for common-mode noise rejection.

PCB® Series 3711 (single axis) and 3713 (triaxial) DC response accelerometers are designed to measure low frequency vibration and motion, and are offered in full-scale ranges from ± 2 to ± 200 g, to accommodate a variety of requirements. The units feature gas-damped, silicon MEMS sensing elements that provide performance, while hermetically sealed titanium housings provide protection from harsh contaminants. These units are inherently insensitive to base strain and transverse acceleration effects, and offer high frequency overload protection. Electrically, the units offer a single-ended output signal for each channel with power and ground leads.
