Description

OMEGA’s model ACC104A laboratory accelerometer is ideal for use where accurate structural testing is required. The ACC104A is lightweight, very small and is recommended for applications where low accelerometer weight is critical. It has a 10 mV/g output which can measure vibrations up to 10,000 Hz. The ACC104A has a stainless steel case with a flat surface for adhesive mounting, and an integral side exit coaxial cable.
