CSI AC115-M12D Triaxial Accelerometer

Description

The AC115-M12D is a triaxial IEPE accelerometer that captures vibration data along the X, Y, and Z axes simultaneously. It’s ideal for route-based condition monitoring, structural testing, and OEM integration in predictive maintenance systems. Its compact design and M12 connector make it easy to install in tight spaces or on rotating equipment.
