High Performance, Top Mount Accelerometers

The OMEGAROMETER™ Series accelerometers are designed for industrial vibration measurements. These accelerometers feature a hermetically sealed 316L stainless steel case suitable for harsh environments. The ACC793 is a high performance accelerometer with a top cable exit. FM and CSA intrinsic safety approval is an available option.
