About the 786LF Low Frequency (Seismic) Vibration Sensors

786LF series delivers clear signals at low frequency, low vibration levels. The low frequency series has superior performance down to 0.1 Hz. The sensors are optimized with extended low-end frequency response and improved signal-to-noise ratio compared to other general purpose models. The sensors are designed with unique circuitry helping prevent washover distortion, a condition that can occur when both high amplitude, slow and fast frequencies are present. The 786LF series can be used for detecting vibration on slow turning machinery such as cooling tower fans and slow-speed gearboxes.
