Meggitt’s HV (high voltage) isolated sensors are designed for vibration monitoring in high electromagnetic environments commonly found near wind turbines, including the base and nacelle, and rotating machinery such as bearings, gearboxes. The rugged design and high performing components of the HV series ensures reliable operation in harsh electromagnetic environments without communication loss or delays. 
The sensing element is isolated from the sensor base and casing to offset the effect of high voltage and electromagnetic interference (EMI) often found in wind turbines and VFD/SCR controllers. An isolated pellet offers extra protection for internal electronics. Ceramic housings and hermetic sealing provides isolation up to 6,000 volts promoting long-term stability. Low frequency models have superior performance down to 0.1 Hz.
