Wilcoxon HV100LF and HV200LF Series Low-Frequency, High EMI Resistance Accelerometers
Product Overview
The Wilcoxon HV100LF and HV200LF series accelerometers are designed for ultra low-frequency measurements requiring high electrical isolation and superior EMI resistance. Ideal for demanding applications in power generation, wind turbines, railway systems, and other high-voltage environments, these sensors offer rapid shock recovery and improved survivability during extreme transient events. They provide superior performance down to 0.1 Hz and can withstand arcing between the sensor base and internal electronics up to 6,000 volts.
