Product Description

Product Overview

The Wilcoxon HV100LF and HV200LF series are low-frequency accelerometers designed for applications requiring high electrical isolation and improved EMI resistance. These sensors are ideal for power generation, wind turbines, railway systems, and other high-voltage generators, offering ultra low-frequency measurements down to 0.1 Hz and rapid shock recovery. With case-base isolation up to 6 kV and enhanced EFT/ESD resistance, they ensure survivability during extreme transient events.
