Low frequency accelerometer Amphenol HV202LF with PZT shear sensing element and stainless steel case
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 environments. They offer ultra low-frequency measurements down to 0.1 Hz, rapid shock recovery, and can withstand arcing between the sensor base and internal electronics up to 6,000 volts. Improvements in EFT and ESD resistance enhance survivability during extreme transient events.
