Model HV100LF/HV200LF Series Low Frequency Isolated Sensor

Brand: Wilcoxon Sensing Technologies
Wilcoxon’s HV series are innovative accelerometers designed for demanding applications requiring high electrical isolation between the sensor and machine. HV sensors are designed to withstand arcing between the sensor base and its internal electronics to levels as high as 6,000 volts. The sensors offer improved EMI-resistance in areas where high electromagnetic interference occurs such as wind turbines, railway systems and other high-voltage generators. The low frequency series has superior performance down to 0.1 Hz. 

HV series sensors can pass a HiPot test of > 6,000 volts from sensor electronics to mounting base. This high isolation prevents energy from arcing through the sensor offering better protection of the associated equipment. Improvements in EFT and ESD resistance improves survivability during extreme transient events. The HV series come with a variety of mounting options to ensure compatibility with every application.
Features
  • Ultra low frequency sensors
  • Ideal for power generation applications
  • Rapid shock recovery
  • Hermetically sealed
  • Case-base isolation min 6 kV
  • EMI-protected
  • Manufactured in an approved ISO 9001 facility
