HS-1 Seismometer

PRODUCT DETAILS

The HS-1 is an integral component in the vibration monitoring and analysis of machinery. This rugged, self-generating seismic sensor converts mechanical motion into an electrical signal, which is proportional to relative velocity. The HS-1’s dual-coil construction minimizes interference from electromagnetic fields.

Features

  • Natural frequencies from 2.0 to 28 Hz
  • Sensitivities from 460 to 2000 mV per ips
  • Sensitive to motion along their longitudinal axes
