Horizontal geophone PS-3/80

verticaltriaxialindustrial

Overview
The PS-3/80 geophone is a passive, low-frequency sensor designed for seismic and vibration measurements. It uses a rotating-coil system to reduce lateral shock sensitivity and is available in configurations for P-wave or S-wave detection. Suitable for single-component or three-component setups in geophysical exploration, engineering vibration monitoring and portable instrumentation.
