Borehole geophone PSO-14E

horizontalverticalindustrial

Product overview
The PSO-14E omnidirectional geophone provides full 0°–360° sensing for seismic and vibration measurements. It combines low damping and high sensitivity in a compact, lightweight housing (Ø25.4×36 mm) and is designed for field use in demanding temperature ranges (-40 to +70 °C). The unit is suitable for petroleum and logging exploration as well as industrial vibration monitoring.
