horizontalverticalindustrial

Product overview
The PS-ML-60 is a dual-output seismic detector (special-type geophone) that provides two separate output channels: one optimized for signal output and one for control/trigger terminals. It is designed for exploration and engineering vibration measurement where simultaneous signal acquisition and control signaling are required.

Applications

• Seismic exploration and field surveys
• Vibration monitoring in civil and geotechnical engineering
• Triggering and control for acquisition systems
