3D geophone X

horizontalverticalindustrial

Overview
The X Series geophones are single-axis sensors designed for seismic and vibration acquisition in industrial exploration, civil engineering and hydrological studies. Vertical orientation versions are available; suitable for array deployment and field surveys.

Applications

• Oil and coal exploration
• Civil and geotechnical engineering monitoring
• Hydrological vibration analysis
• Seismic data acquisition and array surveys

Product category
Medium frequency geophones (nominal range 4.5 Hz–14 Hz); vertical orientation available.

Key features / technical highlights

• Series: X Series — available models PS-7X, PS-8X, PS-10X, PS-14X.
• Nominal frequencies covering 7–14 Hz for medium-frequency seismic acquisition.
• Standard nominal resistance ~395 Ω; parallel-resistance sensitivity and damping values provided for impedance matching.
• Low distortion and high spurious frequency performance for reliable seismic data.
• Compact dimensions (25.4 × 34 mm) and wide operating temperature range (-40 °C to +70 °C) for field deployment.
• Maximum acceleration limit 1.5 g and inertial mass 11 for stable dynamic response.

Ordering & compatibility

• Select model according to center frequency and the recording-system input impedance (reference parallel resistances shown).
• Mounting: compatible with standard geophone bases and array frames; verify orientation (vertical version available).
• Storage and shelf life: recommended storage conditions to preserve sensor performance; check weight and dimensions when integrating into arrays.
