Horizontal geophone PSO-15M1-2400HT

verticalindustrialfor high temperatures

Overview
The PS(H)-8N-900HT, PSO-15M1-2400HT and PSO-15RN-2400HT are omnidirectional high-temperature geophones engineered for petroleum exploration, well logging and industrial vibration monitoring. These models provide stable seismic and vibration detection across a full 0–360° operating angle and are specified for continuous operation in elevated temperature environments.

Key features

• Full omnidirectional operation: 0–360° operable angle.
• Low damping and high sensitivity in a compact, lightweight form factor.
• Designed for continuous use in extreme temperatures (models rated from -40°C up to +200°C or +240°C depending on model).
• Manufactured with dedicated processes and materials to ensure stability in high-temperature conditions.
