Tri-axial velocity sensor (geophone) in compliance with DIN 45669 for downhole applications.

• Stainless steel IP68 (Diameter: 70 mm, Height: 200 mm, Weight: 3.5 kg)
• Cable length upon request
• Analog output, differential

The downhole sensor uses a movable eccentric disc mechanism for clamping the sensor towards the guidance (inclinometer) tube. This allows clamping and recovering the sensor at a specific depth.

The inclinometer tube must be correctly oriented (notch towards north) and solidly mounted (concrete) into the ground.
