Inclinometers

G1-SINC Digital Inclinometric Measurement System

The G1-SINC digital inclinometric system consists of:

• Biaxial digital inclinometer probe with MEMS sensor
• Bluetooth interface control unit integrated into the cable reel
• 50 m cable with electrolytic copper metal ends
• Ghibli capture software
• Witness probe complete with 50 m cable
• Wellhead cable lock for positioning assurance
• Processing software (optional)
• Pre-configured computer (optional)

Inclinometer data is acquired and transferred directly inside the probe and sent to the surface via digital transmission. A Bluetooth transmitter is mounted in the cable reel. The data conversion is 22 bit, ensuring a precision of 1/20000sen(α). The probe integrates a temperature sensor. The connection cable is graduated with a metal ring every 50 cm and protected by a high-resistance sheath with an internal stainless steel core.

Witness Probe

This probe has mechanical characteristics similar to the inclinometer probe but contains no sensors. It checks the accessibility of the inclinometer tube. Supplied with a cable graduated every meter. It is designed to be slimmer and heavier than the real probe, with smaller wheels, for easier fit in tubes with defects.

GHIBLI-D Software

Installable on Windows PC or tablet, the software allows data acquisition from tests conducted on two or four guides. It lets users set the sampling interval and survey depth, and displays readings, probe depth, and temperature in real time. It records data upon operator command and allows the correction or repetition of a previously taken measurement. The software calculates checksum averages on site and shows the result onscreen. It displays internal battery voltage and generates CSV format files compatible with EXCEL for each test.

Cable Block for Wellhead

This accessory creates a contact and stop point for the struts that graduate the cable, allowing precise depth positioning for comparable readings. The contact point is made of brass.

G1-SINC D Probe

The sensitive element is a latest generation MEMS sensor. The probe body is made of AISI 316 stainless steel. Large diameter wheels enhance stability and help bypass obstacles in the guides. The design provides better resistance to orthogonal stresses, improving the accuracy of the Y sensor readings. The G1-SINC D probe fits inclinometric tubes from 79 mm to less than 49 mm. The software is intuitive and communication with the PC occurs via Bluetooth, eliminating the need for physical cables.
