Inclinometer Probe

Probe length should match your casing's groove spacing—typically 0.5 m or 1 m between wheel sets. Longer probes average out more data, which works well in uniform soils, while shorter probes capture sharper deformation zones. Kingmach can advise on the best fit based on your borehole depth and expected movement patterns.

MEMS sensors are smaller, use less power, and cost less, making them common in mid-range probes. Servo-accelerometers offer slightly higher precision and better stability over wide temperature ranges. For most geotechnical projects, a well-calibrated MEMS probe gives perfectly adequate results. Kingmach provid both options depending on your accuracy needs.

Yearly calibration is standard for most probes, though heavy use or harsh environments may call for more frequent checks. Zero-shift checks before each survey help catch drift early. Kingmach includes calibration certificates with each probe and offers recalibration services through its support network.

Yes, that's the standard approach. As long as all boreholes have the same casing type and groove orientation, one probe can survey them all. Just bring the probe to each site with a readout unit. Data management becomes easier when you label each casing clearly and log the serial number of the probe used.

Keep the wheels and spring arms clean and check for wear after every few surveys. The connector pins should be dry and free of corrosion—use dielectric grease if you are in damp environments. Rinse the probe with fresh water after use in saline or dirty conditions. Kingmach provides spare wheel kits and cables, so you can swap parts in the field without sending the whole unit back.
