RST’s Inclinometer Casing is engineered to be assembled quickly and accurately for long and short term monitoring in the most adverse field conditions.

Casing sections have built-in couplings that snap together. O-rings ensure that the joint is grout proof. There is no need for solvent cement or tape.

RST casing is offered in 70 and 85 mm diameters. Accessories include grout valves, casing anchors, telescoping sections, and splice kits.

Specto Technology maintain a stock of 2.75 inch (70mm diameter) casing in our Linden, NJ warehouse, to allow speedy delivery to customers in the North-East.

For same-day-pickup, simply give us a call 30 minutes before you arrive, back up your rig or truck to our industrial-sized roller doors and we will load the casing directly onto your vehicle. We are less than 20-miles from NYC and only 10-mins off the NJ Turnpike (Exit #13).

If you require casing shipped to your site or office, our network of freight carriers can deliver casing the FOLLOWING DAY from Washington DC to Boston, if you place an order by 2PM.

Product Information:

Inclinometer casing is a special purpose pipe used in inclinometer installations. It performs three functions:

  • It maintains access for the inclinometer probe, allowing it to obtain subsurface measurements.
  • It controls the orientation of the probe via internal grooves.
  • It conforms to movement of the surrounding ground.

When you buy inclinometer casing, important features to consider are:

  • Casing diameter
  • Groove shape

Movement of the ground causes the casing to deform. Eventually, the casing is sheared off or pinched closed. When that happens, the probe can no longer pass through, and no more readings can be obtained.

In general, larger diameter casing will offer a longer useful life, because it can accommodate more deformation before access is closed to the probe.

85 mm / 3.34 inch casing is the largest diameter. It is suitable for all uses and especially recommended for landslides and long-term monitoring. It is also appropriate for monitoring multiple shear zones or very narrow shear zones.

70 mm / 2.75 inch casing is suitable for construction projects. It can also be used for slope stability monitoring if only a moderate degree of deformation is expected.

The accuracy of inclinometer measurements is directly influenced by the quality of the casing grooves. The best grooves provide a regular, flat surface for the wheels of the probe.

The grooves should be slightly wider than the wheels, to permit some side to side movement as the probe passes through curves. If the grooves are too tight, the wheels will climb out of the grooves and degrade the reading.
